It is very important to clarify which one, now that Conan 2. 0 ? requires(, visible=False) trait. Click here to read the latest documentation. Others can be added eventually. 11; We have pkg/1. 2u zlib/1. In this case, this is not directly causing a conflict, but instead the first value to be defined is the one that will be prioritized and will prevail. --json output. See the requires() reference for more information The version overriding mechanism from downstream consumers to resolve conflicts cannot be implemented either with git repos, as both the name and the version of the package is not defined. CMakeToolchain . Conan support version-ranges, like Caution. For overriding in my conanfile. Conan. So the dependency graph can be constructed without errors, and the wine/1. If you don’t want to deploy and maintain your own Artifactory instance, you can isolate your project from changes in upstream remotes, for example ConanCenter, using recipe revisions and lockfiles (please, read linked Conan documentation for more detailed explanation). Just in case, current Conan best practices recommend not to use user/channel for information that changes overtime, but consider them to be For simple cases the attribute syntax can be enough, like tool_requires = "cmake/3. Reload to refresh your session. When I run conan install . Nice feature! 👍 I wonder why there is no similar functionality for lock create command where it could make sense with version ranges? Originally posted by @ytimenkov in #9195 (comment) Summary: Conan 1. yml . Read the blog post * Add integration test for lockfiles with overridden requirements * Use 'override=True' in lockfile test (this reproduces bug #8870) * Include overridden requirements in dependency graph This fixes bug #8870, but it changes the layout of dependency graphs and breaks several existing tests. txt¶. e. Managing a large number of dependencies using the same testing frameworks is made more manageable by being able to override test_requires across projects. I would like to add a requirement to my projet and link this requirement in static. The conanfile. Now I say I want to test with multiple versions of msvc and I also have mingw and cygwin versions of gcc installed, how do I explicitly select the msvc compilers in a conan profile? 可选参数 user/channel覆盖依赖 前期是对 conan 文档 v1. 11 Steps to reproduce (Include if Applicable) I encountered this while packaging open When a conan install is executed, it will check in the local cache first and if not in the remotes what pkg versions are available and will select the latest one that satisfies the defined range. You can use environment variable I have a question about how revisions are supposed to work with packages that can produce multiple binaries depending on different requires. The problem with it is that it is very important to be consistent across all commands (conan lock, conan install, conan create, conan graph info, conan test), and this was a constant source of issues, debugging and support, and specially regarding reproducibility. py or to a recipe file e. Please, do not abuse For more information about the init() method visit init(). 4 Current cubicinterpolation has a dependency on boost/1. Understanding CMake generators ¶ The CMake client offers a variety of generators to create build system files. settings . conf and they will affect both the “build” and the “host” context. Conan 1. Just "magically override the recipe". This is because regular requires cannot be overriden/injected from profiles. This is supposed to be used exclusively when a package will only work with that configuration, and fail otherwise. Please update to Conan 2, click here to read the Conan 2 documentation Consumers can define requires = "pkg/latest@user/testing" and when the graph is evaluated, it will be directly replaced by the pkg/0. Can be any string, not necessarily a number, so it is possible to have a “develop” or “master” version. Are you passing exactly the same configuration to both commands (settings, options, etc)? root_package (Optional, Defaulted to all packages in deps): fnmatch pattern of the package name (“OpenCV”, “Boost”) from which files will be copied. We want to expose only the list of dependencies ( lib/version@user/channel) to the developers, not the logic we put in conanfile. Hi @Ignition. The docs say this explicitly. It is just a wrapper for subprocess. But the case for resolving conflicts among several test_requires makes sense, so lets add it, and try to warn in the documentation about the possible side effects. All the commands that take a profile as an argument, from Conan v1. Some of the information on this page references deprecated features which will not be carried forward with the new release. Conan has an “update” concept, that allows to query servers for Environment details Operating System+version: Windows 10 Compiler+version: msvc 193 Conan version: 2. 0 as dependency. Note that in the general case, the recommended approach is to have the generators defined in the conanfile, and only for the --requires use case, it would be more necessary as command line argument. By the way, you don't mention the Conan version. This Fix: Fixing --require-override over conditional requirements() method. 4 Python version: 3. 39 added --require-override, but on Installing dependencies . As tool_requires are not visible, they don’t define headers or libraries and they Hi @paulharris. In this section, we Conan Center has stopped receiving updates for Conan 1. Skip to content. 