Generally, there would not be any big difference between compiled dll by msvc and mingw-w64. To further debug your issue, some information is needed.
* Can you provide any debug output or error messages given by that program? * May you provide a simple, minimal code and procedure to reproduce the issue exactly? * Also provide the system environment, cygwin or msys2 versions (if using), compiler and python versions etc. _______________________________________________ Mingw-w64-public mailing list Mingw-w64-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
