[ThomasWaldmann]

Happens with pyinstaller 6.11.1 as well as with 6.12.0.

[ThomasWaldmann]

It's not just pyinstaller, python -m build showed the same issue.

[sothix]

@ThomasWaldmann I had similar problems.. try pip install -U setuptools

Also to get it to build on my end I had to patch cffi

pip install -U setuptools
pip download cffi
tar -zxf cffi-1.17.1.tar.gz
patch -p1 <<EOF

[ThomasWaldmann]

@sothix thanks for the hints. i worked around the cffi issue by using the system package.

It seems to build borg, but then it can't find borgstore (which is strange, because it logged that it successfully built it): https://github.com/borgbackup/borg/actions/runs/15093465312/job/42425051564?pr=8845#step:8:138

[sothix]

@ThomasWaldmann Just rebuilt using --system-site-packages but omitting upgrading pip setuptools build wheel and borg looks like it built correctly.

pacman -S --noconfirm git 
git clone https://github.com/borgbackup/borg.git
pacman -S --needed --noconfirm git mingw-w64-ucrt-x86_64-{toolchain,pkgconf,zstd,lz4,xxhash,openssl,rclone,python-msgpack,python-argon2_cffi,python-platformdirs,python,cython,python-setuptools,python-wheel,python-build,python-pkgconfig,python-packaging,python-pip,python-paramiko}
python -m venv --system-site-packages env
source ./env/bin/activate
cd borg
pip install .

however I get the following error:

C:\msys64\home\Soth\env\bin
λ borg.exe -r . repo-create --encryption=repokey-aes-ocb

same failed test problem?

[ThomasWaldmann]

the windows file urls with drive letter don’t work yet, see my unfinished other pr.

I'm retrying without upgrading these packages, let's see what github CI says...

I've tried several different builds some were failing initially but I think something has changed and now I cant get it to fail to build. Is the MSYS2 that is downloaded the latest?: pacman -Suy

@ThomasWaldmann found the problem. It was using the system pytest because of this line python -m venv --system-site-packages env. Should be able to change it back once cffi releases v1.17.2 which is due soon.

use this instead: python -m pytest -n4 --benchmark-skip -vv -rs -k "not remote"

[ThomasWaldmann]

Strange that it called the system pytest - shouldn't be the venv stuff be first in PATH / PYTHONPATH? I made the change and pushed, let's see if it works now!

Thanks for helping!
