• First, I did run this make clean... command in the first line and i received errors from line "There is some error when .... ".

• After i run just command "xrun -64bit...." that i received a new error in the image below.
  

I already boiled the error in the image. The correct path is home/usr21/ibex/dv/uvm/core_ibex/sigusrdump.out.

Please check this error as soon as possible and notice me in this bug issue.
Thank you!

I'm not sure exactly what's going wrong, but the symptom is a segfault in the simulation binary (which presumably happens after some memory corruption that's trashing the string holding the path that gets reported afterwards).

To debug it further, you'll need to add some debug prints to figure out what code is running. I suspect it will be some C++ function that we're running over DPI. Then add some prints to that code (to stderr so it doesn't get buffered) to figure out exactly what is exploding.
