[Libface-general] compilation of the examples failed

[Tobias B. <Tob...@we...>]

Hi,
I am interested in your work and tried to compile your code on my machine.
Unfortunately, the examples do not compile. This is what I did:

1) installed the OpenCV-2.1.0
2) svn co URL: https://libface.svn.sourceforge.net/svnroot/libface (Revision
232)
3) cd libface;
    mkdir build; cd build;
    cmake -DCMAKE_INSTALL_PREFIX=/usr .. -DBUILD_EXAMPLES=1
-DBUILD_DOCUMENTATION=1 -DCMAKE_BUILD_TYPE=Debug
4) make; sudo make install

To my understanding, the examples should have been build, since I did an
-DBUILD_EXAMPLES=1 in my cmake configuration. But, they are not.


However, manually compiling the examples, by

g++ -I /usr/local/include/libface -o FaceDetectionExample FaceDetection.cpp
-L /usr/local/lib -lface -lhighgui -lcv -lcxcore -lcvaux

works. Note, that I had to extend the include path by libface.


Another question. Is the config file libface-config.xml missing in the
repository? The 'Train' and the 'Test' example both exit with an
segmentation fault. (see below)

Thanks in advance, Tobias
