## gcc sqrt math h

**Why am I getting "undefined reference to sqrt" error even though I ** - 6 Answers. The math library is named libm.so , and the -l command option assumes a lib prefix and .a or .so suffix. gcc (Not g++) historically would not by default include the mathematical functions while linking. It has also been separated from libc onto a separate library libm.

## sqrt function not working in gcc

**sqrt() function not working with variable arguments** - 8 Answers. You probably need to add -lm when you compile. When you take the square root of a constant, the compiler is optimizing the code by taking the square root while it compiles, so it doesn't use sqrt at all. Use the command gcc -Wall -o "test2" "test2.c" -lm which will likely fix this.
