Hi all,
I scoured the eclipse bug database, the eclipse forums and the
linuxtool archives, and haven't seen anything on this. Looks like
ValgrindCommand.java can't read it's version number?
I can't launch Valgrind from CDT, I get an NPE:

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.
