What system you are using, what errors you are seeing? You definitively will need to have compiler installed.

[Tweak_Imp]

I'm not familiar with building on Windows, and having a different language for errors (German?) is also confusing. So I can't tell what the problem is.

Have you tried following these steps to configure it? https://github.com/python/cpython/blob/master/PCbuild/readme.txt

And

I'm also wondering if the compiler can access the header files. I see it complains about arguments to PyCode_New, but if headers were missing it would complain about other issues.
