Hi @iyabchen, thanks for your reply. I just did a succesfull install of pyicu==2.6.0 on a mint machine, by making sure its setup.py (which attempts to use the deprecated icu-config, but falls back to pkg-config) finds brew's keg-only icu pkgconfig. No more manual setting of compiler flags :)

I've updated the gist with this simplification, and also added brew install robsalasco/libpostal/libpostal.

Just ran into this myself and creating a new virtualenv with pyenv did the trick as well, didn't have to reinstall pkg-config or icu4c after having installed with homebrew.

I am having no end of trouble getting postal installed on an M1 Mac running OX 13.1 (Ventura). I have installed and uninstalled lib postal and the BREW command above seems to work flawlessly. However, in every install, I'm getting errors building the wheel. I've tried using the --use-pep517 argument and get the same result.

Hi 👋

This looks weird to me (don't understand why there would be a backtick (`) in that line for instance, also the pip install is weird 🤔

clang -Wsign-compare -Wunreachable-code -fno-common -dynamic -DNDEBUG -g -fwrapv -O3 -Wall -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX13.sdk -I/Users/lovejodh/libpostal/include -L/Users/lovejodh/libpostal/lib` pip install postal -I/usr/local/include -I/opt/homebrew/opt/[email protected]/Frameworks/Python.framework/Versions/3.11/include/python3.11 -c postal/pyexpand.c -o build/temp.macosx-13-arm64-cpython-311/postal/pyexpand.o -std=c99
clang: error: no such file or directory: 'pip'
clang: error: no such file or directory: 'install'

I can suggest running pip install -U pip setuptools wheel before running pip install postal, but doubt that it'll help. There are also differences in how you installed Python (I see yours is clang based but you can also compile CPython with gcc). I can recommend pyenv, see https://github.com/ddelange/new-mac-setup.

I've ported this gist to a Dockerfile which is ubuntu based.

A 'simple' pip install should be enough also on newer Macs (I'm on 10.15 so can't judge though), because either way, their setup.py is completely platform-agnostic.

Good luck!

Well, I figured it out. I was finally able to get the installer to see the .h file.

CFLAGS="-I/opt/homebrew/Cellar/libpostal/HEAD-8f2066b/include" LDFLAGS="-L/opt/homebrew/Cellar/libpostal/HEAD-8f2066b/lib" pip install postal

If you run into this, note that the include contains the directory name. So fi you set a CFLAG or a symlink that includes the directory name, it's going to miss it.
#include <libpostal/libpostal.h>
^~~~~~~~~~~~~~~~~~~~~~~

Awesome, thanks for reporting back!

Thank you SO much for responding @ddelange. I still can't get the postal scrubbing to work in scrubadub.py, but that's a problem for another day. It's not because it can't find libpostal, at least. The likelihood of there being postal data in this repository is nil, so I'm going to leave it for now.
