When embedding we must link with the python library AND USE -rdynamic OR -Wl,-export-dynamic OR -Xlinker -export-dynamic
to export ALL symbols from the Python library even if we do not use all of them.
This is needed when the embedded Python import modules to avoid undefined symbol errors.
But it doesn't work when embedding Python into a plug-in ( .so ) for an application.
I want to embed Python in a shared object which will be dynamically loaded by an application.
So when i build my share object, i link with the python library ( btw should i link with the .a or .so ? )
and i use the flag to export all symbols and Python is accessible from the application when my share object is loaded.
But i can't import Python modules ( example: import socket ), i get some undefined symbols errors.
I dont know exactly why.
Is it because the rdynamic/export-dynamic flags have no effect when building a shared object ?
Or is it a problem with my compiler: GCC 4.1.0, Linux 2.6.17 ?
Or is it because the application is loading my plug-in without the RTLD_GLOBAL flag ?
Or what ?
Please help :)
I found some people having the same problem but no workaround...
Thanks in advance.
