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[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.

version 9.2 did not build ...

got tons of errors:

Further info: https://github.com/google/or-tools/issues/2434#issuecomment-817126196

I've updated to v8.1 in b62a6cbdb46d

I've updated to v8.0 and added MadTux's suggestion in b6b5cf447d0d.

Could you add something like pacman -Qi cplex &> /dev/null && echo 'UNIX_CPLEX_DIR = /usr/lib' >> Makefile.local to build() please?

So that CPLEX can be used out of the box when it is installed.

EDIT: This would go between make third_party and make python according to the OR-Tools docs.

Thanks mcol, added in cdf6e5b20c97

Hey, this needs git as a makedepend btw :)

flipflop97: thanks for bringing this to my attention, I've added it to makedepends. v7.7 was released today and I've also updated the package to reflect that

Hi, it seems to require python-pip as makedepend. Can you add that?

FirefighterBlu3: looks like python-wheel was missing in makedepends, which I've now added.

In other news, I've updated to v7.6 which was released today.

why don't naming it python-ortools ? like the pypi package ? https://pypi.org/project/ortools/

I took maintenance of the package after it was orphaned, but it might be related to the repo being called or-tools on GitHub. If there's a way to rename it easily let me know.

I've updated the package to v7.5.

why don't naming it python-ortools ? like the pypi package ? https://pypi.org/project/ortools/

Python 3.8 support will arrive with the next release.

• Updated the package to build OR Tools 7.3
• Now, you get the same installation you would get if you installed it with pip
• Relaxed Python version requirements to Python >= 3.5. Python 2.7 is being sunset so I haven't added it
• Added a dependency on python-protobuf since the wheel file specifies it

The version limitation of the python dependency seems to be wrong. According to the documentation, the requirement is Python >=3.6 or Python >= 2.7.

Documentation: https://developers.google.com/optimization/install/python/linux

Otherwise, thanks for maintaining the package!

During installation, I noticed that the following packages are required for installation: wget and lsb-release
