Description

when trying to install accelerate on Ubuntu building the llvm-native back end fails. It fails in different ways depending on the back end version

Expected behaviour

It should build successfully.

Current behaviour

It fails. See error below. [14 of 36] Compiling Data.Array.Accelerate.LLVM.Native.Distribution.Simple.Build ( src/Data/Array/Accelerate/LLVM/Native/Distribution/Simple/Build.hs, dist/build/Data/Array/Accelerate/LLVM/Native/Distribution/Simple/Build.o )

See the build log above for details.

Possible solution (optional)

Steps to reproduce (for bugs)

So this fails for Ubuntu and mx linux. I have ubuntu running in a vm (fresh install) so that it should be isolated. install cabal 3.2 (from hvr repository) install ghc 8.0.2 (apt-get ghc) install g++ (apt-get g++) install llvm-8 (apt-get llvm-8) run /opt/cabal/bin/cabal-3.2 install accelerate-llvm-native successfully build a lot of packages but fails on llvm-native backend with the error messages above.

Your environment

• Version used:
• Backend(s) used and version: cabal 3.2 accelerate-llvm-native 1.2.0.1 ghc 8.0.2 llvm-8
• Operating system and version: Ubuntu 64 bit 18.04.3 (both running from inside virtualbox and native although currently just in virtualbox)
• Link to your project: Don't have one yet because I cant install this.
• If this is a bug with the GPU backend, include the output of nvidia-device-query: This is a cpu bug. Note that when I was running nativly I once managed to get the ptx backend to install but got the same error messsage from above.

I think the (old now) 1.2 release of accelerate-llvm-native isn't going to work with Cabal-3.x. The current GitHub version should avoid this problem though, can you try installing that? I plan to make a new release as soon as possible...

(Also, sorry for the very late reply! I've been swamped and only just saw this)

At some point I'll cut a new package release, but at least this is fixed on master now, so closing. Thanks for your patience!
