That's right. I do install the CUDA SDK on Travis, so I end up with a CUDA installation with a working nvcc that the cuda Haskell package can use, but I don't install any drivers, so I don't think I'd be able to actually run any CUDA code (since nVIDIA seem to have removed the emulator that used to be in the SDK -- from a quick search, it seems that Ocelot is the only emulator for Linux now).
Here's what I do in the regression suite: wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1204/x86_64/cuda-repo-ubuntu1204_5.5-0_amd64.deb sudo dpkg -i cuda-repo-ubuntu1204_5.5-0_amd64.deb sudo apt-get update sudo apt-get install cuda-5.5 That seems to be enough to convince the config scripts for the cuda package that there's a real CUDA installation there, and it's enough to build the package. When I have time, I'll play with getting Ocelot working. Then we'll be able to run the package tests for all of these things as well.
