[Numpy-discussion] Compilation failures in f2py

[Christopher Albert]

Hi Sam,

looks like the XCode command line tools containing standard headers are
either not installed or updated. Try xcode-select --install or manually
download them from https://developer.apple.com/download/more/ and maybe
uninstall/reinstall them in case updates don't work. Check with

find /Library/Developer/CommandLineTools/ -name _stdio.h

which should
give /Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include/_stdio.h
(besides possible older versions of MacOSX)

Best,

Chris
