Question

I have made a SCons builder that takes a Makefile file as a source and calls it to generate “things”.

(Mainly it is a Makefile written by other libraries, so I don’t have to choice to replace it with SCons).

So far, it works well but now I’d like to make the scons -c work as well.

My MakefileCallBuilder only has a dummy target as its target so scons -c won’t really clean anything.

Is there a way of telling SCons that I want make clean or make distclean to be called upon cleaning ?

Answer 1

I have been pulling my hair out because of this exact problem. I finally created a solution that is kind of crude, but works. Here is the part of the SConstruct file which does cleaning:

import subprocess

...

# Call make to clean
if env.GetOption('clean'):
    subprocess.call(['make', 'clean'])  

Basically, since Scons does not offer any way to call make clean, I get it done via Python’s subprocess.call().
