c - 无法从 Ubuntu VM 交叉编译 C 程序以兼容 Windows 主机

Question

我在编译 C 程序并在 Windows 7 64 位计算机上运行它时遇到问题。

这是我的脚本:

#include <stdbool.h>
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[])
{
     bool isCaseSensitive = false;
     enum { CHARACTER_MODE, WORD_MODE, LINE_MODE } mode = CHARACTER_MODE;
     size_t optind;
     for (optind = 1; optind < argc && argv[optind][0] == '-'; optind++)
     {
         switch(argv[optind][1])
         {
             case 'h': isCaseSensitive = true; printf("Help page"); break;

         default:
             fprintf(stderr, "Usage: %s [-h]\n", argv[0]);
             exit(1);
        }
    }
}

首先，我在 Windows 7 主机上使用 Ubuntu 16.04 通过 vmware 编译此脚本。当我运行: gcc -m64 utilis.c -o utilis.exe 时，它将编译，但如果我在主机上运行它，则会收到此错误:

如果我尝试使用 32 位编译它，并让我的一个 friend 在他的 32 位计算机上运行它，我会得到以下结果:

/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.9/libgcc.a when searching for -lgcc
/usr/bin/ld: cannot find -lgcc
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.9/libgcc_s.so when searching for -lgcc_s
/usr/bin/ld: cannot find -lgcc_s
collect2: error: ld returned 1 exit status

如果我让他运行 64 位版本，他会收到此错误:

我尝试对此做的事情:

如何才能让我的程序正确编译并与我的 Windows 7 计算机交叉兼容？

Answer 1

明白了，需要安装mingw Linux 工具链。

sudo apt-get install x86_64-w64-mingw32-g++
e@ubuntu:/mnt/hgfs/devshare/utilis$ mg++ utilis.c -o utilis.exe --static
C:\Users\z-perkins-thomas\Documents\bin\testenv\devshare\utilis>utilis.exe -h
