how to solve error "Assertion `0' failed" raised from parallel run on redhat7
Posted March 4, 2016 at 03:56 by donQi
After building OF2.4.0 on redhat 7, when launching the motorBike tutorial in parallel I was facing the following error:
SOLUTION : as explained here https://www.open-mpi.org/community/l...5/08/17812.php it was due to a conflict between libnl and libnl3.
Therefore as root I removed the libnl3 with the command
and the parallel run becomes possible:
Code:
snappyHexMesh: route/tc.c:973: rtnl_tc_register: Assertion `0' failed. snappyHexMesh:22793 terminated with signal 6 at PC=7f24c66715f7 SP=7fff5c4d65f8. Backtrace: snappyHexMesh: route/tc.c:973: rtnl_tc_register: Assertion `0' failed.
Therefore as root I removed the libnl3 with the command
Code:
rpm -e --nodeps "libnl3"
Code:
