Library won't compile.

This is the error I keep getting when I run "stack build" :

I've installed tensorflow 2.3.0 for the gpu at /usr/lib, with the headers at /usr/include. I'm using the latest version of Manjaro Linux, and stack version 2.7.5.

Hi. Did you give the --extra-include-dirs= and --extra-lib-dirs= part a try?

I've forgotten where cabal looks for libraries. In our CI, we are putting them in /usr/local/lib and /usr/local/include: https://github.com/tensorflow/haskell/blob/master/ci_build/Dockerfile#L40. If /usr/{lib,include} aren't included by default, you could try adding them at https://github.com/tensorflow/haskell/blob/master/stack.yaml#L23-L26.

[noahmartinwilliams]

Yes. I've also tried moving everything to /usr/local/lib and /usr/local/include, and that didn't work either. I remember that with cabal I used to need to pass it something like "--ghc-options=-dynamic" for arch-based distros, but I don't know how to do that with stack.
