Re: Problems building Python lib

Sorry -- Newbie here -- I don't know exactly what the 'latest CVS
state' is or how to get it.

I have been trying to build boost-python on Windows95 with
MSVC++6. I have boost 1.27 and activestate python 2.2.1 build 222.
I can get it to compile but the link fails.

Here is the linker message for the boost-example1:

Debug/hello.dll : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

hello.dll - 11 error(s), 0 warning(s)

Perhaps there is something simple I can do to fix this? Perhaps
there is something I need to include in the project to get the link
to work?

Can anyone help?

Thanks
