The latest OMC release for 16.04 LTS is also 1.9.7... For 12.04, we will not build anything anymore. There were too many changes to Ubuntu to bother supporting it. 14.04 we still build the release tag (release), maintenance branch (stable) and master branch (nightly). Use "stable" instead of "release" if you want to use 1.11.0 beta and release candidates (there is no 1.10.0 release).

Thanks, so that was easy, I am now using stable on 14.04 LTS.

Martin, may I ask one more questions:
I have a simulation that fails and is supposed to fail, but when I run it from a mos script like omc test_Failure.mos, omc returns code 0, so the CI build is marked as successful. What command do I have to add/edit? Something like getErrorString()?
Thanks

You need to check the output of the OMC commands and call exit(1) if you want an exit code. For example, this fails because loadString is commented out:

//loadString("model M end M;");getErrorString();

res:=simulate(M); getErrorString();

res:=res.resultFile;

if res=="" then

  exit(1);

end if;

Thanks once again, this works.
I guess I have to check the result file for every simulation, if I run multiple simulations like in the below script? Or is there a more elegant way?

loadFile("ExtraMath/package.mo");

loadFile("ExtraMathTest/package.mo");



res1:=simulate(ExtraMathTest.test_Exponential);

res2:=simulate(ExtraMathTest.test_Power);

res3:=simulate(ExtraMathTest.test_ErrorGamma);

res4:=simulate(ExtraMathTest.test_Success);

res5:=simulate(ExtraMathTest.test_Failure);



resF:=res4.resultFile;

if resF=="" then

  exit(1);

end if;

And, last not least: The CI script is downloading omc and the MSL from the OpenModelica server on every push (or if configured accordingly, on every pull request only). That might be noticeable traffic. Do you consider that acceptable?

We have a 100 Mbit/s connection and the OMC package is small. I would assume travis-ci fetches through an apt cacher (proxy) anyway (I do when building, and my build machine is connected to the same switch as the maching hosting the packages).
