compiling on snow leopard

[John]

after beating up my setup.py all afternoon, i finally got PyV8 to
compile on snow leopard.

I installed boost libraries in /opt/boost/lib, and copied libv8.dylib
to /usr/lib

when I run python, I have to set the DYLIB_LIBRARY_PATH environment
variable in order for the boost libraries to be found, so this is what
I have:

> DYLD_LIBRARY_PATH=/opt/boost/lib python
> Python 2.6.1
>>>> import PyV8
>Traceback (most recent call last):
> File "<stdin>", line 1, in <module>
> File "PyV8.py", line 8, in <module>
> import _PyV8
>ImportError: dlopen(/Library/Python/2.6/site-packages/_PyV8.so, 2): Symbol not found: __ZN2v88internal9Internals13kJSObjectTypeE
> Referenced from: /Library/Python/2.6/site-packages/_PyV8.so
> Expected in: flat namespace
> in /Library/Python/2.6/site-packages/_PyV8.so
>>>

i'm not sure what is causing it. Does anyone have any ideas?

It seems that you linked wrong v8 library, because
__ZN2v88internal9Internals13kJSObjectTypeE is a symbol for
v8::internal::internals::kJSObjectType.

I can't reproduce your issue, because I working on windows and linux
platform, but I think you should try to use static link and ensure
your library is OK

I had a similar problem on leopard. I turned out libboost_python was
linked to system python rather than my install.
You need to use "otool -L library" to find out what is linked, and
"install_name_tool -change" to fix.

Thanks for your advises

Could you do me a favor to write some comments and update the wiki
page about how to compile it on leopard?

Don't think I have permission.

FYI, I was getting this as well. Like Flier suggested, doing a static
compilation of v8 got it working (also as arch=x64)
