Compiling native extensions with Visual Studio 2012?

[Alec Taylor]

There have been various threads for MSVC 2010[1][2], but the most
recent thing I found for MSVC 2012 was [3]… from 6 months ago.

Basically I want to be able to compile bcrypt—and yes I should be
using Keccak—x64 binaries on Windows x64.

There are other packages also which I will benefit from, namely I
won't need to use the unofficial setup files and will finally be able
to use virtualenv.

So anyway, can I get an update on the status of MSVC 2010 and MSVC
2012 compatibility?

Thanks,

Alec Taylor

Besides the deep technicality of potential conflicts, two changes will allow you to compile your C extension. msvc9compiler.py is written only lookingfor VS2010, and even if you have vs2010 installed, it will still fail on Windows 7, Windows 8 with silly manifest errors.

The fix is simple:
In: Python27/Lib/distutils/msvc9compiler.py,
line#648 in definition of "link", before the call to "ld_args.append('/MANIFESTFILE:' + temp_manifest)",insert:
ld_args.append('/MANIFEST')

line#178 in the definition of "get_build_version", insert:
return 11.0
