Structure of nvidia-cuda-toolkit seems to have changed in Ubuntu 18.04 about cuda

Thanks for the heads up! I also haven't tried the package from apt in a long while because it always lagged so far behind. I guess I should try and make it work with that again.

I think that it is just the apt package which changes the directory structure... my cuda-9.1 install using the regular nvidia installer has the usual folder structure in /usr/local/cuda. We'll probably need a separate change to make accelerate-llvm-ptx understand the folder structure used by apt as well.

It is still looking for the nvvm directory because that is where the standard math library is located, which contains the implementations of sin(), cos(), etc.

Hey np!

So the initial structure of /usr/lib/cuda is:

/usr/lib/cuda$ ls
bin  include  lib64  nvvm  version.txt

bin, include, lib64 are all empty, nvvm contains libdevice
I set CUDA_PATH to be /usr/lib/cuda

I symlinked include as /usr/include and cuda built (because of missing cuda.h)

My simple executable compiled with accelerate-llvm-ptx, but wouldn't run because of missing ptxas at bin/ptxas so i symlinked bin as /usr/bin and everything ran.

Wasn't too bad

I think this is fixed and can be closed with AccelerateHS/accelerate#444
