*Antonio10ms$ gcc pi.c -o1 pi
ld: can't link with a main executable file 'pi' for architecture x86_64

I think you are confusing the optimization argument with the output/target argument.

I think what you want is

gcc pi.c -o1 -o pi

where "-o1" means "optimization level 1" and "-o pi" means "output to an executable named pi"
