Hello! I'm very exciting to use this project but I cannot run. Could you help me. I followed the installation steps,install three requirements. libfreenect: [https://github.com/OpenKinect/libfreenect] AntTweakBar: [http://anttweakbar.sourceforge.net/doc/] OpenSceneGraph: [https://github.com/openscenegraph/OpenSceneGraph]

when I make the project, encounter a problem.

 make
Linking CXX executable angkor
/usr/bin/ld: CMakeFiles/angkor.dir/main.cpp.o: undefined reference to symbol 'pthread_create@@GLIBC_2.1'
//lib/i386-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make[2]: *** [angkor] Error 1
make[1]: *** [CMakeFiles/angkor.dir/all] Error 2
make: *** [all] Error 2

Is this a problem about dynamic link library error? Or should I modify the CMakeList? What can I do to solve this problem? I really need this module to work and I will appreciate if you can help me. Thank !!

Change the last line of CMakeLists.txt to target_link_libraries(angkor freenect OpenThreads osg osgSim osgViewer AntTweakBar -lpthread) build again and see if that resolves the issue. We are adding -lpthread to the list of libraries.

Thanks for your reply! I add the -lpthread to the CMakeList, The previous error no longer appear ,Then another one arise.

Sorry, I cannot help you with that. See why libfreenect has that issue with your device. Maybe this helps.
