Duncan and Simon, thank you very much for dealing with this. After adding -v3 to the ghc-cabal invocation it reported gcc error on HsBase.h due to missing math.h file, i.e. system/library/math/header-math package was not installed yet. Thanks! Karel On 12/16/10 11:16 AM, Duncan Coutts wrote:
Do you have any idea what to install in order to proceed?
I don't know what's going on here, I'm afraid. Looks like Cabal tried to find HsBase.h and couldn't find it - so either it wasn't there (but you say it was), or Cabal was looking in the wrong place. Maybe follow up the latter hypothesis?
Cabal will report this error when it cannot compile HsBase.h, that usually means it is missing, but it's also possible that something just does not compile. This is like the check that ./configure scripts do. It's rather hard from the exit code of gcc to work out if it's genuinely missing, or fails to compile (though we could try doing cpp and cc phases separately).
One can run with -v3 to see the error that gcc reports.
