Code:Blocks 13.12 can not recognize operator new () ?

[mxtsuper]

Hi.
I installed the CodeBlocks 13.12 on my PC (OS: ubuntu).
I have installed the gcc and g++.
I wrote some c++ code and built them.
The CodeBlocks gave  the errors:
undefined reference to `operator new(unsigned int).

Can somebody kindly help me to deal with the problem?
Tanks very much.
