Can't install gcld3 on MacOS Ventura 13.2.1

[coreynorthcutt]

This looks to be extremely common, but after trying dozens of solutions, I'm still getting an error when installing gcld3.

First, here's the complete error output. I'm using the same recommended format that solved Issue #49 in this example:

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for gcld3
  Running setup.py clean for gcld3
Failed to build gcld3

The error with clang stands out: error: command '/usr/bin/clang' failed with exit code 1

This particular error appears no matter how I try to install cld. I get varying preceding error output, ie. if I try to pip install pycld3 instead... but the clang error is always there.

I've so far...

• done a brew update and brew upgrade.
• verified that Pip, Python, Protoc, Wheel, and Setuptools all have the latest versions.
• tried testing in a virtual environment (as some recommended in other threads).
• tried appending the --use-pep517 flag as the warning above suggests.
• tried setting a million different ENV variables in my local session (every thread seems to suggest something different)

pip install --global-option=build_ext --global-option="-I/opt/homebrew/Cellar/protobuf/21.12/include" --global-option="-L/opt/homebrew/Cellar/protobuf/21.12/lib" gcld3

also if you create conda environment it should work

Hey thank you for your solution -> I've mentioned the other solution but will copy it here for some lazy-guys like me. If that provided solution doesn't work for you try to install the gcld3/pycld3 package with these flags.(original author mentioned in the linked issue)

export LDFLAGS=-L/opt/homebrew/lib      
export CPPFLAGS=-I/opt/homebrew/include 
python -m pip install gcld3

Also, try using protobuf@21 as it's compatible with gcld3 because of the protoc being at 3.21

brew install protobuf@21

Then set these flags (preferably in your shell config):

export PATH="/opt/homebrew/opt/protobuf@21/bin:$PATH"
export CFLAGS='-I/opt/homebrew/opt/protobuf@21/include'
export LDFLAGS=-L/opt/homebrew/opt/protobuf@21/lib

Finally, try reinstalling the lib and see if that compiles now

I've placed 21.7 version of protoc in my path and still receiving this error in windows
