Error when importing fiona on an M1 Mac. about fiona HOT 5 OPEN

@lucasbrightnight thanks for the report! I can't reproduce this on my M3 MBP, which has libpcre2 in /opt/homebrew/lib, from Homebrew, and also in /usr/lib, which must be from macOS or XCode, yes? Can you confirm that you have or haven't installed XCode and command line tools on your computer?

from fiona.

@sgillies, sure thing! As I understand it, homebrew installs to /usr/lib paths for intel chips uses whereas Apple M1 chips install to /opt/homebrew paths. I can confirm I have not installed XCode. I am using fish and bash for command line tools.

I can confirm I only have libprec2 installed in the /opt/homebrew file path and not the user/lib path.

@lucasbrightnight my memory is that Homebrew installed to /usr/local, not /usr. On my work MBP /usr/lib/libpcre2-8.0.dylib has the same timestamp as everything in /System/Library, which suggests that it's part of macOS. I see the same thing on my personal laptop. Certainly, the macOS wheels were built on a system where /usr/lib/libpcre2-8.0.dylib existed, otherwise the library would have been vendored into the wheel like libgdal and friends. I don't have an explanation for why the file is missing from your system.

Exactly the same issue here (also on an M1 mac)

from fiona.

I'm experiencing the issue as well on an M1 Mac running MacOS 12 and:

$ brew --version
Homebrew 4.3.3

$ brew info pcre2 | head -1
==> pcre2: stable 10.43 (bottled), HEAD

$ xcode-select --version
xcode-select version 2395.

$ gdal-config --version
3.9.0

and a Python virtual environment with Fiona installed as a wheel:

$ python3 --version
Python 3.11.9


$ pip show setuptools pip wheel fiona | grep -E "Name|Version"

Name: setuptools
Version: 70.0.0

Name: pip
Version: 24.0

Name: wheel
Version: 0.43.0

Name: fiona
Version: 1.9.6

I have nothing matching /usr/lib/*pcre*, but Homebrew does report that the pcre2 package provides a /opt/homebrew/Cellar/pcre2/10.43/lib/libpcre2-8.0.dylib:

$ brew list
/opt/homebrew/Cellar/pcre2/10.43/bin/pcre2-config
/opt/homebrew/Cellar/pcre2/10.43/bin/pcre2grep
/opt/homebrew/Cellar/pcre2/10.43/bin/pcre2test

/opt/homebrew/Cellar/pcre2/10.43/lib/libpcre2-8.0.dylib
/opt/homebrew/Cellar/pcre2/10.43/lib/libpcre2-posix.3.dylib

/opt/homebrew/Cellar/pcre2/10.43/lib/ (8 other files)
/opt/homebrew/Cellar/pcre2/10.43/share/doc/ (109 files)
/opt/homebrew/Cellar/pcre2/10.43/share/man/ (96 files)

It is linked in /opt/homebrew/lib/libpcre2-8.0.dylib. Reinstalling with --no-binary seems to have gotten me a working version of the package.

$ pip install fiona --no-binary fiona