32. By default, it is less deterministic, one conan install can resolve to pkg/1. My package outputs a exe with OpenSSL statically linked, so OpenSSL is only required for build and thus a 'build_requires'. Just "make a local copy of the recipe". ConanCenter FAQ Docs Blog. 0, but I am missing an important option on the CLI. X" legacy Conan version, which is no longer recommended. Tutorial; Versioning; Edit on GitHub; Versioning¶ This section of the tutorial introduces several concepts about versioning of packages. py We are planning so, because we are creating a wrapper around conan which will have several logic and checks. Conan version: 1. 1 20180905 We are creating multiple libraries to be used throughout our group's development. The The problem I am trying to override a transitive requirement from a build requires. 10. 本文档翻译 No, if the project declares the override/require to D it will use it in the whole graph, in general, any intermediate require resolves conflicts upstream. But when I not use override it can still resolve that override¶ The same as the force trait, but not adding a direct dependency. type (Required): Currently only git and svn are supported. Take the following example: import json import os from conans. Thanks for your report. 4 version, but for some reason grpc hasn't been updated yet. 13. This will generate the following files after a conan install (or when building the package in the cache) with the information provided in the generate() method as well as information translated from the current settings:. lock is implicit # display info for matrix/1. Its usage should be avoided whenever possible, and updating versions or version ranges in the graph to avoid the conflicts without overrides and forces is the recommended approach. 5 Python version: 3. But I can't even figure out how to get the recipe. io Conan 2-only remote is now available. Ahajha opened this issue Oct 8, 2022 · 2 comments Comments. 23. xxx configuration can only be defined in global. Since cpython is a tool_requires rather than normal requires, the --require-override has no effect. so in Linux, are loaded at runtime. 0, the former test_requires() form is recommended. 书签管理 . 1o") doesn't solve it, as it just introduce a direct and conflicting tool_requires to openssl, which doesn't make much sense. And how to override a recipe? I see stuff about @user/stable, Conan 0. configurations is not necessary. 0 handles propagation of What is your question? Adding this ticket to look into this - could be a potential feature or document a proper way of dealing with this. We deploy Hi @at185190. 2 its conan info which succeeds and conan create/install which show conflicts. Conan is an open source, decentralized and multi-platform package manager for C and C++ that allows you to create and share all your native binaries. If there is conflict somewhere in the graph, because of diamonds, then it might be impossible to fix the conflict without modifying recipes. Also, for the new toolchains and generators, you can set the new win_bash tool_requires dependencies are private to each package, they cannot be changed by other packages, because that would break many package builds. However, I need some packages which are uploaded to the Artifactory using a Linux profile. 0 requires explicit overriding or force to gmp/version, to avoid introducing these issues. 0 and gcc/2. x packages. Hi @actual-daniel. (So many of the ideas online don't seem to work with conan 2. Anything that is linked into consumer packages like all type of libraries (header only, static, shared) most likely are not build_requires but regular requires. 0, because that is now the default, built-in behavior. py reference user/channel, version@user/channel or pkg/version@user/channel (if name or version declared in conanfile. So far so Conan is an open source, decentralized and multi-platform package manager for C and C++ that allows you to create and share all your native binaries. Requires. #11123. Using recipe revisions and lockfiles . txt for consuming dependencies, a conanfile. If both profiles are provided, Conan will build a graph with some packages associated with the host platform and some build requirements associated to the build platform. Howtos; How to manage shared libraries; Edit on GitHub ; How to manage shared libraries Shared libraries, . 22. However, our conanfile has a mistake (my bad), similar to that alluded to in #654 (comment), but for other reasons. It will generate toolchain files that Using the python file does not require it to control the building. I tried conan download, but that seems to squirrel the files away in some cache. Conan 2. Conan is a dependency and package manager for C and C++ languages. But if the source code is available in a repository, you can directly get it from there: We mirror and customize some packages from CCI to our conan repositories in Artifactory. It cannot be undone or overwritten from downstream. This includes a new method named validate(), and a new package_id mode named BINARY_INVALID. Nobody consumes this particular As it can be seen, it allows to define custom user CMake configurations besides the standard Release, Debug, etc ones. Read the blog post . tools. Thanks for contributing an answer to Stack Overflow! Please be sure to answer the question. For our use case it would also be sufficient to replace the build requirement for the whole graph. 7. 白天 夜间 首页 下载 阅读记录. Caution. If the settings. At the moment, I am trying to get our packages ready for conan 2. 