We should probably try and find a place on the wiki to put this information. Are you use that we're statically linking libpython2.7 and it's not just that gcc is looking for it at compile time?
Put another way, which one of these options should it be added too? I don't see Uday trying to statically link it, so I'm guessing #1. http://www.gem5.org/Using_a_non-default_Python_installation Thanks, Ali On Feb 12, 2013, at 3:51 AM, Andreas Hansson <andreas.hans...@arm.com> wrote: > Hi everyone, > > I'm glad that sorted the problem.
