including files with Kdevelop

Hi,
I have recently installed Mandrake 10.0.
I am trying to compile my code using Kdevelop. It compiles for asimple "HEllo WOrld" code. But, when I include math.h and use a function (sqrt, pow), it compiles, but says undefined reference when tried to link it. I think it should be a simple switch - like including the library.

Someone please help me with this.

Regards,
Shyam Sundar

To use functions like sqrt you need to add '-lm' to the linking options: Project->Project options...->Configure Options and then add the flag to 'Linker flags (LDFLAGS)'
