27.5. Where is SCons Searching for Libraries? the --debug=findlibs Option

To get some insight into what library names SCons is searching for, and in which directories it is searching, Use the --debug=findlibs option. Given the following input SConstruct file:

        env = Environment(LIBPATH = ['libs1', 'libs2'])
        env.Program('prog.c', LIBS=['foo', 'bar'])
    

And the libraries libfoo.a and libbar.a in libs1 and libs2, respectively, use of the --debug=findlibs option yields:

      % scons -Q --debug=findlibs
        findlibs: looking for 'libfoo.a' in 'libs1' ...
        findlibs: ... FOUND 'libfoo.a' in 'libs1'
        findlibs: looking for 'libfoo.so' in 'libs1' ...
        findlibs: looking for 'libfoo.so' in 'libs2' ...
        findlibs: looking for 'libbar.a' in 'libs1' ...
        findlibs: looking for 'libbar.a' in 'libs2' ...
        findlibs: ... FOUND 'libbar.a' in 'libs2'
        findlibs: looking for 'libbar.so' in 'libs1' ...
        findlibs: looking for 'libbar.so' in 'libs2' ...
      cc -o prog.o -c prog.c
      cc -o prog prog.o -Llibs1 -Llibs2 -lfoo -lbar
