Hi, I was able to get rid of the problem. Thanks for all your help and sorry for opening this ticket. What I believe to be the reason was a mismatch between gcc-linker or gcc-glibc installed. After rebuilding my toolchain entirely again (and not just gcc), I have been able to successfully run omnetpp.
