Cliff, that appears to be a java virtual machine call. This will be the java machine that the eclipse based RUVM application runs under.
I had issues with GTK2 libraries not installed correctly in the same context so i would read the documentation and confirm you have the correct packages installed.
Thanks for the response and you may be correct. I have installation documentation for Questasim, but I can’t find installation documentation for RUVM. I did the RUVM-install from the install-script and that seemed to go okay, but I don’t know anything about GTK2 libraries. Any pointers to related documentation would be appreciated.