2. Moving build-requires to requires is not a good idea if they are real tools (like cmake). Therefore, when I call conan install conan tries to build all the dependencies needed. conanfile. You can use environment variable conandata. The project uses a large number of libraries, most of which are self-sufficient. [requires] poco/1. Tutorial; Consuming packages; Using build tools as Conan packages; Edit on GitHub; Using build tools In the second case I can think of a script to collect versions and options from the lockfile and put it as --require-override and -o arguments for the conan create command. As a rule of thumb, downstream defined values always override upstream dependency values. 1 one. Make sure to specify it directly in the recipes that need the paths shortened in Windows. 21. In this section we are going to learn how to create a recipe for a tool require. If enabled, it will copy the files from the local cache to a subfolder named as the package containing the files. You switched accounts on another tab or window. Downloads. There is no error_on_override in Conan 2.

Please, do not abuse You signed in with another tab or window. 3 OS: CentOS 7. It is possible that when there are diamond structures in a dependency graph, like the one seen above, different recipes might be defining different values for the upstream options. Some things that will be defined in this file: Conan v1. If you inspect the conanbuildinfo. 2 is published, and a new conan install (by users, or CI), will automatically pick the i. It also integrates with all build systems like CMake, Visual Studio (MSBuild), Makefiles, SCons, Important. Bugfix: Force conan_server to use pyjwt>=2. Also, it is not necessary to have a conanfile. Don’t use public members for custom fields or methods in the recipes. I tried conan copy, but it doesn't exist. That cleanup is certainly a good idea, anyway, but I still wanted to let you know You signed in with another tab or window. 9. call(). This command will first export the recipe to the local cache and then build and create the package. Take into account that the same package (executable or library) can appear two times in the graph, in the host and in the build context, with different package IDs. A Conan package reference is the The question was asked because I want to solve this in the test_package of a conan package I create. Yes, that is definitely a conflict, let me illustrate with some realistic example: We have gtest/1. Without revisions, the workflow is Cre Conan Center has stopped receiving updates for Conan 1. If some build requirement is defined in the profile, it will overwrite the build requirements defined in package recipes that have the If we override the build_requires of the base recipe to which the command is referencing, that do not propagate upstream. folder: (Optional, Defaulted to False). This YAML file can be used to declare specific information to be used inside the recipe. If using a lockfile is intended, like in CI, it is better that the argument --lockfile=conan. When the environment variable CONAN_PRINT_RUN_COMMANDS is set to true (or its equivalent print_run_commands conan. txt: [requires] cubicinterpolation/0. Useful to avoid conflicting imports of files with the same name (e. build_requires are designed for packaging tools, utilities that only run at build-time, but are not part of the final binary code. Conan will propagate the proper information to the consumers: "why conan is overriding my test_requires, these are my private tests, with my private code, Conan should not override my test_requires" This was actual feedback in the past, and this is why this is not a bug but test_requires are private (not affected by downstream recipes, and not affecting downstream recipes) by design, more often the test_requires are quite The second line will override the openssl/1. We already explained Conan settings and options and how to use them to build your projects for different configurations like Debug, Release, with static or shared libraries, etc. License). In both cases, we did not specify anywhere that we wanted to build the application in Release or Debug mode, or if we wanted to link against static or shared libraries. 30. e. x). 0 Steps to reproduce Create conanfile with overridden dependency and requires in package_info from conan import Generated files¶. Overrides will no longer be implicit, so if there is any kind of version conflict upstream in the dependency graph, a "conflict error" is raised. Environment Details (include every applicable attribute) Operating System+version: ubuntu18 Compiler+version: Conan version: 1. 0 Release. 0 is out and that is the latest one. Some packages include both libraries and executables - and Skip to content. Follow their code on GitHub. Consider the following test: def test_profile_override_conflict(): client = TestClient() test = textwrap. json, in the output you will see if some binary is missing. I'm creating a conan package for a Windows profile. 75. Navigation Menu Toggle Tool requires packages¶ In the “ Using build tools as Conan packages ” section we learned how to use a tool require to build (or help building) our project or Conan package. 浏览 316 扫码 分享 2023-07-05 17:53:43. conf configuration variable, under [general]) then all the The second line will override the openssl/1. 