在C程序中链接C ++函数 [英] linking C++ functions in a C program
问题描述
大家好，我正在尝试编译一个C ++函数，然后从
a C程序调用它。
由于谷歌是我的朋友我已经结束了直到这个链接看起来非常清楚：
http://www.parashift.com/c++-faq-lit...c-and-cpp.html
不幸的是它不起作用。
这就是我在做的事情：
--------------- --------------------------
//main.c
#include" mylib.h"
int main（int argc，char * argv []）{
foo（）;
返回0;
}
-------------------------- ---------------
//mylib.h
#indef __cplusplus
externC{
#endif
void foo（）;
#ifdef __cplusplus < br $>
}
#endif
------------------------ -------------- ---
//mylib.cc
#include< iostream>
#include" mylib.h"
using namespace std; //不知道为了什么！
void foo（）{
cout<<"" Hello World！\ n";
}
---------------------------------- -------
非常感谢任何建议。

Hi everyone, I''m trying to compile a C++ function and then call it from
a C program.
Since Google is my friend I''ve ended up to this link which seems very clear:
http://www.parashift.com/c++-faq-lit...c-and-cpp.html
Unfortunately it does not work.
Here is what I''m doing:
-----------------------------------------
//main.c
#include "mylib.h"
int main (int argc, char *argv[]){
foo();
return 0;
}
-----------------------------------------
//mylib.h
#indef __cplusplus
extern "C"{
#endif
void foo();
#ifdef __cplusplus
}
#endif
-----------------------------------------
//mylib.cc
#include <iostream>
#include "mylib.h"
using namespace std; // don''t know what for!
void foo(){
cout<<"Hello World!\n";
}
-----------------------------------------
Thanks a lot for any suggestion.

如果你遵循所有积分就行。前两个经常被忽视。
It does if you follow all the points. The first two are often overlooked.
