[macOS] ModuleNotFoundError: No module named 'encodings' when compiling with meson

[ben-xD]

I'm trying to build gstreamer locally with python 3.11 from uv. I've managed to build gstreamer locally with the homebrew python. I use python 3.11 because the gstreamer version im using has a dependency that relies on distutils, removed in python3.12.

I would like to use python by uv. I modified the steps by @samypr100 in #8966 (comment)

Reproducible steps

# Some dependencies of packages
brew install pkg-config ninja

git clone --branch 1.24 https://gitlab.freedesktop.org/gstreamer/gstreamer.git
pushd gstreamer

uv python install 3.11
uv venv -p 3.11
uv tool install 'git+https://github.com/bluss/sysconfigpatcher'
sysconfigpatcher $HOME/.local/share/uv/python/cpython-3.11*
uv pip install meson docutils

# Export PYTHON so the gstreamer build will use it
export PYTHON="$HOME:$(pwd)/.venv/bin/python"

# Build and install gstreamer
PKG_CONFIG_LIBDIR=/dev/null uv run meson setup build -Dwrap_mode=forcefallback -Dintrospection=enabled -Dpython=enabled -Dgst-plugins-good:lame=disabled -Dglib:tests=false -Dtests=disabled --prefix=$HOME/gstreamer

## FAILS HERE
uv run meson compile -C build

# Install to $HOME/gstreamer
uv run meson install -C build

Error

Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding
Python runtime state: core initialized
ModuleNotFoundError: No module named 'encodings'

Would you have any advice on this error?

I tried to repro, but hit a bump on meson setup with subprojects/gobject-introspection-1.74.0/meson.build:129:11: ERROR: Recursive include of subprojects: gstreamer => glib => gobject-introspection => glib.

My initial thoughts is that it's possible this is related to meson issues discussed as part of #7857 as meson doesn't work with build isolation. From a python meson setup I also expected to see /Users/user/repos/gstreamer/.venv or '$HOME/.local/share/uv/python/cpython-3.11* instead of /install.

Do you have a docker based reproduceable steps?

[ben-xD]

Apologies @samypr100, there are many things that can go wrong with the gstreamer stuff. Gstreamer currently has a broken main branch lol where there is a hard circular dependency... Please try on branch 1.24, that works for me. I've also updated my first messsage

git checkout 1.24

A docker setup wouldn't let me use brew, native macOS etc so I haven't tried to set that up.

About build isolation, setting -Dwrap_mode=forcefallback will not use any of the system libraries, and download everything. That allows the build to be a bit more isolated, but I do need to install some things (currently python including headers from brew, ninja, meson).

[samypr100]

Hmm, still not happy. Same error.

Re: build isolation, I meant Python PEP 517 build isolation, not meson's build isolation with respect to system libraries 😅

[ben-xD]

Sorry @samypr100, I believe you need to reset the subprojects and build folder. Try git clean -fXd build subprojects. You'll need to automatically download the dependencies again, but this should work.

[samypr100]

Could you maybe try building in a clean environment, e.g. via a ghcr.io/astral-sh/uv:debian docker container?

That's what I've been using (always pristine). I was able to get 1.24 branch to build, compile, and install after removing -Dwrap_mode=forcefallback to avoid the Recursive include issue. My patched uv python also had the right pkgconfig settings

# See: man pkg-config
prefix=/root/.local/share/uv/python/cpython-3.11.11-linux-x86_64-gnu
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: Python
Description: Build a C extension for Python
Requires:
Version: 3.11
Libs.private: -lpthread -ldl  -lutil
Libs:
Cflags: -I${includedir}/python3.11

[ben-xD]

I'm trying to build the macOS library rather than the linux one so I can load it on macOS without docker. Using a debian based docker image wouldn't be useful for me even if it works?

The recursive include shouldn't affect 1.24 - that might've happened because you didn't clean your macOS build (subprojects folder).

Removing forcefallback means you might be using system libraries instead. According to the gstreamer devs, force fallback is needed to enable gobject-introspection (something I need), so that's why I'm using forcefallback too 😅

[samypr100]

Does it work for you on debian just not on macOS?

Closing as stale, feel free to follow-up if you are having problems still.

It's not really relevant for me, I just always create virtual environments directly with uv. And I haven't seen such errors in any other situations.

[zanieb]

If we're to debug this further, I think we'll need an isolated, minimal reproduction in a Dockerfile.

@tkukushkin did you ensure that you're on the latest uv-managed Python version? uv self update && uv python install 3.13 --reinstall may be needed — we've added patches to help with module discovery in extension modules.

[tkukushkin]

@zanieb It doesn't help.

[samypr100]

@tkukushkin It might help if you can open a new separate issue following the steps from #9452

[zanieb]

Yeah we're happy to help, we just need a clear way to reproduce the problem so we can debug it. A container is best, since it's isolated from your system state.

[tkukushkin]

I fully agree, but I am not sure if this problem is relevant to linux and I am not sure that Darwin image will be helpful.
