[Help] Linux compilation error

While compiling PLSM2 I recieved the following error:

make[4]: *** [OgrePagingLandScapeOctreeAxisAlignedBoxSceneQuery.lo] Error 1

I get this error with the latest (07/13/06) CVS and with the zip from the website (1.2). I am using gcc 4.1.1 and OGRE 1.2.1.

I found my error. Apparently I compiled OGRE with gcc 3.2 and forgot that I upgraded to gcc 4.1.1. I simply recompiled OGRE and everything works.
