Openmodelica in Ubuntu 10.04

Jun-14-10 20:19:05

I've installed Openmodelica in Ubuntu 10.04, and after doing the first User Guide examples, an error appears:

>> simulate(dcmotor,startTime=0.0,stopTime=10.0)
record SimulationResult
    resultFile = "Simulation failed.
Error: Error occured while flattening model dcmotor
"

Anybody knows about it?

Thanks,

Jose

Did you load MSL first?

loadModel(Modelica)

Make sure that the loadModel() and loadFile() commands both return true. Note that the testmodels is installed into /usr/share/doc/omc/testmodels/dcmotor.mo on Linux.

Many thanks, Sjoelund,

I tried again and it works!  I don't understand what I was wrong, I'm very sorry.
Have a good day,
Jose

I am trying to install openmodelica in Ubuntu 10.4.  I know I haven't tried everything (i.e. downloading the debs) but I am putting together a script to set up OM (and a raft of other apps) for students, and would prefer to use the managed update approach.

I followed the instructions here:
http://openmodelica.org/index.php/downl … load-linux

This is what my /etc/apt/sources.list looks like:

Code:

deb http://security.ubuntu.com/ubuntu lucid-security main restricted

deb-src http://security.ubuntu.com/ubuntu lucid-security main restricted

deb http://security.ubuntu.com/ubuntu lucid-security universe

deb-src http://security.ubuntu.com/ubuntu lucid-security universe

deb http://security.ubuntu.com/ubuntu lucid-security multiverse

deb-src http://security.ubuntu.com/ubuntu lucid-security multiverse

deb http://build.openmodelica.org/apt release contrib

I also ran:

Code:

wget -q http://build.openmodelica.org/apt/openmodelica.asc -O- | sudo apt-key add -

then I ran:

Code:

sudo apt-get install openmodelica

and saw:

Code:

Try updating and install again. I switched the makefile to use relative paths instead (I guess when I tested it on my machine, the files were already cached and never actually downloaded from server).

Tried again with --fix-missing, no dice (though i did get omlibrary, which suggests maybe a new build is being run?)

Bah, I'll fix the script and post an update when I get a hold of a Linux machine. It might be working now since I cleared the apt-ftparchive cache.

Works on my Ubuntu machine now. Let's hope my script won't rebuild packages that already exist and thus change checksums again...
