Problems building OgreBullet Demo

Hi!
I tried to build the OgreBullet demo, just to test my OgreBullet dlls
but I get some Errors, some relating to my OgreBullet dlls and cpps, and also to my MinGW installation as well...

Can maybe someone help me?
I am using the latest OgreBullet Version from the CVS and Ogre 1.4.9 with MinGW for Code::Blocks...

The most of the time there are undifind references... but i can't figured it out why...
