Compiler/TMS320F28022: cannot find pow, sin, cos... I have math.h included

Tool/software: TI C/C++ Compiler

CCSv6 Win7 SP1 32 bit.

I want to use the pow() function (also sin, cos, sqrt) (in the software floating point lib), but the compiler says "pow declared implicitly".

I have included math.h, and the compiler does find that.

Any ideas?

thanks, Mark.
