Linking against static library in specific path

Re: Linking against static library in specific path

I found the answer, I had to add extra_objects to the Extension call, like this:

setup(

name = 'ipcbus',

ext_modules=[

Extension("ipcbus",

sources=["ipcbus.pyx", "../lib/ipcbus/ipcbus_message.cpp"], # Note, you can link against a c++ library instead of including the source

include_dirs=["../lib/ipcbus"],

libraries = ["../lib/ipcbus.a",],

language="c++",

extra_objects=["../lib/libipcbus.a"],),

cmdclass = {'build_ext': build_ext},

)

I found the answer in Stackoverflow: http://stackoverflow.com/questions/2105508/wrap-c-lib-with-cython

Sorry for bothering you

I'm trying to wrap some existing C++ code which is compiled and bundled in static .a libraries.
I've followed the guide exposed at http://wiki.cython.org/WrappingCPlusPlus and I wrote down this

setup.py file:

from distutils.core import setup

from distutils.extension import Extension

from Cython.Distutils import build_ext

setup(

  name = 'ipcbus',

  ext_modules=[

   Extension("ipcbus",

   sources=["ipcbus.pyx", "../lib/ipcbus/ipcbus_message.cpp"], # Note, you can link against a c++ library instead of including the source

   include_dirs=["../lib/ipcbus"],

   libraries = ["../lib/ipcbus.a",],

   #extra_link_args = ["../lib/libipcbus.a",],

   language="c++"),

   ],

  cmdclass = {'build_ext': build_ext},

)

Am I getting something wrong? libipcbus.a is a static lib, and though it compiles fine, I get some undefined symbols errors.

The library, as the above text shows is located in ../lib/.

Thanks
