can not find the cpp_mstar

when I cd into the od_mstar3 folder, and use the terminal to run 'python3 setup.py build_ext --inplace', I can't find any new file, even the cpp_mstar file.

And the setup.py in od_mstar3 can not run until using terminal.

I want to know how to obtain the cpp_mstar file, there is no build file in od_mstar3
