// foo.h int count;void foo(); //foo.c#include "foo.h" int count = 6;void foo() {    printf("I am foo!\n");} 

 

//foo.gopackage main // #cgo LDFLAGS: -L ./ -lfoo// #include <stdio.h>// #include <stdlib.h>// #include "foo.h"import "C"import "fmt“ func main() {    fmt.Println(C.count)    C.foo()}

使用靜態庫$> gcc -c foo.c$> ar rv libfoo.a foo.o

[diego@localhost ~/GoWork/src/applycation/testCgo]# go build foo.go[diego@localhost ~/GoWork/src/applycation/testCgo]# ./foo 6I am foo!