0"), and it also depends, normal require zlib/1. When type is svn it can contain the peg_revision. tool_requires("openssl/1. Conan Center has stopped receiving updates for Conan 1. For example, “exporting” the source code files, together with the conanfile. i would imagine something like this would work for me: Consumers can define requires = "pkg/latest@user/testing" and when the graph is evaluated, it will be directly replaced by the pkg/0. Reference; Extensions; Python requires; Edit on GitHub; Python requires¶ Introduction¶ The python_requires feature is a very convenient way to share files and code between different recipes. As the later is going to disappear in Conan 2. But you can simplify the conanfile. dylib in OSX and . The force and override traits to solve conflicts are not recommended as a general versioning solution, just as a temporary workaround to solve a version conflict. 1. ), and can be used to develop for all targets including embedded, mobile (iOS, Android), and bare metal. url (Required): URL of the remote or auto to capture the remote from the local working copy (credentials will be removed from it). But if the source code is available in a repository, you can directly get it from there: Poco is the name of the package, usually the same of the project/library. This can be addressed in different ways: In the ConanCenter recipes, updating them to align versions, if possible (it is not always possible to do that for every combination of Important. 1, B require C/0. $ conan lock create -h WARN: Downgrading cache from Conan 2. 0 ends up in the build context with build: False; In the case of adding the dependency with test_requires, the requirements get added in the host context so do not overwrite the build_requirements (as the dependencies are keyed on the reference and context). 13 introduced reporting conflicts between requires and build_requires graphs. The cli argument has been removed in Conan 2, it was terrible regarding UX. 可选参数 user/channel; 覆盖依赖. 4. The CMakeToolchain is the toolchain generator for CMake. Recipe revisions and lockfiles can be used to define exactly the Some packages include both libraries and executables - and the way Conan 2. You positional arguments: path Path to a folder containing a conanfile. But configurations defined in a profile [conf] will only affect the respective “build” or “host” context of the profile, not For simple cases the attribute syntax can be enough, like tool_requires = "cmake/3. There are a few limitations that should be taken into account: name and version fields shouldn’t be inherited. If there is no transitive dependency to override, this require will be discarded. If some build requirement is defined in the profile, it will overwrite the build requirements defined in package recipes that have the same package name. 0 $ conan create. 3. The tool_requires and test_requires methods are just a specialized instance of requires with some predefined trait values. It’s important to check the Migration Guidelines to ensure you are using the most up Hi @AndreyMlashkin. If we override the build_requires of the profile, Setting the values in configure() won’t allow to override them and it will make really hard (even impossible) to resolve some conflicts. package_folder, are reserved for Conan. That means that the application executable needs to know where are the required shared libraries Recall some hints about configuration scope and naming: core. Generators are intended to create files for the build systems to locate the dependencies, while the deployers main use case is to copy files from the Conan cache to The version overriding mechanism from downstream consumers to resolve conflicts cannot be implemented either with git repos, as both the name and the version of the package is not defined. That is because Conan, if not instructed The second line will override the openssl/1. py, aimed at simple consumption of dependencies, but it cannot be used to create a package. py recipes use a variety of attributes and methods to operate. If a test_package folder (you can change the folder name with the -tf argument or with the test_package_folder recipe attribute) is found, the command will run the consumer project to This way the first entry in the PATH variable will be /other/path but the PATH values declared in the requirements of the project will be appended at the end using the system path separator. In our case, we have a "core" project that used in all our I agree completely with @SeanSnyders. I don't know if it helps but if you want to automate the check task you could run a conan info . But otherwise it is a way better implementation and The conan create command creates a package from the recipe specified in path. You can use environment variable Overriding options¶. It is important to understand the lockfiles as a snapshot of a given dependency graph versions, that allows to reproduce exactly those graph versions, under the same initial conditions, by constraining the possible version ranges that exist. py. 2u. if a package is build_requires() somewhere, we make it build_requires() in all of its consumers - or if it is not really a valid candidate for build_requires() we'll make it requires() everywhere). Note that the --update argument will look into all the remotes specified in the This way the first entry in the PATH variable will be /other/path but the PATH values declared in the requirements of the project will be appended at the end using the system path separator. Build-requires are private to the node that declares them, so they cannot be overridden from other nodes. Conan support version-ranges, like This way the first entry in the PATH variable will be /other/path but the PATH values declared in the requirements of the project will be appended at the end using the system path separator. g. Multi-configuration lockfiles¶ We saw above that Methods source() Method used to retrieve the source code from any other external origin like github using $ git clone or just a regular download. test. The method form can be necessary for conditional or parameterized requirements. $ conan graph info. That feature was born from the conan github repository issue (a feature request). I am transferring this issue to conan-center-index repo. py is perfectly suited for simple consumption of dependencies. model. py syntax with requires = (<ref>, "override"), <ref>, <ref>, i. Closed Ahajha opened this issue Oct 8, 2022 · 2 comments Closed [bug] In some situations, Conan requires you to override a package when it is already overridden #12274. Of course, it is not true that we won’t run anything from those I'm beginners in Conan. I'd rather just use requires with its downsides just to make the requirement easier to manage. zzz can be defined in global. 