cabal reports “/usr/bin/ld: cannot find -lHSrandom-1.0.1.1-ghc7.8.3”

Question

I have Ubuntu 14.04LTS. I downloaded the latest ghc-7.8.3 from http://www.haskell.org/ghc/download_ghc_7_8_3#x86_64linux and installed it to /usr/local

Answer 1

I remember having a similar issue when setting up ghc-7.8. It has something to do with the new cabal, which somehow isn't compatible with libraries installed with an older versio (but it fails to give the correct problem reason.

Anyway, I think reinstalling the packages in question

cabal install random --reinstall --force-reinstalls 

sets it up so cabal install tf-random should then succeed.
