I am trying to bring a larger heap of code (http://141.57.11.163/auto/ ) into 6.4 land (because of wonder stories about faster compilation, faster execution, Data.Map, and so on ...) Here are a few observations and questions that may be useful to others as well. * what is the situation with ghc-6.4 for sparc/solaris? I don't see a binary package in the download area. I started to build from source - can this be successful? (The rest of this report refers to i386/linux) * Cabal is very nice! - The only thing that was confusing me is that I have to list all modules in the *.cabal file: if I don't, it still happily builds and installs the package but it cannot be used, giving linker errors. Couldn't this be checked earlier? Or better, couldn't it infer the needed hidden modules? Anyway I can generate the module list by a shell script but that does not feel right. - How do I build and install a profiling version of a package, how does Cabal support this? * (when building HSQL-1.4) CTime is no longer an instance of Integral, so I replaced fromIntegral by fromIntegral . fromEnum, is this OK? * the name of mkAppTy changed to mkTyConApp (I hope it's only the name that changed) * I don't see "dramatic" improvements in execution times - are there some magic ghc options I missed? I used -O -fvia-C. Still, executables are maybe 2 .. 5 % smaller and faster than they were with 6.2 - and compilation without -O is really fast. Best regards, and thanks to the GHC team. -- -- Johannes Waldmann -- Tel/Fax (0341) 3076 6479/80 -- ---- http://www.imn.htwk-leipzig.de/~waldmann/ -------