4 openssl/1. Thanks in advance In Conan 1. utils. 3 I just tried to build some software with conan on a machine configuration where I have never build this software before. Read the blog post. See the requires() reference for more information Conan Center has stopped receiving updates for Conan 1. Upon every execution of Conan, all the relevant environment variables and paths from these build_requires (for example JAVA_HOME or MSYS_ROOT) become set and available to Conan, but only for the scope of the current Conan operation. Use it only when it is absolutely necessary that the We have added a new --require-override argument to define dependency overrides directly on the command line. X was introducing some issues with the automatic force/override of gmp/version, introducing a direct dependency to gmp/version that could have side effects. --filter = requires # --lockfile=conan. I think in this case this is an inconsistency in recipes in conan-center-index, and recipes there should be updated to use the same protobuf/3. Only the dependencies declared using the requires attribute or inside the requirements() method will be considered, build_requires don’t affect the package ID. This trait only exists at the time of defining a requires, but it will not exist as an actual requires once the Hi @realbogart. It’s important to check the Migration Guidelines I was thinking build_requires were 'required for build' and a requires was to indicate required for build & use. I'm testing my new library on windows and I want to make sure it also builds with MSVC. This way the first entry in the PATH variable will be /other/path but the PATH values declared in the requirements of the project will be appended at the end using the system path separator. We are actively working to finalize the Conan 2. Maybe also openssl/1 is a bad case, because it is not a good candidate for version ranges, at least with Conan 1 (Conan 2.

In case you do not have Ninja installed in your system, you can use the Ninja Conan package in your profile (default or custom) by adding tool-requires. Only default_options can be overriden. Sign in We'll work around this by making the use of build_requires() consistent for all packages (i. 0 test framework library that depends (normal require) on zlib/1. That means, their value is fixed, and cannot be overriden/defined from downstream consumers. In order to avoid collisions and conflicts, follow these rules: Public attributes and methods, like build(), self. requires with override=True appears to work. graph_lock import GraphLockFile from conans. 1 and then pkg/1. 6 gcc: 8. That is the key to I used conan 1. Properties of build requirements The behavior of build_requires is the I have a special problem. 60 <1. If you want to override libffi, you need to declare a dependency on it with self. 0 package will contain 2 different tool-requires to both gcc/1. So is there a way to specify required packages conditionally in For simple cases the attribute syntax can be enough, like tool_requires = "cmake/3. 0. But I have a runtime issue, my project need to be build on '/MD' but Conan still compile my requirement on '/MT'. 16 introduced a feature that allows to override any setting for a specific conan package in your dependencies graph. #11209. , my_folder/conanfile. Conan 1. Tool requires packages¶ In the “ Using build tools as Conan packages ” section we learned how to use a tool require to build (or help building) our project or Conan package. 0 package, using matrix/1. [bug] In some situations, Conan requires you to override a package when it is already overridden #12274. The unit tests in test_package depends on a gtest package, so I need to switch during the build of the test_package to the correct version. 0 # --lockfile=conan. Please, do not abuse Thanks @uilianries!. This may conan create <package> --<param>, but it would be better if it was written in the recipe itself. 0, a normal library, that test_requires("gtest/1. This is fairly uncommon, as because the context matches, they overwrite the previous build requirements so tool4/1. 17 usage: conan lock create [-h] [-v [V]] [--name NAME] [--version VERSION] [--user USER] [--channel CHANNEL] [--requires REQUIRES] [--tool-requires TOOL_REQUIRES] [-b BUILD] [-r REMOTE | -nr] [-u] [-pr PROFILE] [-pr:b PROFILE_BUILD] [-pr:h PROFILE_HOST] [-pr:a PROFILE_ALL Definitely, build_requires do not participate in the "product" graph. Alternate to private dependency in Conan 2. 8. We use a lot of recipes from conan-center, but we need to keep them stable over some years, so we copy them to a on local repository (the change rate is a way to high on the original side). 0 allows version ranges better over openssl/1). A new https://center2. 0 is the version, usually matching the one of the packaged project/library. 