Problem linking OS X Mountion Lion

[bilby91]

I have installed X11 and also this library without any problems.

When im trying to test my app i get this error

Loading package X11-1.6.0 ... can't load .so/.DLL for: Xext (dlopen(libXext.dylib, 9): image not found)

I have made a symlink to /usr because it installs X11 by default in /opt.

Hm. It's possible you don't have some of the extension libraries installed. Can you check what locate libXext says? If it doesn't return any hits, maybe you need to install some more (non-Haskell) things.

[bilby91]

The result of execution locate libXext is this:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11/lib/libXext.6.4.0.dylib
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11/lib/libXext.6.dylib
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11/lib/libXext.dylib
/opt/X11/lib/libXext.6.dylib
/opt/X11/lib/libXext.dylib
/opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/x11/xorg-libXext
/opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/x11/xorg-libXext/Portfile

i hope this helps.

Thanks!

Can you try running your program with this command line?

DYLD_LIBRARY_PATH=/opt/X11/lib:$DYLD_LIBRARY_PATH /path/to/haskellx11program

If that works, then perhaps you can figure out how to set up your linker correctly so that it knows about /opt/X11/lib.

I have set the DYLD_LIBRARY_PATH to the correct one, i don't get what i have to do with the location of my program.

Thanks

This fixed the problem "export DYLD_LIBRARY_PATH=/opt/X11/lib:$DYLD_LIBRARY_PATH" but after closing the terminal the issue persist. I suppose that this value that's set to the path variable remains only in that particular session. How can i set it permanently?

Thanks

If setting that environment variable fixes things, then you should man dyld to learn how to configure dyld properly. Setting DYLD_LIBRARY_PATH is just a workaround.

[bilby91]

Figure it out!

Thanks a lot for the help!

I'm a busy person, and these bindings have very low priority in my life right now. Moreover, I strongly suspect that the bug is in your code, not in the bindings.

Given these two facts, you have to give some pretty convincing evidence that the problem lies specifically in the haskell-pkg-janitors/X11 codebase (like "here's a patch that fixes the problem for me" or like "this minimal Haskell program has the problem and this straightforward C translation does not") before I plan on paying attention.

Good luck.
