Summary: COIN-OR Cut Generation Library (Cgl)

Development: https://github.com/coin-or/Cgl

The COIN-OR Cut Generation Library (Cgl) is a collection of cut generators that can be used with other COIN-OR packages that make use of cuts, such as, among others, the linear solver Clp or the mixed integer linear programming solvers Cbc or BCP. Cgl uses the abstract class OsiSolverInterface (see Osi) to use or communicate with a solver. It does not directly call a solver.

Installing coin-or-cgl

Installing coin-or-cgl from the conda-forge channel can be achieved by adding conda-forge to your channels with:

conda config --add channels conda-forge
conda config --set channel_priority strict

Once the conda-forge channel has been enabled, coin-or-cgl can be installed with conda:

conda install coin-or-cgl

or with mamba:

mamba install coin-or-cgl

It is possible to list all of the versions of coin-or-cgl available on your platform with conda:

conda search coin-or-cgl --channel conda-forge

or with mamba:

mamba search coin-or-cgl --channel conda-forge

Alternatively, mamba repoquery may provide more information:

# Search all versions available on your platform:
mamba repoquery search coin-or-cgl --channel conda-forge

# List packages depending on `coin-or-cgl`:
mamba repoquery whoneeds coin-or-cgl --channel conda-forge

# List dependencies of `coin-or-cgl`:
mamba repoquery depends coin-or-cgl --channel conda-forge

About conda-forge

conda-forge is a community-led conda channel of installable packages. In order to provide high-quality builds, the process has been automated into the conda-forge GitHub organization. The conda-forge organization contains one repository for each of the installable packages. Such a repository is known as a feedstock.

A feedstock is made up of a conda recipe (the instructions on what and how to build the package) and the necessary configurations for automatic building using freely available continuous integration services. Thanks to the awesome service provided by Azure, GitHub, CircleCI, AppVeyor, Drone, and TravisCI it is possible to build and upload installable packages to the conda-forge anaconda.org channel for Linux, Windows and OSX respectively.

To manage the continuous integration and simplify feedstock maintenance conda-smithy has been developed. Using the conda-forge.yml within this repository, it is possible to re-render all of this feedstock's supporting files (e.g. the CI configuration files) with conda smithy rerender.

For more information please check the conda-forge documentation.

Terminology

feedstock - the conda recipe (raw material), supporting scripts and CI configuration.

conda-smithy - the tool which helps orchestrate the feedstock. Its primary use is in the construction of the CI .yml files and simplify the management of many feedstocks.

conda-forge - the place where the feedstock and smithy live and work to produce the finished article (built conda distributions)

Updating coin-or-cgl-feedstock

If you would like to improve the coin-or-cgl recipe or build a new package version, please fork this repository and submit a PR. Upon submission, your changes will be run on the appropriate platforms to give the reviewer an opportunity to confirm that the changes result in a successful build. Once merged, the recipe will be re-built and uploaded automatically to the conda-forge channel, whereupon the built conda packages will be available for everybody to install and use from the conda-forge channel. Note that all branches in the conda-forge/coin-or-cgl-feedstock are immediately built and any created packages are uploaded, so PRs should be based on branches in forks and branches in the main repository should only be used to build distinct package versions.

In order to produce a uniquely identifiable distribution:

• If the version of a package is not being increased, please add or increase the build/number.
• If the version of a package is being increased, please remember to return the build/number back to 0.

coin-or-cgl-feedstock's Issues

Extra ncurses and readline dependency here?

Comment:

It seems that there is an extra dependency on readline and ncurses here.

That said, I think this is kinda tangled up in other coin-or- packages:

2022-09-09T02:32:34.8141014Z WARNING (coin-or-cgl): run-exports library package conda-forge::readline-8.1.2-h0f457ee_0 in requirements/run but it is not used (i.e. it is overdepending or perhaps statically linked? If that is what you want then add it to `build/ignore_run_exports`)
2022-09-09T02:32:34.8142501Z WARNING (coin-or-cgl): run-exports library package conda-forge::libzlib-1.2.12-h166bdaf_2 in requirements/run but it is not used (i.e. it is overdepending or perhaps statically linked? If that is what you want then add it to `build/ignore_run_exports`)
2022-09-09T02:32:34.8144183Z WARNING (coin-or-cgl): run-exports library package conda-forge::ncurses-6.3-h27087fc_1 in requirements/run but it is not used (i.e. it is overdepending or perhaps statically linked? If that is what you want then add it to `build/ignore_run_exports`)

Remove configure argument

Created based on conda-forge/staged-recipes#16147 (comment) for posterity.

---

The configure argument for specifying linking to blas and lapack should not be needed for any projects that don't have an explicit dependence on Blas and Lapack (cbc, cgl, osi).

It is assumed that the extra argument will just be ignored, but it might be confusing down the road to have it there.
