What steps will reproduce the problem?
1. svn checkout http://ehci.googlecode.com/svn/trunk/ ehci-read-only
2. edit CMakeCache.txt to enable //Build OpenGL Samples 
BUILD_OPENGL_EXAMPLES:BOOL=ON
3. cmake .

What is the expected output? What do you see instead?
diediaga@diediaga-laptop:~/ehci-read-only$ cmake .

Please, try installing the libxmu-dev package, probably like 'sudo apt-get 
install libxmu-dev', through synaptic or something similar.
And if you have some time, please, write back the results.

Best regards,
Daniel

hi. Thanks for your fast reply
I install that lib without problem now cmake works well. 
but I got some another problems with make :(

when I type make
I got this error
[ 28%] Building CXX object samples/CMakeFiles/6dofhand.dir/6dofhand.cpp.o
/home/diediaga/ehci-read-only/samples/6dofhand.cpp:9:58: error: glut.h: No 
existe el archivo o directorio

So I open the file 6dofhand.cpp and change the lines 
#include <glut.h>    // Header File For The GLUT Library 
to this one
#include <GL/glut.h>    // Header File For The GLUT Library 

now it founds the glut library.

but again another error compiling this example:
[ 14%] Built target Ehci
[ 28%] Building CXX object samples/CMakeFiles/6dofhand.dir/6dofhand.cpp.o

Hi Diego, thanks for trying it out and rewriting the correct position of Glut.
Now, your problem is about finding the glut library for linking.
I cannot tell you why CMake hasn't found it. Firstly, I'd try to clean all your 
cache and run the configuration process again. If it does not work, I'd tell 
you to dive down into the CMake files and finding out what is the place it has 
found glut library.
This thread seems to be related to what you should do

Just change the cd into OpenSceneGraph to EHCI directory and try to find what 
CMake has put in you OPENGL_glu_LIBRARY entry. The full link to this thread is

hi Robert
I installed ccmake and also cmake-gui and check that the libs are there
I can see that all the libs are found in my system.
except 
OPENGL_xmesa_INCLUDE_DIR         OPENGL_xmesa_INCLUDE_DIR-NOTFOUND 
do you think this could be the problem?
I google about this but I can't fine any solution about.
I can compile and run version 0.6 with not 0.7 or svn
I will continue looking for a solution this weekend
kind regards

Hi Diego,

try and force the -lGLU linker flag in the compile command line...
maybe you can manually change it in the makefile... and then we discover what 
is avoiding cmake from getting the glut flag...

Hi,
If you add "${OPENGL_gl_LIBRARY} ${OPENGL_glu_LIBRARY}" to the CMakeLists.txt 
file in the samples directory on lines 56,58,60,62 like this:

TARGET_LINK_LIBRARIES(zoomHand ${OpenCV_LIBS} ${OpenGL_LIBS} 
${OPENGL_gl_LIBRARY} ${OPENGL_glu_LIBRARY} ${GLUT_LIBRARY})

it compiles with the samples without any problems. The two libraries need to be 
added for each file that needs to link with them. For some reason 
${OpenGL_LIBS} does not get put together correctly.

Also, glut.h is not being found because the GLUT_INCLUDE_DIR is not getting set 
correctly. I ran "ccmake ." and pressed 't' to get to the advanced options. 
Then I changed the GLUT_INCLUDE_DIR from "/usr/include" to "/usr/include/GL". 
The header file is found without changing each cpp file that uses glut.h

Regards,
Sam

That's a very good job. It seems you've dug into Cmake :)
Awesome, 
I'll mark the issue as closed, thank you a lot!
