在C程序中链接C ++函数

本文介绍了在C程序中链接C ++函数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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 } #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。 Al Hi everyone, I''m trying to compile a C++ function and then call it froma 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 __cplusplusextern "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.

The first two are often overlooked. 这就是我正在做的事情： ------ ----------------------------------- //main.c #include" mylib.h" int main（int argc，char * argv []）{ foo（）; 返回0; } Here is what I''m doing:-----------------------------------------//main.c#include "mylib.h"int main (int argc, char *argv[]){ foo(); return 0;} 如何构建可执行文件？ - Ian Collins How are you building your executable? --Ian Collins Ian Collins写道： Ian Collins wrote: > 如果你遵循所有的观点就行了。前两个经常被忽视。 >It does if you follow all the points.
