Hi all,
After I compile LIGGGHTS with make auto command and copy the lmp_auto into example/chute_wear, the mpi process had a segmentation fault which is :
[yjin6-Precision-5820-Tower:01114] *** Process received signal ***

Actually, this happens in the very early stage when program starts. Because when I run ./lmp_auto without any input, same error still happens.
When I try make-serial mode, there isn't this kind of fault, so I believe that this problem is due to mpi conflict with LIGGGHTS. I have found some similar problem happened before, do you guys know how to solve this problem? Thanks a lot!
