Hi all,

I am trying to build extension modules in Visual Studio.NET 2003.
I get the following link errors in debug mode, but there are no errors in release mode.

_viscoelastic error LNK2019: unresolved external symbol __imp__Py_FindMethod@12 referenced in function _veModelGlobalRayleigh_getattr@8
_viscoelastic error LNK2019: unresolved external symbol __imp__Py_InitModule4@20 referenced in function _init_viscoelastic@0

Hey,

I have got exactly same kind of error in cpp file using Microsoft Visual C++ compiler. Please make sure functions are defined before calling them and include all the libraries whatever need for coding, like- #include<string.h> needs for strcmp and strcpy function. Please review your code according to my points, hopefully it will works. If you need further help, please let me know.

Best regards,
