How do you statically link a c library in go using cgo?

Question

So there\'s a bunch of stuff on the group that suggests you can do this in go (although not on the cgo documentation):

package bridge

import \"fmt\"

// #cg         


        

Answer 1

A straightforward Makefile to link Go code with a dynamic or static library:

static:
    gcc -c gb.c
    ar -rcs libgb.a gb.o
    go build -ldflags "-linkmode external -extldflags -static" bridge.go

dynamic:
    gcc -shared -o libgb.so gb.c
    go build bridge.go

Directives in bridge.go:

/*
#cgo CFLAGS: -I.
#cgo LDFLAGS: -L. -lgb
#include "gb.h"
*/
import "C"
