Installation problem about redner HOT 5 CLOSED

Solved issue, the env variable LD_LIBRARY_PATH was not properly set to the path for the embree library.
However, I am having a problem, I believe it is optix related:
Traceback (most recent call last): File "tutorials/01_optimize_single_triangle.py", line 6, in <module> import pyredner File "/home/hleon/anaconda3/envs/render/lib/python3.6/site-packages/pyredner/__init__.py", line 7, in <module> from .render_pytorch import * File "/home/hleon/anaconda3/envs/render/lib/python3.6/site-packages/pyredner/render_pytorch.py", line 4, in <module> import redner ImportError: /home/hleon/anaconda3/envs/render/lib/python3.6/site-packages/redner.so: undefined symbol: rtpContextGetLastErrorString
My cmake variables are as follows:

set(OptiX_INCLUDE "/home/hleon/NVIDIA-OptiX-SDK-5.1.1-linux64/include")
set(optix_LIBRARY "/home/hleon/NVIDIA-OptiX-SDK-5.1.1-linux64/lib64/liboptix.so")
set(optix_prime_LIBRARY "/home/hleon/NVIDIA-OptiX-SDK-5.1.1-linux64/lib64/liboptix.so")

Thank you for your help!

I think it's the same problem: is the lib64 directory of optix in your LD_LIBRARY_PATH?

from redner.

I does not work. It seems it is not importing correctly the headers. I tested Optix examples and they work. How did you install optix? I just did sh NVIDIA-OptiX-SDK-5.1.1-linux64-25109142.sh. What version do you have?
Thanks!

from redner.

I see the problem now. You linked to optix instead of optix prime. Try changing your optix_prime_LIBRARY variable to /home/hleon/NVIDIA-OptiX-SDK-5.1.1-linux64/lib64/liboptix_prime.so

from redner.

Great! Thank you! I did't even notice. Also I had to add /home/hleon/NVIDIA-OptiX-SDK-5.1.1-linux64/lib64 to the $LD_LIBRARY_PATH variable, and it worked.
Thank you for your quick answers and congratulations for your project.
