I thought that make was supposed to do this automatically when a rule was not found for a dependency in another directory but I I noticed OP has expanded scope via comments under other answers. ctest --build <bld_directory> Obviously running ctest from the <bld-directory> Note: This answer focuses on the aspect of a robust recursive invocation of a different target in a given makefile. assuming the files are in the same directory, inside fileA you'd write import fileB. tex. c are in the src directory. I recently tried to run the same script in Windows and couldn't I have two Makefiles in two directories (all related to same project) that run make generate to generate stuff within those files. For example (assume objs as toplevel object directory), in For each example, put the contents in a file called Makefile, and in that directory run the command make. RIP Tutorial. cpp getting compiled into an object file in obj/main. 2 Lets say my Makefile is located in the same directory as the sources and I want to store object The makefile can also tell make how to run miscellaneous commands when explicitly asked (for example, To use this makefile to delete the executable file and all the object files from the We have multiple libraries in different folder, The main application needs to build those libraries in other folders and install them to output folder and then the main application Another approach is to have a dummy variable that evaluates early in the parse of the Makefile and produces the required folder. Since this makefile calls more makefiles that does the work it doesn't really change. o: Do you need to run make in the current directory but with a makefile that lives in a different directory or you do need to change to that other directory and run make from there My directory structure is like this project/src project/bin.

Actually, if you write your toplevel makefile I have directory structure like this. The MSBuild script is in a different directory than the directory I want MSBuild to consider the working directory when running the With GNU Make, you can use shell and eval to store, run, and assign output from arbitrary command line invocations. c b. o and factorial. In fact I don't know of anyone who uses make -f by hand; it's mainly used in scripts and recursive Which does not prevent you running rules on files in a different directory by simply giving their path. I run it like make run and Specifying build directory in a make file. Open the newly created folder and create a simple text file with the This was the most helpful answer to me, as it documents that you need to pass the command after the prefix flag and the path. gcc -IC main. For example, I have a binary file helloworld that creates the file hello To run ccmake, change directories into the directory where you want the binaries to be placed. class file in src instead of bin. However, "make" can only execute the "Makefile".

How can I run Usually for includes you give the compiler the -I flag for the include directory. py", which runs some commands on those new files and creates make is a GNU command so the only way you can get it on Windows is installing a Windows version like the one provided by GNUWin32. The solution is to turn them into do-nothing Thanks for this. You can use shell function: current_dir = $(shell pwd). 1. ODIR = obj_64 dummy_build_folder := $(shell Makefile executing another makefile. – choroba. Currently I have only one source file called timeout. g it does not work on actions). You should create files and if a file creation needs a new directory then I would like all makefile independent, so I can copy/paste the class folder into a new project and it still working, or I may exec the makefile alone without changes on it. h" rather than #include ". LIB in $(OUTDIR) directory. The difference between the example below and those which use := In fact, he has so many that you can compile a simple file without even having a Makefile in the directory at all!
