Issue 32931: Python 3.70b1 specifies non-existent compiler gcc++ (original) (raw)

Compiling an external module in the 3.7.0b1 prerelease on macOS High Sierra failed for me because a compiler named "gcc++" was not found. As far as I can tell there is no such compiler in the current XCode release. I don't know if there ever was one. The culprit file is:

/Library/Frameworks/Python.framework//Versions/3.7/lib/python3.7/_sysconfigdata_m_darwin_darwin.py

The following patch fixed the problem for me:

38c38 < 'CXX': 'gcc++',

'CXX': 'g++', 484c484 < 'LDCXXSHARED': 'gcc++ -bundle -undefined dynamic_lookup',

'LDCXXSHARED': 'g++ -bundle -undefined dynamic_lookup',
