Installation error on Windows

[VictorWictor]

I was able to successfully install wolfcrypt on Ubuntu (WSL) with pip install wolfcrypt, but I am getting following error when I try installing it on Windows.

I built the source distribution with python setup.py sdist which cloned and built wolfssl in lib\wolfssl directory. Then I get following error output when I try installing it with pip:

Seems like there are some macro conflicts that is causing syntax error and cascade into other errors. Following is the automatically generated user_settings.h that was in the build directory.

Hi @VictorWictor ,
I followed the same process as you and encountered the same problem. Could you please verify PR #71 fixes this?
Thanks,
Mattia (wolfSSL)

@mattia-moffa Yes, wolfcrypt now successfully installs. Thank you very much!
