Bugzilla Bug 144382

media-gfx/digikam-0.9.0_beta1 fails to emerge with -Wl,--as-needed in LDFLAGS.
Previous versions of digikam emerge fine with it. Removing --as-needed from
LDFLAGS fixes this.

Reopen with some errors and emerge --info.

log of the failed emerge

...Wrong time of the day, forgot the emerge --info, log follows...
Jakub: You are simply too fast to let any errors slip ;)

This happens because media-gfx/digikam from version 0.9.0 and on depends on
media-gfx/exiv2 instead of media-libs/libexif.

Patch to fix build with --as-needed

I've attached a simple patch for the problem. It's doing nothing more then
reordering the order of libs in the digikam/showfoto/Makefile.am to put the
external libs behind the internal ones.

Created an attachment (id=98468) [edit]
Updated ebuild to use the proposed patch

A new ebuild with the patch included, version number is unchanged since it
changes nothing for those without --as-needed and simply allows a compile for
those with it. ;-)

I did also submit the patch upstream for inclusion into the next version
hopefully. See: http://bugs.kde.org/show_bug.cgi?id=134924

Thank you. We'll add it ASAP.

The patch got submitted upstream (see comment #8 for link), seems to be a
correct fix. ;-)

Thanks David, I've had to oversee this up to now, but will merge it today.

Pinging the right people yields a shockingly fast result it seems. ;-)

Indeed, especially because I filter --as-needed bugs as low priority usually ;)

Should probably try to find a way to differentiate bugs waiting for patches and
bugs with a patch already present.

Forgot to close the bug, committed now :)
