AMPL Installation Wizard
Here are instructions to add Gurobi Solver to an existing AMPL installation on macOS:
- Determine the directory where AMPL is installed on your computer.
- Extract the contents of the supplied Gurobi Solver file. Extraction is done with the following command:
tar xvfz amplgurobilink9.1.1_mac64.tar.gz
The file name should be adjusted to reflect the actual archive file. Extraction will produce a subdirectory calledampl
, which contains the Gurobi Solver software. - Copy the extracted files inside the
ampl
subdirectory to the directory where AMPL is installed on your computer. - 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="${PATH}:/usr/local/bin" export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/usr/local/bin"
And users of the csh shell would add the following to their .cshrc files:setenv PATH ${PATH}:/usr/local/bin setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:/usr/local/bin
If LD_LIBRARY_PATH is not already set, you would use the following instead:export LD_LIBRARY_PATH="/usr/local/bin"
orsetenv LD_LIBRARY_PATH /usr/local/bin
- Open a terminal prompt and type the command:
fingerprint -o fp.out
This will generate a fingerprint file namedfp.out
. To request your license key (after we have received your payment or a Gurobi sales representative has approved your request to evaluate AMPL), email thefp.out
file to license@gurobi.com. - When you receive your license key, simply copy the license key file to the installation directory or any other directory in your PATH.
- If you are configuring a floating license server for AMPL-Gurobi, please follow the additional instructions for ampl_lic.
