Trouble compiling OGRE tutorial example.

I have built and installed Ogre to my Debian with Code::Blocks. Next, I tried to compile a tutorial application but I'm getting these errors:

obj/Debug/BaseApplication.o: In function `BaseApplication':
/home/ver/projects/testogre/BaseApplication.cpp:34: undefined reference to `Ogre::StringUtil::BLANK'

/home/ver/projects/testogre/BaseApplication.cpp:34: undefined reference to `Ogre::StringUtil::BLANK'
obj/Debug/BaseApplication.o: In funct开发者_JS百科ion `~BaseApplication':

I have added /usr/local/include/OGRE and /usr/local/lib/OGRE but that did not help. =(

when you compile you have to link OgreMain library to your executable.
