libface CMake change

Hi,
I've made a change in libface's CMakeLists.txt. It now installs libraries not in <PATH>/lib64 but in <PATH>lib. I had to do this because on my new fresh system (Arch), examples wouldn't link. I also suspect that most libraries go into lib instead of lib64, even on 64-bit systems.
So if anyone has a problem, let me know and I'll undo the changes. Do remove the (old) .so files from lib64 if you have installed them as root. Thanks

I will test this on the week end.
Q : Do you have compiled libface + libkface under windows ? which compiler you use ? Which version of OpenCV you use ? Do you have compiled OpenCV ? Here, i use MinGW with GCC 3.x. OPenCV do not compile fine. Installing Gcc 4.x is very complex. I don't find a simple and functional way for that. Any tips are welcome.

This might be helpful : http://tdm-gcc.tdragon.net/ It is a build of the latest GCC 4.5 for windows. I didn't compile OpenCV, I just got the latest installer and installed it. It won't compile with 3.x On Sat, Jun 26, 2010 at 3:34 PM, Gilles Caulier <[hidden email]> wrote: I will test this on the week end. -- Aditya Bhatt Blog : http://adityabhatt.wordpress.com Bitbucket: http://bitbucket.org/aditya_bhatt Face Recognition Library : http://libface.sourceforge.net _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

And you link with GCC4 and OpenCV bin package ? This one is compiled with M$ Visual C++. Binaries are not runtime compatible Do you use M$ compiler (nmake) ?

Hi,
I just tried compiling libface and libkface. Here are some comments: - The libface website states 'you need FindOpenCV.cmake'. Where do you get it? I just used the one from kipi-plugins, but that one must be the wrong one, as it defines OpenCV_LIBRARIES and libface looks for OpenCV_LIBS. The same applies to libkface. Would it be possible to include FindOpenCV.cmake in lib(k)face, as is done in kipi-plugins? - I ran libfaceGUI from libkface. When I load an image and hit "Detect faces", nothing happens but on the console I get: Chosen area : 500000 Minimum FaceSize is 35 ERROR: Could not load classifier cascade. Minimum FaceSize is 35 ERROR: Could not load classifier cascade. Total Time taken : 0.000000 secs. Making long vector took: 0.000000 sec. Faces parsed : 0, number of final faces : 0 Prunning took: 0.000000 sec. ERROR: Could not load classifier cascade. libkface detected : 0 - libface only recognises CMAKE_BUILD_TYPE=Debug, but not debugfull which is also listed here: http://techbase.kde.org/Development/CMake/Addons_for_KDE Would be nice if both were detected, then I don't have to add special flags in kdesvn-build for libface.

One more thing: I think that on the first try to compile libkface tests,
compilation failed because it could not find libkface include files because they were not yet installed. Running make install/fast and then re-running make solved that problem.

Under Mandriva 2010.1, all compile fine there... but with Mandriva 2010.0, no... I suspect an update of CMake between both version which handle properly this file during search of OpenCV Gilles _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

Hi Michael,
OpenCV 2.1 (which has been out since several months now, I think) comes with FindOpenCV.cmake. What Alex wrote on the website refers to that.
Gilles reported the same problem to me a few days back. It looks like you're using Mandriva. Mandriva (unlike most other distros) ships OpenCV split into multiple packages. You probably need to install a package named something like "opencv-samples".
Ok. I'll try to fix it. But I'm not very knowledgeable about CMake configuring, can you tell me what to do?

A yes. Something must be backported form libkexiv2 to handle local dir
to compile fine in time : http://lxr.kde.org/source/KDE/kdegraphics/libs/libkexiv2/test/CMakeLists.txt#1 Gilles 2010/6/26 Michael G.

The problem was again the wrong FindOpenCV.cmake, as #define OPENCVDIR "@OpenCV_DIR@" in LibFaceConfig.h was then defined as an empty string ;-) So I manually set it to /usr/share/opencv, now detection and also recognition work as they should ;-) Very nice indeed! Thanks for the hint! Now all that is needed is a way to remove 'false faces' where there is no face, it looks like they are added to the database even if I do not give them a name.

Now all that is needed is a way to remove 'false faces' where there is Good to hear that it works now. About the false faces, the recognition/training mechanism is almost done, but not yet complete. I'll hopefully make it better in the next few commits. Wrestling with a few bugs. I'm going to add a "cross" button like iPhoto has, to reject false faces, I'll do it after I fix those bugs. Wait a while :)

Hi,
I'm not entirely sure, is there any new "standard" which says that there's no need for a separate lib64? For example, in my Arch system, I'll have to tweak stuff with the linker to make it see .so's inside lib64. It *looks* like they've deprecated lib64.

For me, if i had a lib64, it was always a symlink to lib.

I never had a lib64 (I'm using Arch 64-bit). It's not in the "linker path" (whatever it's called).

Ok, I checked my dad's kubuntu system, /lib64 and /usr/lib64 are symlinks to /lib and /usr/lib respectively.

Fedora 13 64bit (but previous too) does not use symlinks from /usr/lib64/ to /usr/lib/. The 64bit libs goes only to lib64/, while 32bit libs are in lib/. I'd like to keep it that way too. Isn't there some kind of system variable to know where to put lib files?
