dlang调用其他文件中的函数失败 [英] dlang call to function in other file fails

问题描述

我正在测试使用D代码
调用其他文件中的函数的问题。我的问题是我收到错误消息，我不理解服务器中的$ b $b。d

I'm testing to make calls to functions in other files using D code My problem is that I receive errors I don't understand in server.d

import std.stdio;
extern (D) void otherFunction();
main(){
otherFunction();}

以及在客户端中。 d

and in client.d

import std.stdio;
void otherFunction(){ writeln("hello world");}

dmd服务器.d呈现此输出错误

"dmd server.d" renders this output error

Undefined symbols for architecture x86_64:
  "_D6server13otherFunctionFZv", referenced from:
      __Dmain in server.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Error: linker exited with status 1

有什么主意我打不通吗？
哦，我在OS X 10.9上
并且只要函数与main（）
/ a

Any ideas why I can't make the call? Oh I'm on OS X 10.9 And the call work as long as the function is in the same file as main() /a

推荐答案

D像C ++一样会破坏所有符号名称。
除非模块名称匹配1：1（您不应该这样做），否则诸如函数之类的符号将不匹配。

D like C++ mangles all symbol names. Unless the module name matches 1:1 (which you shouldn't do) then a symbol such as a function won't match up.

如果确实非常需要此功能，请切换到 extern（C），它会按您的预期工作。

If you really really need this, switch over to extern(C) which work as you're expecting.
