AMPL Installation Wizard
Here are instructions to install AMPL-Gurobi on Linux:
- Extract the contents of the supplied AMPL-Gurobi file. Extraction is done with the following command:
tar xvfz amplgurobi11.0.3_linux64.tar.gz
The file name should be adjusted to reflect the actual archive file. Extraction will produce a subdirectory calledampl
, which contains the AMPL-Gurobi software. - Choose a destination directory. We recommend
/usr/local/bin
, but other directories will work as well. Copy the extracted files inside theampl
subdirectory to the destination directory. - 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
Note that you do not need to update LD_LIBRARY_PATH if you previously installed the standalone Gurobi Optimizer and set LD_LIBRARY_PATH during that process. - You will need a license key for AMPL - even if you already have a license key for the standalone Gurobi Optimizer. To get system information needed for a license key, 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.
