gcc compile error

I'm a linux newbie user and I'm trying to compile a source code (not made by me) with g77

g77 -c -O3 reac.f
g77 -c -O3 poten.f
g77 -c -O3 ffopt.f
g77 -c -O3 shanno.f
g77 -c -O3 version.f
g77 -c -O3 vibra.f
g77 -c -O3 blas.f
g77 -o reac reac.o poten.o ffopt.o shanno.o version.o vibra.o blas.o
/usr/bin/ld: cannot find -lgcc_s
collect2: ld returned 1 exit status
makefile:11: recipe for target 'reac' failed
make: *** [reac] Error 1

This is the error I want to solve. I've already googled a lot, and done what they say.

But it didn't work.
