Access violation when attaching a child window
Posted: Wed Aug 21, 2013 10:09
"Unhandled exception at 0x03253e52 in CEGUITest.exe: 0xC0000005: Access violation reading location 0x00000010." is the error message I get when I try to attach a child window to the root window. (the error doesn't actually appear on that line, see below)
I'm using CEGUI 0.8.2 along with Ogre 1.9 and Visual Studio 2010
Could it be that I failed to compile CEGUI correctly? I wouldn't be surprised, since I'm still new to C++ and all its compiling/linking mess
(And I don't find any tutorials on this site terribly useful either.)
CMake didn't find most of the dependencies (if any, not sure), but I changed my solution file and added the additional directories myself...
the error happens here: cegui/src/RenderModules/Ogre/RenderTarget.inl in line 134 when Ogre is rendering a frame
I set a breakpoint at that line I saw that it crashes the second time. I suppose the first time is the root window, while the second one is the child window (since the width/height in the debugger change)
Thank you very much in advance!
