Gurobi v12.0 missing symbols

[torressa]

Describe the bug

Known and reported missing symbols in shared library libgurobi120
The symbols for the C functions GRBloadenv and GRBemptyenv are missing from the shared libraries.

Until Gurobi release v12.0.1 where this will fixed, users can use versions Gurobi v11.0.3 and earlier with this package.

You can also use the temporary workaround described here:

I've created a fork of Python-MIP in which I've implemented the necessary changes:
https://github.com/venaturum/python-mip/tree/gurobi1200

If you are installing with pip then you can use the following command:

pip install git+https://github.com/venaturum/python-mip.git@gurobi1200

If you are using a package manager other than pip then I suspect there will be a way to ask it to install a package directly from the branch of a repository, but you will have to investigate.

Note: this is valid for Gurobi 12.0.0 only! Once Gurobi 12.0.1 is released you should be able to resume using the current Python-MIP release.
