CARLsim4 segfaults on Ubuntu 18.04

[Vladislav Sekulic]

Hello! I'm trying to use CARLsim4 on a modern Ubuntu 18.04 system with an NVIDIA GTX 1080. I have cloned the git repo and installed the nvidia 410 drivers as well as CUDA Toolkit 9.2. I initially tried using CUDA Toolkit 10 but there were too many problems building CARLsim4, so I reverted to 9.2.

Finally, I got CARLsim4 to build, but the hello_world example segfaults, as follows:

$ make

/usr/local/cuda-9.2/bin/nvcc -ccbin g++ -I/opt/CARL/include -L/opt/CARL/lib -Wno-deprecated-gpu-targets   src/main_hello_world.cpp -o hello_world -lcarlsim -lcurand

$ ./hello_world

The maximum axonal delay in the network (maxDelay) = 1

Segmentation fault (core dumped)

C++ is not my forte but if necessary I may try to attach a debugger and see if I can poke around a bit. 

Thanks in advance for any input!
