When trying to use the PRNG to generate some number ghc crashes:

λ gen <- newSkeinGen
λ take 5 $ randomRs (0,10) gen

Seems like yet another problem caused by the broken C compiler shipped with OSX. What happens if you remove all inline annotations in cbits and reinstall?

rnhmjoj commented 10 years ago

@valderman I removed inline in the functions of ubi.c. It compiled and now works just fine. Do you think it is an apple-gcc problem?

This exact error showed up again. This time with GHC 7.10.3 on NixOS.

ghc: symbol lookup error: undefined symbol: mk_config_tweak