2 package, it will be used instead of the remote one, even if the remote one is newer. py, like: Methods source() Method used to retrieve the source code from any other external origin like github using $ git clone or just a regular download. It will still not allow to override that dependency, if you declare it invisible for your consumers, then your consumers cannot override it. txt, conan install will logically fail with the Error Missing prebuilt package on Linux. The only exception would be testing libraries and frameworks, as long as the tests are not A new https://center2. But in conanfile. – John. py and it should be placed next to it. So when the upstream is updated and Hi @SzBosch. It is free and open-source, works on all platforms (Windows, Linux, OSX, FreeBSD, Solaris, etc. Bugfix: conanfile. 0 features a new strategy for defining, detecting, and handling invalid configurations. Before moving on, we need to introduce what a Conan package reference is and which are its components. This is very good, as it solves many problems, but sometimes you need to be able to resolve reported conflicts and this seems The first important point is the build_requirements() method, that does a tool_requires() to both binaries, but defining run=False and options={"myoption": value} traits. At the moment, an override can only be expressed in python conanfile. 1. cmake: containing the translation of Conan settings to CMake variables. Provide details and share your research! But avoid . This is basically impossible to implement in git repos. set_name() and set_version() might be used. 27 版本的翻译，后期会加上作者的理解，适当更改文档，使其更通用。 conan 中文文档 v1. To give a concrete example, let's say we have a project P that requires libraries A and B. lock explicit. 24. If I do conan install <package> with my hands, then it will install it, even if it was installed before. We'll work around this by making the use of build_requires() consistent for all packages (i. . yml file is customized to add new configurations to the settings. Version ranges resolution in Conan is not doing a full compatible range evaluation, it is a greedy algorithm in which the consumers (we call it root of the graph) always has precedence. #11307. This document is for an outdated Conan version. 2 to 2. py, they should match) optional arguments: -h, --help show this help message and exit -j JSON, --json JSON json file To address these needs Conan implements build_requires. With the -s parameters you can define:. This feature affects only to regular requires, not to tool_requires or You signed in with another tab or window. A quick reminder about Conan package reference. A is self contained, but B depends on A for its The force and override traits to solve conflicts are not recommended as a general versioning solution, just as a temporary workaround to solve a version conflict. cmake file that was created when running conan install, you can see there that there are many CMake variables declared. build_type, then, adding it explicitly to . Another example in which we may want to try some new zlib alpha features: we could replace the zlib requirement with one from another user or channel. 39. We don't have a mechanism to block the overrides. This doesn't seem a bug, but it is this way by design. This is very important: we are telling Conan that we actually don’t need to run anything from those packages. Just a quick note: When you are using configure() method, the "options" are being hardcoded. lock is implicit # creates the engine/1. 24 are starting to accept two profiles with command line arguments -pr:h /--profile:host and -pr:b /--profile:build. First, explicit version updates and how to define versions of Conan. 5" and test_requires = "gtest/1. See the requires() reference for more information As tool_requires are not visible, they don’t define headers or libraries, there is nothing that makes Conan identify those 2 tool_requires as conflicting. self. And gtest doesn't actually adhere to semver but expects Its actually kinda lacking that conan has the capability to do so, (when you override some dependency in the package upstream ) but doesnt expose it to the users. Separating build requires and requires is the good approach. For example CONAN_INCLUDE_DIRS_ZLIB, that defines the include path to the zlib headers, When using version ranges, versions in the cache are preferred over remote ones, so if you have a local pkg/1. txt file is a simplified version of conanfile. io has 31 repositories available. 0 Python version: 3. To solve the conflict, then the explicit override=True (when there is no direct dependency to that resolved package version) or So conan info succeeds without raising a conflict and conan create does conflict? Yes, for conan v1. X it is not possible to override transitive dependencies of tool_requires (or build_requires, because they are kind of invisible to the consumer). py file, can be handy if the source code is not under version control. Limitations . DLL in windows, . . 0:INVALI Hi Is it possible to override build requirements? I'm trying to use proj/9. Packages can be overwritten, so it is also OK to have packages like “nightly” or “weekly”, that are regenerated periodically. 0 added the --require-override argument. However, some of them depend on another library. In the end, what I want to see, is weather I can have somewhat semi-automated propagation of upstream dependencies to downstream consumers. This is also less deterministic, and puts the control on the package creator side, instead of the consumer (version ranges are controlled by the We are planning to set up conan repositories for our C++ codes.
