[Scons-users] LoadableModule on Python OSX binding generates "PyThreadState_Get: no current thread"

[Marc Magrans de Abril]

Hi,

You were right! The following SConstruct file worked:
env = Environment()

env.Append( CXXFLAGS=['-Wall'])
env.Append( CPPPATH=
['../mylib/include','/opt/local/include','/usr/include/python2.7'])

env.Append( LIBPATH = ['/opt/local/lib','../mylib/lib'])
env.Append( LIBS = ['python2.7','boost_python','mylib'])

env.LoadableModule('lib/mybindings.so', 'src/mybindings.cpp')

Many thanks,
marc
