Unresolved externals error installing pyAudio on win64 #11

I followed the process https://github.com/intxcc/pyaudio_portaudio#microsoft-visual-studio-2017. After successfully building portaudio, I got file pyaudio\portaudio-v19\build\msvc\x64\Release\portaudio.lib. Then I ran python.exe .\setup.py install --static-link in powershell as administrator, but got errors bellow:

Seems that there is something wrong with the static links.

Sorry, it was caused by my python. I reinstalled a 64-bit python and the problem was fixed.

Alright, happy that you figured it out! :)
