Please state the version of valgrind/cachegrind and the processor architecture
(x86_64, etc.) that you are using.
How do you know that there was a problem? Please display the error messages
or describe the symptoms. Please display the linking command that was used.
In any case, using a shared library (libm.so) won't work.
Did you try naming the archive library (libm.a) explicitly?
gcc ... *.o /lib64/libm.a ...
