And, when GHC is successfully built with dynamic library support (with tweaks), it doesn't build or link dynamic libraries properly. I've provided a set of patches, broken up with explanations. We need to discuss whether adding an -install-name option to GHC is acceptable to the GHC team. Note: A separate patch for Cabal uses the new -install-name option. Without this applying this in the ghc tree, the Cabal installed along with ghc will not generate shared libraries on Mac OS/X with the right install name. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/3550 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

Another thing - this line in the patch... -install-name $(ghclibdir)/`basename $$@ | sed 's/^libHS//;s/[-]ghc.*//'`/`basename $$@` ...is a bit brittle because it second-guesses the behaviour of other makefiles, so some re-factoring is probably desirable here (assuming you decide to go with this approach). --- Some other Mac OS/X issues: 1. The general wisdom of using absolute paths on Mac OS/X: My take on it is that GHC does things the Unix way where it installs into an absolute location. If you want to package your application up Mac OS/X style (where the whole directory is required to be moveable), then the developer needs to make a process for doing that anyway. Perhaps at that point, they would just add the extra step of modifying all the shipped libraries to use relative paths (this can be done using a Mac OS/X system utility). 2. You can't run an app (one that has a library and an executable in it) from the build tree because it wants to use the install location. I don't know the solution to this, but it's only a minor annoyance mostly, and it seems to me that it could be dealt with later as a separate issue. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/3550#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
