after installing WinGW, i am trying to implement this example that user Slimane implemented.

and whenever i do python setup.py build_ext --inplace, it produces the following error:

running build_ext

I went over same questions with the same error title but non helped me, can anybody relate to this issue?

  • The important error is "cannot find -lpthread" – DavidW Mar 20 '18 at 20:14
  • please, do you know how to fix this"cannot find -lpthread"? –  Mar 20 '18 at 20:18
  • I mention it because it's the more useful error to search for. Hopefully the question I've linked should tell you, but I don't use MinGW myself, so can't test it – DavidW Mar 20 '18 at 20:19
  • downloading the packages provided in [Eclipse MinGW C++ cannot find -lpthread](https://stackoverflow.com/questions/39185248/eclipse-mingw-c-cannot-find-lpthread), hopefully it is what i am looking for. thanks –  Mar 20 '18 at 20:22
