from wscript, it seems like --enable-static is only supported in linux. opt.add_option('--enable-static', help=('Compile NS-3 statically: works only on linux, without python'), maybe because of the gcc 4.2.1? I've looked into it but still have no idea where ar is coming from. Let me know if I can try something. I am not sure how to enable modules for bld.add_subdirs(list(all_modules))
you are right. We just tried this option in the newer buildbots, apparently it was never meant for darwin originally or may be it was supported for darwin later 401 elif env['CXX_NAME'] == 'gcc' and \ 402 (env['PLATFORM'].startswith('darwin') or \ 403 env['PLATFORM'].startswith('cygwin')): 404 conf.report_optional_feature("static", "Static build", True, '') 405 env['ENABLE_STATIC_NS3'] = True I will lower the priority of this bug , but will keep it open
Using the latest ns-3-dev, which contains RC2 but not RC3, if I try to enable one a singe module like this: ./waf configure -d optimized --disable-python --enable-static --enable-examples --enable-tests --with-pybindgen=pybindgen/ --enable-modules=core This works for these modules: core internet mpi bridge but fails for this module: emu So there is something special about the emu module.

There are no object files to pass to ar, so it fails.

I am going to try to make waf not build the emu library if emu is not enabled. Although this might introduce some coupling between the top level wscript and the emu module.
