NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Enter your internal repository url

(this should look similar to https://community.chocolatey.org/api/v2)

4. Choose your deployment method:


choco upgrade glpk -y --source="'STEP 3 URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:


choco upgrade glpk -y --source="'STEP 3 URL'"
$exitCode = $LASTEXITCODE

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0
}

Exit $exitCode

Description

NOTE: The following text is an excerpt from the official website.

GLPK (GNU Linear Programming Kit)

The GLPK (GNU Linear Programming Kit) package is intended for solving large-scale linear programming (LP), mixed integer programming (MIP), and other related problems. It is a set of routines written in ANSI C and organized in the form of a callable library.

GLPK supports the GNU MathProg modeling language, which is a subset of the AMPL language.

The GLPK package includes the following main components:

  • primal and dual simplex methods
  • primal-dual interior-point method
  • branch-and-cut method
  • translator for GNU MathProg
  • application program interface (API)
  • stand-alone LP/MIP solver

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.

Version Downloads Last Updated Status

GLPK 4.65 (release date: Feb 16, 2018)

The following new API routines for LP/MIP preprocessing were
added:

  • glp_npp_alloc_wksp allocate the preprocessor workspace
  • glp_npp_load_prob load original problem instance
  • glp_npp_preprocess1 perform basic LP/MIP preprocessing
  • glp_npp_build_prob build resultant problem instance
  • glp_npp_postprocess postprocess solution to resultant problem
  • glp_npp_obtain_sol obtain solution to original problem
  • glp_npp_free_wksp free the preprocessor workspace

See doc/npp.txt for detailed description of these API routines.

A new, more robust implementation of locally valid simple cover
cuts was included in the MIP solver.

The API routine glp_init_iocp was changed to enable long-step
option of the dual simplex by default.
