Exception during compile command on Introduction/Ch1

[leothaud]

I built dynamatic from sources and installed its dependencies by following the readme. Then, I tried to use dynamatic on Ch1 of the Introduction example, but the compile command threw a GRBException. Do you know how to solve the problem? You can find below the complete trace of my dynamic session.

Hi, thank you for reporting the issue!

For now, I suggest to check out this link to properly configure gurobi before doing another clean build.

After setting up gurobi, you could run the command below. If everything is fine, you will see output like what we have below:

$ /opt/gurobi1003/linux64/bin/gurobi_cl
Set parameter Username
Set parameter LogFile to value "gurobi.log"
Academic license - for non-commercial use only - expires 20XX-XX-XXX
Using license file /opt/gurobi1003/linux64/gurobi.lic

Usage: gurobi_cl [--command]* [param=value]* filename
Type 'gurobi_cl --help' for more information.

I will add a section on the main README on how to configure gurobi.

Thank you. The problem was that I needed a gurobi license.
