Apparently your cuda compiler nvcc is broken. What does running /usr/bin/nvcc --version give? What version of cuda do you have?

hi @pmh47, Thank you for your reply !
Cuda compilation tools, release 9.0, V9.0.176, /usr/bin/nvcc is a soft link (/usr/local/cuda/bin/nvcc) .

That's strange; your configuration of nvcc 9 + gcc 5.4 + cmake 3.10 should work correctly. I think there would have been more lines of output after Change Dir: /tmp/... in your original post, which should say what the actual error from nvcc was -- could you paste all of that output here?

maybe python 3.7 works? Can you tell me which version of python/anaconda/GL/ works ?
dependencies may conflict ! Thanks!

This is not a problem with dependencies (nor with DIRT itself); rather, your cuda toolkit installation is broken somehow. Googling the actual error nvcc fatal : Path to libdevice library not specified will give you some possible solutions.

Python 3.6 and 3.7 work fine, any conda that gives you tensorflow-gpu 1.6 or newer, and OpenGL from any nvidia driver newer than v367.

I'll close this issue as it's not a problem with DIRT.
