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
