Re: Problem running X11 on PPC Mac
One of the people experiencing this sent me some sample code, and now I can reproduce it too, on both PPC and Intel. I would guess that there is an issue with the way shared library loading works in interactive mode, as opposed to in the link phase when compiling. You can work around the problem by launching ghci with DYLD_LIBRARY_PATH set to include the X11 shared library directory.

Christian P.S. I had to set DYLIB_LIBRARY_PATH, before it worked for me Actually, I've been able to build GHC from source using gcc 4.0.1 with no problems or special DYLIB_LIBRARY_PATH. I've also had no problems running X11 programs (from xterm) via either ghc or ghci. I'm not sure what's going on here. If you are still getting the unknown symbol you can fix it by adding -lSystemStubs to the link. That should happen automatically if everything is building properly. I think this may be a problem with the way the macports port is set up. Maybe try building it by hand, or using the binary distribution? (Although the Intel binary distribution is broken for X11, the PPC one works). Gregory, one thing to check: if X11 was installed properly, there should be a symbolic link /usr/lib/X11 - /usr/X11R6/lib/X11. If it's not there, then do: sudo ln -s /usr/lib/X11 /usr/X11R6/lib/X11 Also, are you running 10.3 (Panther) or 10.4 (Tiger)?

Brad, Did you apply the recent X11 update from Apple after you compiled ghc? If so, you might try uninstalling, cleaning and rebuilding the macports ghc. There is a path issue; you should not have to specify DYLIB_LIBRARY_PATH. At least in macports, this should be easy to fix.

Re: Problem running X11 on PPC Mac
This problem pops up sometimes for all sorts of open source software (try Googling _printf$LDBLStub), and can be due to mixing modules compiled by gcc 3.3 and gcc 4.0, and/or due to failure to link with - lSystemStubs. I've had good luck using X11 with GHC if I launch it first, and run GHC from inside Xterm rather than Terminal. That way you don't need to fiddle with DYLD_LIBRARY_PATH. I haven't tried it on PPC, though, just Intel. I'll try it at work tomorrow. You might want to do gcc_select and see which version of gcc is the default on your system, though is likely not the issue since you had problems with the binary distribution.
