Unresolved external symbol when compiling with static libs
Posted: Mon Apr 19, 2010 17:50
Hello there,
I got those linker errors:
when compiling my application with CEGUI static libs (I added these libs in the additional library dependencies):
I can get rid of the errors if I use the DLL version of CEGUIBase and CEGUIOpenGLRenderer:
- CEGUIBase_Static.lib to CEGUIBase.lib
- CEGUIOpenGLRenderer_Static.lib to CEGUIOpenGLRenderer.lib
But I want to minimize the use of DLLs in my application.
I just started using CEGUI by reading the docs and tutorial, and only used 2 objects from CEGUI: CEGUI::System and CEGUI::OpenGLRenderer.
Probably that's why I can get rid of the errors only by switching to DLL version of the 2 libs (Base and OpenGLRenderer), but I'm sure that I will have to use the DLL version of the other libs when I start using them (such as SILLY, ExpatParser, and Falagard)
Please kindly guide me out of this error =) I am new to CEGUI.
Additional information:
- I am using Multi-threaded DLL (/MD) runtime
- The application I am creating is using wxWidgets 2.8.10 in an SFML 1.6 (OpenGL) canvas, both static library.
- Microsoft Visual C++ 2008 Express
Any kind of help would be appreciated
