I see, I'm running: Ubuntu 13.04 (GNU/Linux 3.8.0-19-generic i686) Linux node0 3.5.0-43-highbank #66-Ubuntu SMP Tue Oct 22 03:54:35 UTC 2013 armv7l armv7l armv7l GNU/Linux gcc (Ubuntu/Linaro 4.7.2-2ubuntu1) 4.7.2 javac 1.7.0_25
Thank you for the information, I'll have a look at that. /Christoffer 2013/11/15 Ralph Castain <r...@open-mpi.org> > I can't replicate these problems - I tried both the current trunk and v1.7 > branches.
