Description of problem: In f18 current (alpha), leksah fails to start with the following error on the command line: leksah: error while loading shared libraries: libHSleksah-0.12.1.3-ghc7.4.1.so: cannot open shared object file: No such file or directory Indeed, ldd /usr/bin/leksah reports: linux-vdso.so.1 => (0x00007fffdd7ff000) libHSleksah-0.12.1.3-ghc7.4.1.so => not found libHSutf8-string-0.3.7-ghc7.4.1.so => /usr/lib64/ghc-7.4.1/utf8-string-0.3.7/libHSutf8-string-0.3.7-ghc7.4.1.so (0x00007f69b6102000) libHSregex-tdfa-1.1.8-ghc7.4.1.so => /usr/lib64/ghc-7.4.1/regex-tdfa-1.1.8/libHSregex-tdfa-1.1.8-ghc7.4.1.so (0x00007f69b57d5000) libHSregex-base-0.93.2-ghc7.4.1.so => /usr/lib64/ghc-7.4.1/regex-base-0.93.2/libHSregex-base-0.93.2-ghc7.4.1.so (0x00007f69b55b1000) libHSleksah-server-0.12.1.2-ghc7.4.1.so => /usr/lib64/ghc-7.4.1/leksah-server-0.12.1.2/libHSleksah-server-0.12.1.2-ghc7.4.1.so (0x00007f69b51e3000) [ ...SNIP... ] It seems the other SOs are found correctly. libHSleksah-0.12.1.3-ghc7.4.1.so is installed in /usr/lib64/ghc-7.4.1/leksah-0.12.1.3/ Version-Release number of selected component (if applicable): ghc-leksah-0.12.1.3-5.fc18.x86_64 leksah-server-0.12.1.2-5.fc18.x86_64 ghc-leksah-server-0.12.1.2-5.fc18.x86_64 leksah-0.12.1.3-5.fc18.x86_64
I will take a look. Setting LD_LIBRARY_PATH to the leksah directory inside /usr/lib64/ghc-7.4.1 works. I will check why the path information is not getting written while building the rpm.
The rpath information in leksah starts with /builddir/build/BUILD/leksah-0.12.1.3/dist/build and hence the "library not found" error. leksah exports modules in a library package and this package is in turn listed as a dependency for the executable. If we use --shared option, this exported package becomes a shared library dependency for leksah binary. Before 7.4.1, I patched leksah to remove the library as a dependency. This was done to solve an issue that occurred while running haddock after build ( http://hackage.haskell.org/trac/hackage/ticket/656 ). The issue got fixed in 7.4.1 and I removed the patch. This "library not found" issue could have been there before but never surfaced because of the patch. I checked that putting the patch back again removes libHSleksah-0.12.1.3-ghc7.4.1.so as a dependency of leksah binary and the issue is fixed.

I see - sorry my fault for just dropping that patch earlier. The self-dependency is "interesting" though - maybe worth asking upstream about the story behind it? As such it has the potential to save a lot of build time. How about trying to use chrpath to edit the RPATH in the leksak binary instead?
So actually I had the same problem when moving "back" to monolithic haskell-platform. Anyway I think you can fix it like this: BuildRequires: chrpath : : %install : PROG=%{buildroot}%{_bindir}/%name RPATH=$(chrpath $PROG| sed -e "s!^$PROG: RPATH=!!") case $RPATH in *$PWD*) NEWRPATH=$(echo $RPATH | sed -e "s!$PWD!%{ghclibdir}!g" -e "s!/dist/build!!g") chrpath -r $NEWRPATH $PROG ;; esac (taken from haskell-platform.spec though untested here). Then you could drop the patch and benefit from the shared lib. In the long term I would like to see all dynamically linked binlib haskell packages doing this.
Jens, I think you were right in dropping the patch earlier because the haddock issue was fixed in ghc-7.4.1. Thanks for the new patch. I did modify rpath of leksah binary using chrpath and was able to get it working. I will incorporate this into the spec file for f18 and rawhide.
Jens, I have built leksah for F18 with the deps patch. I will try out the patch that you have mentioned in comment 6 in rawhide and then port it back to F18. Will keep this bug open.
