[New-bugs-announce] [issue15772] Unresolved symbols in Windows 64-bit python

[Saul Spatz]

New submission from Saul Spatz:

In trying to build a SWING module on Windows with 64-bit python, I get the linker errors listed at the bottom of this message.

I have this problem with both python 2.7 and 3.2.  I have built the project without problems on Windows with 32-bit python, and a correspondent informs me that it cam be built on linux with 64-bit python.

I have listed the exports from python32.lib with dumpbin, and in every case, the symbol after the __imp__ appears in the library without a leading underscore. For example, for the first unresolved symbol, __imp__PyBytes_AsStringAndSize, I find that PyBytes_AsStringAndSize appears in the library.  Of 1074 exports in the library, 891 do not have leading underscores, and the remainder do.  In the 32-bit library, every export starts with an underscore.   

This is obviously related to issues 15165 and 14286, but I hope this additional information will help locate the trouble.  I am running windows 7 professional, and I installed python by downloading and running the installer with all the defaults.
