compilation error   
I have included 'math.h' header file however when I try to compile the source I am getting the following error(I have 
given the proper search path also)

1. undefined reference to `_FLog'
2. undefined reference to `powf'

Any idea why is this happening and how we can resolve this ?

Re: compilation error   
You need to link against the math library. Add -lm to your link line.

Re: compilation error

Re: compilation error   
He just did.

The name is "libm.so". (hence -lm).

Re: compilation error   
M.  As I said -lm.. -l is the switch to link against libraries.
