Bug 863499

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.

Built for rawhide.

Build for f18 will be done once ghc-7.4.1 update gets pushed to stable.

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.
