Running Python from C++ (VS2010, compiler v100)

Question

I have some code here that we used to use to call a Python script from our (very large) application. It worked fine when we used VS2008 (compiler v90), which is what the default version of python27 was compiled with.

In the last year we've upgraded our application to VS2010, and I was looking to update the Python-calling dll, thinking it would be a morning's work. Unfortunately, after wrestling with the linker and missing dlls for ages, most of my colleagues agree that our application and python27.dll are using incompatible versions of Windows CRT.

I thought it would be simple enough to find a version of python27.dll (or indeed another version would be fine) compiled with VS2010 (v100) - but I can't.

Is there a way to call a Python script from an application compiled in VS2010?

Answer 1

An answer may be: Download the python sources - compile a custom python.dll and link against that.

Answer 2

I have the same problem. The solution is indeed to build python from the sources. But there is a big drawback: all extra 3rd party python modules pre-build for Windows that you download from internet will not work! This is because all of those modules will be prebuild with VS 2008 and you get again in trouble with incompatible runtimes. The solution is that all such extra modules needs to be again rebuild from sources, but the task is not easy in all cases. The modules are ususally tested in VS2008 and you get a lot of troubles trying to run them with VS2010. I got this mostly with database connectors for MySQL, MSSQL and others.
