1)swift,貌似官网的推荐
2)extern "C"
我使用后者,用起来比较爽,上代码
c.h
1 #pragma once 2 3 #ifdef __cplusplus 4 extern "C" { 5 #endif 6 void test(); 7 #ifdef __cplusplus 8 } 9 #endif
c.c
1 #include "cplus.hpp" 2 #include "c.h" 3 4 void test() { 5 A *a = new B(); 6 a->test(); 7 }
cplus.hpp
1 #pragma once 2 3 class A { 4 public: 5 virtual void test(); 6 }; 7 class B: public A { 8 public: 9 void test(); 10 };
cplus.cpp
#include <iostream> #include "cplus.hpp" using namespace std; void A::test() { cout << "a" << endl; } void B::test() { cout << "b" << endl; }
build.sh
1 g++ -o cplus.o -c cplus.cpp 2 g++ -o c.o -c c.c 3 ar r libc_test.so c.o cplus.o
test.go
1 package main 2 // #cgo LDFLAGS: -L . -lc_test -lstdc++ 3 // #cgo CFLAGS: -I ./ 4 // #include "c.h" 5 import "C" 6 7 func main(){ 8 9 C.test() 10 11 }
执行顺序
1 ./build.sh 2 go build test.go
