Making multiple projects with one makefile

[Norris, Nelson [LBRT/LNA]]

I am looking for assistance in creating a makefile that will navigate a tree of directories, and perform a build on each subdirectory.

 

Example:

 

main project - contains a high-level makefile, that builds each of the following sub-projects (contained in

    |             subdirectories under the main project, where the project makefile is executed)

        |--- controlBoard - contains a makefile for building it's code

        |--- displayBoard - contains a makefile for building it's code

        |--- serialOptionBoard - contains a makefile for building it's code

 

I have attempted to do this using the 'foreach' function, but it won't work with multiple subdirectories.

 

The main project makefile I created contains the following:

 

MAKEDIRS = controlBoard displayBoard serialOptionBoard

all:

    $(foreach dir, $(MAKEDIRS), $(MAKE) -C $(dir))

I expect it to go to the controlBoard directory, perform a make, then go to the displayBoard directory, perform a make, and finally go to the serialOptionBoard directory, and perform a make.

 

The response I get back from GNUmake is the following text:

 

gmake[1]: Entering directory `C:/_projects/mainProject'
gmake -C controlBoard  gmake -C displayBoard  gmake -C serialOptionBoard
gmake: Entering an unknown directory
gmake: Leaving an unknown directory
gmake[1]: Leaving directory `C:/_projects/mainProject'

Each of the subprojects builds correctly if I manually go to each subdirectory and invoke GNUmake.

 

 

 

Regards,
