go - Cgo:抱歉，未实现:64 位模式未编译

Question

我目前正在尝试向我的 Go 项目添加一些 C 代码。没什么好看的

/*
#include <stdio.h>
void test() {
    printf("hooola")
}
*/

import (
    "C"
)

func MessageBox() {
    C.test()
}

但是这会返回

cc1.exe: sorry, unimplemented: 64-bit mode not compiled in

我检查了我的 g++ 和 gcc 编译器，一切似乎都很好，g++ -v 返回了这个

虽然 gcc --version 返回这个

两者都是使用 mingw64bits 安装的，所以我不确定我的问题出在哪里？

1. 简答:
   我尝试了很多版本，64 位 Windows 操作系统中 32 位和 64 位 go build 的唯一工作版本是 tdm64-gcc-5.1.0-2.exe (参见 tdm-gcc page)。
   您可以将其安装到 C:\TDM-GCC-64\ 并将 C:\TDM-GCC-64\bin 添加到您的 PATH (在顶部 = 或左侧)。

1. 你可以试试MinGW-w64 - for 32 and 64-bit Windows或者 x64-4.8.1-release-posix-seh-rev5 .
   此版本仅适用于 64 位构建(不适用于 64 位操作系统上的 32 位目标)。

---

1. 对于 Windows 操作系统，运行命令提示符:cmd(Linux 中的终端)然后运行此命令(Linux 中的whereis gcc):

   where gcc
   

   然后，如果有多个 gcc 路径，那么您可以编辑这些路径的顺序，将您需要的放在最前面，或者删除所有其他路径。
