Hello list. Up to now I've only used binary versions of GHC, but since my operating system's (OpenBSD) version of GHC is lagging behind (currently at 6.6.1), I need to update it. I tried using my system's ghc-6.6.1 to compile ghc-6.10.4 but it failed due to haskeline not being installed (and trying to install it also failed). I managed (woohoo!) to compile 6.8.3 using 6.6.1, but I could still not use 6.8.3 to compile 6.10.4. Even though I have installed haskeline using cabal in 6.8.3, the making of 6.10.4 breaks with the (weird?) message: cabal-bin: At least the following dependencies are missing: haskeline -any On the same machine (it's a laptop), I also have a partition with ubuntu linux installed (which has ghc-6.10.4 installed). So I thought I should try cross compiling, following the instrucions at the Porting wiki page. But this also failed at the first steps, with the complaint: GHC configuration does not support differing host/target (i.e. cross-compiling). Any suggestions / website links? Also, I understand what --host and --target are supposed to be, but I'm not clear on --build. Is there a more detailed document on building GHC, other than the Porting wiki? Thanks. P.S. I don't really use the ubuntu linux partition, so if there is an easier alternative that needs to install another system, I can do it over ubuntu's partition. -- Thanos Tsouanas http://mpla.math.uoa.gr/~thanos/
