Looking at the stack trace, it seems like the Process object being created at ValgrindCommand.java:35 is coming back null. Are there any additional error messages in the Error Log view around the time this happens (maybe something mentioning RuntimeProcessFactory) ? If not, and given that this seems to be a local launch, I think something might be going wrong in the CommandLauncher class. The strange thing is that even the basic things like building a C/C++ project using make rely on this class. When you build your C/C++ project are there any errors at all in the error log view ? I don't think I've seen something like this before, but if the code is failing to create a Process object, we should give a better reason for why this happens. -- Roland Grunberg _______________________________________________ linuxtools-dev mailing list linuxtools-dev@eclipse.org https://dev.eclipse.org/mailman/listinfo/linuxtools-dev
