Error while running ./RayTracer --scene 6 --height 320 --width 448 #7

The build of mesa and vulkan-sim is successful. While running the Raytracer, I am getting symbol lookup error: '~/vulkan-sim-root/mesa-vulkan-sim/lib/lib/x86_64-linux-gnu/libvulkan_intel.so: undefined symbol: gpgpusim_setGeometries'. Please have a look at it. My environment is CUDA11.1, gcc9.4, boost1.71 and embree-3.13.4. 图片

Hi,

Could you modify a few lines in this file? https://github.com/ubc-aamodt-group/mesa-vulkan-sim/blob/main/src/intel/vulkan/meson.build

  1. Comment out lines 30 and 31.
  2. Uncomment lines 29, 32, and 33, then modify the path in line 29 to be the libcudart.so of the vulkan-sim or gpgpusim library path.
  3. You probably should also modify the embree_lib_dir and embree_header_dir paths in lines 22 and 23 of the file as well.
  4. Recompile both mesa and vulkan-sim.
  5. Try running the workload again.

Please let me know if the fix works!

Thank you very much! The fix works! I noticed that my mistake was to change the path on line 29 to libcudart.so in cuda11.1........
