Python build failed on MacOs Big Sur 11.2.1

[diegoos]

Hi.

I'm getting an error when try to install python 3.6.0 (I've tried other versions like 3.9.0, 3.6.10, 3.7...).

$ asdf install python 3.6.0

I'm using:

• MacOs Big Sur Version 11.2.1

• Clang 12.0.0

  $ clang --version
  Apple clang version 12.0.0 (clang-1200.0.32.29)
  Target: x86_64-apple-darwin20.3.0
  Thread model: posix
  InstalledDir: /Library/Developer/CommandLineTools/usr/bin

• gcc

  $ gcc --version
  Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
  Apple clang version 12.0.0 (clang-1200.0.32.29)

  Thread model: posix
  InstalledDir: /Library/Developer/CommandLineTools/usr/bin

• Command Line Tools version: 12.4.0.0.1.1610135815

Until now I've tried to:

• Reinstall the xcode command line tools with:

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

• Tried to install with zlib and bzip2 from homebrew

brew reinstall zlib bzip2

export LDFLAGS="-L/usr/local/opt/zlib/lib -L/usr/local/opt/bzip2/lib"
export CPPFLAGS="-I/usr/local/opt/zlib/include -I/usr/local/opt/bzip2/include"

• Patch

export ASDF_PYTHON_PATCH_URL="https://github.com/python/cpython/commit/8ea6353.patch?full_index=1"
asdf install python 3.6.0

• Patch and homebrew together

brew reinstall zlib bzip2

export LDFLAGS="-L/usr/local/opt/zlib/lib -L/usr/local/opt/bzip2/lib"
export CPPFLAGS="-I/usr/local/opt/zlib/include -I/usr/local/opt/bzip2/include"
export ASDF_PYTHON_PATCH_URL="https://github.com/python/cpython/commit/8ea6353.patch?full_index=1"
asdf install python 3.6.0

• Update homebrew, asdf and asdf-python (🤷🏼‍♂️ )

Can someone help with any other alternative or way to fix this?
