Linker error on OSX 10.8 and Python 3 #162

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I’ve built PyV8 under OSX 10.8 and Python 3.3 and when I try to import PyV8, 
I receive the following error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "./PyV8.py", line 32, in <module>
    import _PyV8
ImportError: dlopen(./_PyV8.so, 2): Symbol not found: _PyClass_Type
  Referenced from: ./_PyV8.so
  Expected in: flat namespace
 in ./_PyV8.so

I had to update setup.py a little to make PyV8 compile under OSX:

include_dirs += [
    BOOST_HOME,
    os.path.join(PYTHON_HOME, 'include'),
    os.path.join(PYTHON_HOME, 'Headers'),
]

library_dirs += [
    os.path.join(BOOST_HOME, 'stage/lib'),
    os.path.join(PYTHON_HOME, 'lib'),
]

boost_lib_dir = os.path.join(BOOST_HOME, 'stage/lib')
if BOOST_STATIC_LINK:
    extra_link_args += [os.path.join(boost_lib_dir, "libboost_python-mt.a")]
else:
    libraries += boost_libs

I think the problem is that linker wasn’t able to find Python lib. I’ve 
checked my Python installation and found that `PYTHON_HOME/lib` contains the 
following files:

-rwxrwxr-x    1 root  admin  161904 Sep 29 12:21 libformw.5.dylib
lrwxr-xr-x    1 root  wheel      16 Feb  1 00:48 libformw.dylib -> 
libformw.5.dylib
-rwxrwxr-x    1 root  admin   84216 Sep 29 12:21 libmenuw.5.dylib

lrwxr-xr-x    1 root  wheel      17 Feb  1 00:48 libpanelw.dylib -> 
libpanelw.5.dylib
lrwxr-xr-x    1 root  wheel       9 Feb  1 00:48 libpython3.3.dylib -> ../Python
lrwxr-xr-x    1 root  wheel       9 Feb  1 00:48 libpython3.3m.dylib -> 
../Python
drwxrwxr-x    5 root  admin     170 Sep 29 12:27 pkgconfig
drwxrwxr-x  191 root  admin    6494 Sep 29 12:27 python3.3

so I added `PYTHON_HOME/lib` to `library_dirs` but still no luck.

Can you help me with proper config?

Please ensure your PyV8 linked with the right boost and python version, because 
Python 3.3 seems doesn't have the _PyClass_Type symbol
