System.AccessViolationException buidling with OGRE
Posted: Tue Jan 31, 2012 23:05
Hi,
I am making a game, and it uses OGRE and is successfully compiled with it.
My VS2010 solution contains two projects, Game and Gui, where Game is a console application and Gui is a static linked library, and Game references Gui.
G:\Game\Code\MyGame is the solution directory.
The Gui project has a class called HUD which I create an instance of, i then call a void method called init() to initialise all the CEGUI stuff and then i create an instance of Game and start the game.. etc.
Looks pretty much like this:
I have built all the CEGUI stuff successfully (its version 0.7.6) and added the lib directory to Gui, and the lib files required:
CEGUIBase_d.lib
CEGUIOgreRenderer_d.lib
I have also made sure to add the bin directory for the dlls for CEGUI to the Game project so it can see them when it runs.
This is the code that is currently in the void init() method in the HUD class.
I added a little bit of code at the top so I could see the current working directory in the console just incase.
All the cegui datafiles are in "F:\Game\Code\MyGame\media\cegui"
Now when I run the application, it runs fine, ogre all gets initialised correctly until it gets to this line :
Then I get a System.AccessViolationException :
Can anyone shed any light on this?
Any help would be very very appreciated.
