Too many issues will kill our team's development velocity, drastically.
Make sure you have checked all steps below.

Prerequisite

• Make sure your problem is not listed in the common build problems.
• Make sure no duplicated issue has already been reported in the pyenv issues. You should look for closed issues, too.
• Make sure you are not asking us to help solving your specific issue.
  • GitHub issues is opened mainly for development purposes. If you want to ask someone to help solving your problem, go to some community site like Gitter, StackOverflow, etc.
• Make sure your problem is not derived from packaging (e.g. Homebrew).
  • Please refer to the package documentation for the installation issues, etc.
• Make sure your problem is not derived from plugins.
  • This repository is maintaining pyenv and the default python-build plugin only. Please refrain from reporting issues of other plugins here.

Description

• Platform information (e.g. Ubuntu Linux 16.04): macOS 12.4 (21F79)
• OS architecture (e.g. amd64): arm64
• pyenv version: 2.3.1
• Python version: 3.10.3
• C Compiler information (e.g. gcc 7.3): Apple clang version 13.1.6 (clang-1316.0.21.2.5)
• Please attach the debug trace of the failing command as a gist:
  • Run env PYENV_DEBUG=1 <faulty command> 2>&1 | tee trace.log and attach trace.log. E.g. if you have a problem with installing Python, run env PYENV_DEBUG=1 pyenv install -v <version> 2>&1 | tee trace.log (note the -v option to pyenv install).

Python Autoconf scripts can fail on M1 Macs but not Intel Macs and it appears to be related to gettext being installed by Homebrew in the /opt/homebrew directory instead of /opt/local.

Interestingly, commenting out these lines from the use_homebrew method in python-build appears to resolve the issue.

This works on an Intel Mac:

pyenv install 3.10.3
pyenv shell 3.10.3

cat > test.c <<EOF
#include <Python.h>

int main() {
  Py_Initialize();
}
EOF
gcc test.c $(python-config --cflags --ldflags --embed)

The result on an M1 Mac:

ld: library not found for -lintl
clang: error: linker command failed with exit code 1 (use -v to see invocation)

This works on an M1 Mac:

gcc test.c -L/opt/homebrew/opt/gettext/lib $(python-config --cflags --ldflags --embed)

This works on an M1 Mac after commenting out use_homebrew (lines 1328-1335 in /opt/homebrew/Cellar/pyenv/2.3.1/plugins/python-build/bin/python-build):

pyenv install 3.10.3
gcc test.c $(python-config --cflags --ldflags --embed)

Without use_homebrew:

otool -L ~/.pyenv/versions/3.10.3/bin/python
/Users/dave/.pyenv/versions/3.10.3/bin/python:

	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1311.100.3)

With use_homebrew:

otool -L ~/.pyenv/versions/3.10.3/bin/python
