I'm getting the following error when trying to compile hat using GHC 5.04 on a machine running RedHat Linux 7.3:
Hat cannot currently be built with ghc-5.04 at all, due to a bug in ghc which will be fixed in 5.04.1. However, that is not the cause of the particular error you report.
hmake -ghc +CTS -package lang -CTS -d /tmp/hat-2.00/targets/ix86-Linux/obj/compiler98 HatTrans

It looks like you originally installed your Haskell software in the following order: ghc-5.02.3, hmake-3.05, ghc-5.04. After installing ghc-5.04, you forgot to update the hmake configuration for ghc. To fix it, try hmake-config add ghc [ That updates your personal hmake configuration - to update the system-wide config, I suggest hmake-config /usr/local/hmake/ix86-Linux/hmakerc add ghc instead. (Obviously use the config file location for your machine.) ] You might also want to add the version-specific names for ghc, e.g. hmake-config add ghc-5.04 hmake-config add /usr/bin/ghc-5.04 Finally, you probably noticed that hmake was searching a whole bunch of package directories it did not need to - for package concurrent, posix, gtk, etc. This has been fixed in hmake-3.06.
