It sound like libgomp linkage doesn't work on your system. strange, it link
properly here.

I agree with comment #2 ,

/usr/lib/libraw_r.so.5: undefined reference to `GOMP_parallel_start'

Your libraw should not have undefined symbols.  libkdcraw can't fix that (well
shouldn't).

Well, libkdcraw could workaround it by adding extra linkage (to libgomp), but I
think that's the wrong approach.

pkg-config --libs liblcms2-dev
Package liblcms2-dev was not found in the pkg-config search path.
Perhaps you should add the directory containing `liblcms2-dev.pc'
to the PKG_CONFIG_PATH environment variable
No package 'liblcms2-dev' found

liblcms2-dev has been installed.

--- Comment #6 from Gilles Caulier <[hidden email]> ---
Perhaps there is a packaging problem with lcms2, but linking errors from libraw
come from libgomp, not lcms2. libgomp is OpenMP library used by GCC to
paralelize operation (with libraw, it's used to run in parallel some RAW
demosaicing tasks.

--- Comment #7 from Raymond Wooninck <[hidden email]> ---
Gilles,

Ben Cooksley asked me to validate this for openSUSE as that build.kde.org is
running openSUSE 12.3.  libkdcraw always worked fine as that it had an up-to-
date internal libraw tree.

Now with the removal of the internal libraw tree, libkdcraw falls back on the
libraw that is provided by the distribution. And this causes the above
indicated problem.

openSUSE 12.3 is using libraw 0.14.7 for libkdcraw for which the build fails
with the missing symbols.  if I compile libkdcraw against the latest openSUSE
Factory (using libraw 0.15.4) then libkdcraw is compiling fine without any
issues. I validated both libraw packages and the only difference is the libraw
version.

So I assume that libkdcraw needs libraw > 0.14.7

Regards

Raymond
openSUSE KDE community maintainer

I was thinking and it might not be directly libraw, but it could also be the
libgomp version that makes the difference.

For openSUSE this would mean the following combination:

l;ibraw 0.14.7 + libgomp 4.7.2 (snapshot 8 January 2013)
libraw 0.15.4 + libgomp 4.8.1 (snapshot 9 September 2013)

Raymond,

As i already said, here i use official libraw 0.14.7 from Mageia3, and all
compile/link fine. So i suspect that libraw version is not the problem, but
something in Suse packaging...

--- Comment #10 from Gilles Caulier <[hidden email]> ---
Ok, i understand the problem :

1/ under Mageia, libraw_r is not compiled with openmp support (i just check
with ldd)
2/ I compared libraw_r.pc between 0.14.7 and last version from gitm/master.
Look the difference in Libs definition :

master : Libs: -L${libdir} -lraw_r -lstdc++@PC_OPENMP@
0.14.7 : Libs: -L${libdir} -lraw -lstdc++

In 0.14.7, it miss OpenMP linker rules...

This is typically a bug in libraw, fixed in recent release.

As you said, the right solution for libkdcraw is to depend of libraw > 0.15.x

In all case, under Suse, you need to update official libraw version (Mageia
need this too)

Hello,

I've compiled and installed libraw 0.15.4 from sources :
http://www.libraw.org/download.

No more error in make digikam from
git://anongit.kde.org/digikam-software-compilation ( Revision 03a02db2)

I've build and compiled digikam from git://anongit.kde.org/digikam (Date de
compilation : Oct 23 2013 (cible : debugfull) Rév. :
fb30c5252509249d783307609a863d3a9c406564) whithout those error messages before
update of libraw. In digikam component, libraw 0.15.4 was mentionned but 0.14.4
(ubuntu precise package) was installed. Why ?

Thank you,

Eric

Do you uninstalled 014.4 before to install 0.15.4 ?

Do you recompiled/installed libkdcraw. By default libkdcraw is not recompiled
through digiKam SC. It's an option from cmake configuration:

Hello,

Yes, I have uninstalled libraw 0.14.4 (I think it was a kubuntu\backport
package) before to install 0.15.4.

But I don't take care of libkdcraw.

I will do it this afternoon.

Thank you,

Eric
