Link problems


Hi,

I am developping application called MathPlanner. It is created with gcc 2.96 
and is working ok. Same days ago I installed gcc 3.0.4 from my linux 
distribution disk. MathPlanner compiles with no errors or warnings. But it is 
unable to link.   It does not find symbols from shared library libqt-mt.

lot of these  "undefined reference to QObject::"  

Do I have to rebuild every depending library with gcc 3.0.4 or what is wrong ?


Best regards,
Jarmo
