how to build a project when Makefile is in subdirectory? [message #192119]

Hello everyone,

I'm kind of new to Eclipse and I am facing a problem with a project that I
imported from my CVS repository as a standard make c++ project (as the
tutorial explained). The project has a Makefile that I created, but it is
not in the root directory but on the src/ subdirectory. Now, when I try to
build the project, nothing happens of course because there is no Makefile
in the root directory. Is there a way to tell Eclipse to run make in a
subdirectory?

Thanks for your help.

Either:

- change the make command in Eclipse to make -C subdirectory
- add a makefile in the project root that invokes make in the subdirectory

I did it the first way and it works fine!
Do you have an example of a Makefile that calls other Makefiles in
subdirectories? I don't really understand how Makefiles work.
Thank you.

Here is a really simple example:

DIRS=sub-dir1 sub-dir2 sub-dir3

all::
@for i in ${DIRS}; \
do \
make -C $${i}; \
done

clean::
@for i in ${DIRS}; \
do \
make -C $${i} clean; \
done

If make is available on your system the documentation is probably
available too in info pages. Just call "info make" or use another
info browser.

Please note that Makefiles are not only useful for compilation but
also to create other files which have dependencies such as
documentation, ... So you should really learn it.

You can specify the build directory:
Goto project->properties->C/C++ Make Project->Build Location->Build
directory
Click the button Workspace below the text field. Select the subdirectory
where your Makefile resides.

This is a nice way to do it. The funny thing is that this option (build
directory) was hidden in the window that pops-up after
Project->Preferences. I had to resize that windows for that option to
appear. I'm using Eclipse 3.2.2 on an Ubuntu Linux platform. Is this a bug?

Thanks for helping.

simple one, this may work.

all:
./$(YOUSUBDIR)/make all

Make sure there is a tab, not spaces before command

I never had that problem. I am using Eclipse 3.2.2 on Gentoo with Sun JRE
1.5 (JRE 1.4 and 1.6 also work flawless).
