Mastering Go - Second Edition

Mixing Go and C code

Now that you have the C code and the Go code, it is time to learn what to do next in order to execute the Go file that calls the C code.

-rw-r--r--@ 1 mtsouk  staff  162 Jan 10 09:17 callC.c
-rw-r--r--@ 1 mtsouk  staff   89 Jan 10 09:17 callC.h
$ gcc -c callClib/*.c
$ ls -l callC.o
-rw-r--r--  1 mtsouk  staff  952 Jan 22 22:03 callC.o
$ file callC.o
callC.o: Mach-O 64-bit object x86_64
$ /usr/bin/ar rs callC.a ...
