Cannot compile libkface

[Gabriel Voicu]

Hi everyone,

I'm trying to compile digiKam 2.0 after a while, but I'm stuck at compiling libkface. I have all the required dependencies, including OpenCV 2.1 . Can you tell me please if this is from me, or is something broken in the compile?

Btw, sorry for coding so rare in this period, I am pretty busy at the university. Even if, I promise that my work will be finished until the first beta release.

I'd say that when linking, all methods from the OpenCV library are not found.
That means the headers are found by the compiler, but the corresponding
libraries not by the linker.
Either, there is an installation peculiarity at your side, or some problem
with the CMake detection.

Here on OpenSuse, the package opencv-devel provides, in addition to the
headers:
/usr/lib64/libcv.so
/usr/lib64/libcvaux.so
/usr/lib64/libcxcore.so
/usr/lib64/libhighgui.so
/usr/lib64/libml.so

Ok ;-)

/usr/lib64/libhighgui.so
/usr/lib64/libml.so

I checked now and I have all these OpenCV libs in my /usr/lib directory.
I suppose that is a cmake error, because if I download and compile libface from sourceforge,
all works as it should. Also, after I compile libface from Sourceforge, running cmake from libkface
doesn't detect that I already have installed libface.
(I mention that I used:
"cmake -DCMAKE_BUILD_TYPE=debugfull -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` .."
command when compiling all the digikam's components. Also, I use Fedora with KDE 4.4.2 .)

I think I just encountered the same problem, see the commit which I
CC'ed to the list. Does it work for you now? Marcel, does the commit
break the build for you?
