package main   import "C"   func main() {}   //export Hello func Hello() string {     return "Hello" }   //export Test func Test() {     println("export Test") }

#include <stdio.h> #include "libgo4c.h" void main() {            GoString str;            str = Hello();            Test();            printf("%d\n",str.n);  }

build.sh

go mod init go4c
go build -buildmode=c-shared -o libgo4c.so lib.go

gcc main.c -o test -I./ -L./ -lgo4c
