Description Mitch Watrous 2011-03-18 17:26:48 EDT
If you do build the non-static (shared dynamic) version of ns-3, all of the tests in test.py pass.

But, if you do

    /waf configure --enable-static


    /waf configure --enable-static -d release

all of the Python examples fail:

    FAIL: Example examples/routing/simple-routing-ping6.py
    FAIL: Example examples/wireless/wifi-ap.py
    FAIL: Example examples/wireless/mixed-wireless.py
    FAIL: Example examples/tutorial/first.py
    FAIL: Example src/bridge/examples/csma-bridge.py

I think the reason is that I changed the wscript files to make the bindings be a static library. Before, they were always being created as shared libraries.

To be specific, I added to following to bindings/python/wscript:

        if bld.env['ENABLE_STATIC_NS3']:
            features = 'cxx cstaticlib pyext'
            features = 'cxx cshlib pyext'
        if env['ENABLE_PYTHON_PCH']:
            features += ' pch'

I also added following to wscript:

    if env['ENABLE_STATIC_NS3']:
        if sys.platform == 'darwin':
            env.STATICLIB_MARKER = '-Wl,-all_load'
            env.STATICLIB_MARKER = '-Wl,--whole-archive,-Bstatic'
            env.SHLIB_MARKER = '-Wl,-Bdynamic,--no-whole-archive'

Of course, Python bindings have to be dynamic libraries, period.
