Describe your question, feature request, or bug.

The problem is a bug in the way the -arch flag is passed to clang.
Running 'LeaderfInstallCExtension' fails and generates the following output: Begin to compile C extension of Python3 ... running build running build_ext building 'fuzzyMatchC' extension clang -Wsign-compare -Wunreachable-code -fno-common -dynamic -DNDEBUG -g - fwrapv -O3 -Wall -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX 12.sdk -I/opt/homebrew/opt/binutils/include arm64 -I/opt/homebrew/opt/pyth [email protected]/Frameworks/Python.framework/Versions/3.11/include/python3.11 -c fu zzyMatch.c -o build/temp.macosx-12-arm64-cpython-311/fuzzyMatch.o clang: error: no such file or directory: 'arm64' error: command '/usr/bin/clang' failed with exit code 1 The problem was determined to be an incorrect passing of the arch flag. The -arch flag was passed with a trailing space. This resulted in a wrong invocation, where the command inculded this flag like this: 'arch ' arm64. See "Clang Error on Mac: No Such File or Directory: 'arm64' · Issue #3847 · Ericsson/codechecker" https://github.com/Ericsson/codechecker/issues/3847 The "[fix] is simply to pass arch flag correctly. See [fix] Pass arch flag correctly by vodorok · Pull Request #3854 · Ericsson/codechecker https://github.com/Ericsson/codechecker/issues/384

I believe I can create the C-Extension myself if I have access to the source-file (fuzzyMatch.c).

Steps to reproduce

Run :LeaderfInstallCExtension

Actual behaviour

See the next section.

Build fails with the output:

Running 'LeaderfInstallCExtension' fails and generates the following output: Begin to compile C extension of Python3 ... running build running build_ext building 'fuzzyMatchC' extension clang -Wsign-compare -Wunreachable-code -fno-common -dynamic -DNDEBUG -g - fwrapv -O3 -Wall -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX 12.sdk -I/opt/homebrew/opt/binutils/include arm64 -I/opt/homebrew/opt/pyth [email protected]/Frameworks/Python.framework/Versions/3.11/include/python3.11 -c fu zzyMatch.c -o build/temp.macosx-12-arm64-cpython-311/fuzzyMatch.o clang: error: no such file or directory: 'arm64'

Expected behaviour

The Python C Extension would be created.
