Yes, the tree was broken for some time between yesterday and today, and you appear to have gotten unlikely. It should have been fixed now, so you should try again. Cheers, Edward Excerpts from Scott Lawrence's message of Sat Jun 11 12:44:18 -0400 2011:
Trying to compile GHC7 from source (as the ubuntu repository is still on GHC6), I came across the following error in the final phase:
libraries/base/GHC/ST.lhs:78:1: You cannot SPECIALISE `forever' because its definition has no INLINE/INLINABLE pragma (or its defining module `Control.Monad' was compiled without -O)
This was after:
git clone [...] ./sync-all get perl boot ./configure make
Is there some problem with trying to build GHC7 on a machine with GHC6, or did I just get the build procedure wrong (the last line of the error looks like a hint that I did).
