Are you sure the toolchain you're using is working properly?
The following test program should compile link and run ok:
--- test.c --
#include <math.h>
float x = 1.57f;
int main(void)
{
return (int)roundf(x) != 2;
}
----------
gcc -std=gnu99 -o test test.c -lm
A workaround might be to disable the ulink driver, if you don't need it.
