I have been trying to get a robotics simulator (gazebo) to compile under OSX. After a lot of struggle I finally got everything to compile and run, however I could not get focus on the gazebo window and it seemed no mouse events were recorded. After googling this could apparently be fixed by adding :
Code: Select all
set_property(TARGET gzclient PROPERTY MACOSX_BUNDLE TRUE)to the CMakeLists.txt. However after adding this, I get another segmentation fault, in CEGui this time. I get the same error if I remove that line from the CMakeLists.txt again and rebuild, so I am not sure what is causing it. The backtrace is :

Furthermore it seems in mac_loadExeBundle that it failed to find the bundle (I don't know where the log is, but logger->logEvent("-- Couldn't get bundle from main app bundle reference; trying CEGUIbase instead."); is getting called). The 'name' parameter in this case, according to gdb, is :
Code: Select all
(gdb) p name
$1 = 0x1053a1ec0 "\020\016Dx?"That doesn't seem right? Is there something gone corrupt? Is there any additional information I can provide?
EDIT: I added "net.sourceforge.crayzedsgui.CEGUIBase" to the Info.plist for CFBundleIdentifier, not sure if this is intended but it did solve (this) segmentation fault, on to the next xD (Failed to load module 'CEGUIExpatParser': Unknown Error)
