In Ubuntu Linux 11.04 (natty) I installed OpenModelica. It is not possible to simulate, though a check of the model in OMEdit is successful.
I installed from the "lucid nightly" repository. A previous attempt from "lucid stable" did not work - OMEdit did not run at all.
Is it  the right way that I use the "lucid" version?
Can you give me a hint what I should try to get things work?
Many thanks in advance!
