Trying to build cegui against Ogre, different basic types error

[m59gar]

Relative newbie here. Managed to get latest ogre SDK (prebuilt) and build cegui's dependencies and copy them over. Trying to build CEGUIOgreRenderer.

I get 50 errors all very similar to:

Error C2371 'Ogre::TexturePtr': redefinition; different basic types (compiling source file D:\CompileOgre\EditOgre\cegui-0.8.7\cegui\src\RendererModules\Ogre\Texture.cpp) CEGUIOgreRenderer-0


I've searched and found: viewtopic.php?f=10&t=6552&p=30585&hilit=TexturePtr#p30585

In that thread, he says 'I forgot to call hg update v1-9 on my Ogre sources' but I have no idea what that means. I have the latest ogre sdk and the latest cegui, so I don't think it's some sort of update problem. But I don't know enough to say for sure.

How can I fix this?
