I do not know, but looks like is a packaging (upstream or downstream) issue around python-protobuf, is selecting a C++ version instead of Python version in CMake configuration.

I thought what python version should start with 5.: https://gitlab.archlinux.org/archlinux/packaging/packages/protobuf/-/issues/4

Hi everyone, this package is not ready yet. I asked to upstream if there exits some cmake configuration files for pybind11-abseil.

All, I've disowned the package as I'm not familiar enough with pulling in all the other dependencies via AUR. Please feel free to take ownership and make the necessary modifications.

Can't get this to build, it gets to the linking phase of a couple of targets and then just exits with code 2 with no information whatsoever. As others have pointed out, this package should be pulling in a lot more system dependencies anyway.

As a workaround to get flatcam to work, I've tried installing the wheel using a quick PKGBUILD: https://pastebin.com/yWSBVGx1 I'm sure there's much to improve about it, so I'm not putting it in the AUR at this point, but if anyone else needs something now this might help in a pinch.

Btw this is very badly configured. CMake should absolutely not be allowed to download sources; all sources should be declared in source=() array, and libraries that exist in Arch repo or on AUR should be used from those packages, not built from scratch.

It seems the current config leads to downloading the sources and building abseil-cpp, coin-or-cbc, coin-or-clp, coin-or-cgl, coin-or-coinutils, coin-or-osi, eigen, googletest, protobuf, pybind11, re2, scip and even zlib!

Plus, if Python venv is used during the build, it should be allowed to use system site packages, and the needed python libs should be declared in depends=() array so they get preinstalled via pacman. Current configuration is:

-- Python: Allow venv to use system site packages: OFF
-- Python: Fetch dependencies: ON

Build is broken:

-- Searching python module: "setuptools"
CMake Warning at cmake/python.cmake:89 (message):
  Can't find python module: "setuptools", install it using pip...

error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try 'pacman -S
    python-xyz', where xyz is the package you are trying to
    install.

    If you wish to install a non-Arch-packaged Python package,
    create a virtual environment using 'python -m venv path/to/venv'.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip.

    If you wish to install a non-Arch packaged Python application,
    it may be easiest to use 'pipx install xyz', which will manage a
    virtual environment for you. Make sure you have python-pipx
    installed via pacman.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of 
    breaking your Python installation or OS, by passing --break-system-packages.

P.S. Perhaps coin-or-clp should be in dependencies? Otherwise it is downloaded from Git and built by cmake.

There are a bunch of git dependencies pulled in by the build. For now I've been focused on getting the build working, but if you have ideas would be happy to apply a patch.

This would allow to use all CPU cores during build. Otherwise build is too slow.

Done!

Actually ended up reverting this, you should be setting MAKEFLAGS in your /etc/makepkg.conf so the build runs concurrently.

Hey all, I've updated to v9.8. There is a patch used to fix the build.

I've also adopted the python-mypy-protobuf dep and updated that to the latest version.

This would allow to use all CPU cores during build. Otherwise build is too slow.

Done!

Please change this line

cmake --build build

to this:

cmake --build build -j

This would allow to use all CPU cores during build. Otherwise build is too slow.
