[capi-sig] Problems linking python25.lib into my executable using MSVC2008 Express

[Jeremy Friesner]

Hi all,

Apologies if this is a common question, I googled for it and couldn't find any 
good answers.

I've got a C++ program that includes an embedded Python interpreter, and under 
Linux and MacOS/X everything works fine.  It's a Qt4-based program, so all I 
needed to do was add -lpython2.5 to the LIBS variable in my .pro file.

Now I'm trying to get the same program working under Windows, but when I get 
to the link stage I run into trouble.  I've compiled the Python 2.5 library 
using MSVC2008 Express (and the project files in the PCBuild8 sub-folder), 
but when I try to link my own app (adding python25.lib to my LIBS line, of 
course), I get the errors shown below.

I notice that I only get link errors about the global objects exported in the 
Python25.lib library (e.g. _PyList_Type)... I don't get any errors related to 
exported Python functions.  Is there something special I need to do in order 
to get MSVC2008's linker to resolved exported global objects?

Thanks,
Jeremy
