Linking to Python import library in Visual Studio

问题:

I have a C++ application that has embedded Python. I'm building with Visual Studio 2005. When I try to link to python26.lib, I get a number of unresolved symbols, all of which begin with "__imp":

error LNK2019: unresolved external symbol __imp__Py_Initialize referenced in function _main

python26.lib is an import library (installed by the Python 2.6 installer). What do I have to do to resolve these symbols? They do exist in the import library (dumpbin /all shows them). Thanks.

回答1:

Looks like I was trying to link a 64-bit Python library to a 32-bit application. I wish the linker would tell me something other than "unresolved symbol." Linking to the 32-bit library fixes the problem.

回答2:

Try to include C:\WINDOWS\system32\python26.dll in your references. python26.lib contains the symbol names for the main DLL.
