in GNU/linux fedora 12
at “cmake .”

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
GLUT_Xi_LIBRARY (ADVANCED)
linked by target “configapp” in directory /home/marz/multitouch/src
linked by target “smoke” in directory /home/marz/multitouch/demos/smoke

– Configuring incomplete, errors occurred!

I fix it installing the libXi-devel.i686
Awesome work

in GNU/linux ubuntu 9.04
at “make install” i get this error (don’t pay attention to the spanish things):

g++ -shared -Wl,-soname,liboscpack.so -o liboscpack.so.1.0.2 ./ip/IpEndpointName.o ./ip/posix/NetworkingUtils.o ./ip/posix/UdpSocket.o ./osc/OscOutboundPacketStream.o ./osc/OscPrintReceivedElements.o ./osc/OscReceivedElements.o ./osc/OscTypes.o -lc -fPIC
/usr/bin/ld: ./ip/IpEndpointName.o: relocation R_X86_64_32 against `a local symbol’ can not be used when making a shared object; recompile with -fPIC
./ip/IpEndpointName.o: could not read symbols: Bad value
collect2: ld devolviÃ³ el estado de salida 1
make: *** [liboscpack.so.1.0.2] Error 1

i fix it editing the makefile like this
change this line
COPTS = -Wall -O3
for this one
COPTS = -Wall -O3 -fPIC

i hope help someone
thanks for this great tutorial!

Hello! very valuable info , but unfortunately I can’t get any signal from my camera to any of the demo applications (they compile fine).

I use Fedora 10. At /dev there’s nothing like cam0 or similar that is requested at the CvCaptureFilter.cpp . I ‘ve been experimenting with fw0 etc which do appear at the /dev folder. Any ideas?
Thanks in advance!
