[Bf-python] compile a native c extension for python with msvc 2013

[Michel Anders]

Solved: it helps if you compile for the x64 platform  (the example solution only contains win32 configurations and I think this choice not only affects the generated code but also the name mangling used to generate decorated names in the .dll, hence the linker errors)

 

I should’ve looked better :-/

 

BTW: the /export:initexample switch is wrong: there is no need to explicitly export anything (the PyMODINIT_FUNC macro takes care of that) and although the python docs state otherwise, the module initialization function should be called PyInit_xxxxxx (as it is in the ectuall example code) and NOT initxxxxxxx (as stated in the accompanying text).

 

Cheers,

Hi,

 

Did anyone have any luck in compiling the example_nt extension from the python source distribution w. msvc 2013?

 

I copied it into  lib\win64_vc12\python, opened the solution in msvc 2013 and after pointing the include directories and library directories o the ones in the same python lib it compiles ok but complains about not being able to find initexample although there is an /export:initexample defined in the properties. Anyone have a clue?

 

Cheers,

 

-- Michel.
