problem with math.h 's function in Eclipse

Hi LETS,

I try to read differents posts on the web like:

http://stackoverflow.com/questions/7824439/c-math-linker-problems-on-ubuntu-11-10

http://stackoverflow.com/questions/16344445/im-using-math-h-and-the-library-link-lm-but-undefined-reference-to-pow-st

http://stackoverflow.com/questions/8480013/eclipse-c-c-cdt-add-l-option-linking-math-module-gcc-lm

The generated Makefile seems to be good because Eclipse places the -lm argument at the end...

I'm now installing Quartus 13.0sp1 to see if the problem persists.
