[lammps-users] A compiling problem

Hi,all

I write a new pair_style “pair_style sh/cut” and I make it successfully.
When I run a simulation using it in it, "Segmentation fault " appears.
So, I debug it with “gdb” and the informations given are:

gdb) where
#0 0x00000000005bc025 in LAMMPS_NS::PairSHCut::compute (this=0x9a4e200, eflag=1, vflag=)at pair_sh_cut.cpp:153
#1 0x0000000000590f88 in LAMMPS_NS::PairHybrid::compute (this=0x9a4dd70, eflag=1, vflag=) at pair_hybrid.cpp:93

#6 0x000000000051f797 in main (argc=1, argv=0x7fff56659118) at main.cpp:29

Is there anyone who can give me some help ? Any help will be appreciated!

Best wishes

In addition, my system is redhat and the compiler is mpicxx.

well, gdb tells you that it crashes in your code and on line 153 at that.

since i am not a psychic, i don't know what you have written there,
so it is up to you to debug your own errors.
