Installed python-absl package to fulfil the dependencys. But building python-or-tools failed ...

I cannot find the dependency: absl-py

Hi, as arch has jumped from gcc 11 to gcc 12, or-tools are not able to get compiled. Here is patch for quick-fix:

Hi guys - I have received a bug when using python-or-tools 9.3-1, after trying to execute the bin-packing problem example in: https://developers.google.com/optimization/cp/channeling . When executing the lines:

solver = cp_model.CpSolver()
status = solver.Solve(model)

I received:

/usr/include/c++/11.2.0/bits/stl_vector.h:1063: std::vector<_Tp, _Alloc>::const_reference std::vector<_Tp, _Alloc>::operator const [with _Tp = operations_research::sat::Literal; _Alloc = std::allocator<operations_research::sat::Literal>; std::vector<_Tp, _Alloc>::const_reference = const operations_research::sat::Literal&; std::vector<_Tp, _Alloc>::size_type = long unsigned int]: Assertion '__n < this->size()' failed. [Finished in 0.5s with exit code -6]

My arch is updated and my Python is the 3.10.4 .

I checked ortools-9.2.9999.dist-info/METADATA and found dependencies on absl-py & python-numpy which have been added in ff45efd6fab7. Seems like python-mypy-protobuf is needed as makedepends so I've added that in 9507eb4a61fd. Pandas + matplotlib only seem to be necessary to run examples so I've added them as optdepends in abedd03e0e11.

My build failed with a make error. In my case it was just python-mypy-protobuf which was missing:

protoc-gen-mypy: program not found or is not executable
Please specify a program using absolute path or make sure the program is available in your PATH system variable
--mypy_out: protoc-gen-mypy: Plugin failed with status code 1.
make[2]: *** [CMakeFiles/Pyortools_proto.dir/build.make:89: python/ortools/constraint_solver/assignment_pb2.py] Error 1
make[1]: *** [CMakeFiles/Makefile2:2008: CMakeFiles/Pyortools_proto.dir/all] Error 2

New version 9.2-1 build is working fine for me now. Did not have the packages installed which are named as dependency by @kruzah .... Only python-numpy was installed (as dependency of cura)

Build misses several dependencies that cause the package to fail to build. Please add dependencies python-numpy, python-pandas, absl-py, and python-mypy-protobuf to PKGBUILD (I'm unsure which of these are runtime deps and which are make-only). Sourced from here

Hey all, sorry for the delay. This is fixed in 0ef1baa82d54.

Seems like the makefile method originally used no longer works, so the PKGBUILD now uses cmake directly as outlined here: https://github.com/google/or-tools/blob/stable/cmake/README.md

Let me know if you run into any other issues.

I'm getting "ERROR: A failure occured in build(). Aborting..." on 9.2-1, but I don't know why cause my terminal screen doesn't go back enough.
