Hi,

I tried to compile and run the ohello (https://github.com/uic-evl/omegalib-history/tree/master/examples/ohello).

When I run ".\ohello", it says " [SystemManager::setupDisplaySystem] could not find library libdisplaySystem_Equalizer.so", but libdisplaySystem_Equalizer.so is in $OMEGA_HOME/master/build/bin folder.

Any suggestion please? Also can I ask if there are other OpenGL examples please?

Thanks a in advance!

Just to clarify my problem.
Orun works well, but both ohello and cyhello2 "couldn't find libdisplaySystem_Equalizer.so" or libdisplaySystem_GLFW.

Thanks!

I moved the cyhello2 to the directory master\build\bin, and it works now! :-)
But nothing is displayed in the window for ohello (actually I got just one black window). Any help and suggestion please? Is there anything I did wrong about that?

Thanks.

Sorry I posted so many questions.

Now I can make ohello runs successfully locally. But I have problems when the config file is for two nodes.
It says "./ohello: error while loading shared libraries: libomega.so: cannot open shared object file: No such file or directory", but when there is no other node in the configuration file I didn't have the error.

Thanks.

Please ignore my stupid question.

I added "LD_LIBRARY_PATH=%d" before "%c -r" in nodeLauncher in the configuration file, and also added the same thing before "./ohello". It works now.

Thanks,
Henan

I'm glad you were able to get this fixed. No worries about the questions, It is good to have this information on the forum as it might be very useful for other people :)
