Known Problems

Issue: On some Linux systems, the IDE will not start; instead, an empty dialog titled "Omnetpp" appears after the splash screen, and it cannot be closed. The log file contains SWTError: XPCOM error -2147467262.

Solution: This is related to xulrunner (1.9 beta versions, possibly others); see https://bugs.eclipse.org/213194. xulrunner is part of Firefox; installing another version of Firefox (and making sure the wrong xulrunner version has been uninstalled!) should solve the problem.

Issue: Sometimes, after opening an existing project, C++ sources are not recognized properly by the IDE (file icons depict contoured "h" and "c" instead of solid ones).

Solution: Close and re-open the project. This is likely an issue in CDT; we are investigating it.

Issue: The simulation fingerprint can differ across machines or between valgrind and non-valgrind runs.

Solution: The value of the calculated fingerprint in a simulation is heavily dependent on the accuracy of the floating point arithmetic. There are differences between the floating point handling of AMD and Intel CPUs. By default GCC uses the i387 instruction set on intel processors and the SSE2 instruction set on AMD processors. Running under a processor emulator software like valgrind may also produce a different result. If your CPU supports SSE2 or later, add the -mfpmath=sse -msse2 options to CFLAGS_RELEASE and CFLAGS_DEBUG to get the same results on AMD, Intel and valgrind. See related bug report in valgrind: http://bugs.kde.org/show_bug.cgi?id=197915
