AMPL Installation Wizard

Here are instructions to add or upgrade Gurobi Solver to an existing AMPL installation on macOS:

  1. Determine the directory where AMPL is installed on your computer.
  2. Extract the contents of the supplied Gurobi Solver file. Extraction is done with the following command:
    tar xvfz amplgurobilink11.0.2_mac64.tar.gz
    
    The file name should be adjusted to reflect the actual archive file. Extraction will produce a subdirectory called ampl, which contains the Gurobi Solver software.
  3. Copy the extracted files inside the ampl subdirectory to the directory where AMPL is installed on your computer.
  4. To allow the AMPL-Gurobi executable files to be found when needed, ensure that the PATH environment variable includes the AMPL installation directory. Assuming that AMPL is installed in /usr/local/bin, users of the bash shell would add the following to their .bashrc files:
    export PATH="${PATH}:/usr/local/bin"
    
    And users of the csh shell would add the following to their .cshrc files:
    setenv PATH ${PATH}:/usr/local/bin
