How to embed Python 2.4 in C++ application using VS C++ 6.0?

Question

I get this linking error, using Python 2.4 and MS VC++ 6:

Linking...
testPyEmb.obj : error LNK2001: unresolved external symbol __imp__Py_Finalize
testPyEmb.obj : error LNK2001: unresolved external symbol __imp__PyErr_Occurred

testPyEmb.obj : error LNK2001: unresolved external symbol _fprintf
testPyEmb.obj : error LNK2001: unresolved external symbol __iob

Adding this to my source file did not help:

#undef _DEBUG

I modified pyconfig.h to disable debug mode and force use of python24.lib instead of python24_d.lib as shown here: http://tutorial.debashis.net/?p=57&cpage=1 Still, same error.

What could i be doing wrong?

Have you added *python24.lib* and its path to the linker options? — Praetorian, Apr 18 '13 at 23:15
Yeap, I added python24.lib and its path to the linker options. — A.R., Apr 19 '13 at 05:42

Since you say that you are linking against the .lib, it may be that you have installed the 64 bit version of Python, and are thus linking against 64-bit version of the .lib file, but your build configuration is (I suspect) 32 bit. Go to Configuration Manager and change it to 64 bit.

Hope this helps. Marius.

I changed my configuration to x64 and then the project could no longer link with MSVCP120.dll. – James Dec 17 '15 at 02:31
