c++ - 如何在 64 位 Windows 上使用 Cygwin 编译 32 位 C++ 程序

Question

我在 64 位 Windows 上运行 Cygwin。我想将我的程序编译为 32 位，所以我尝试用-m32标志编译我的程序，但它出现了这些错误。

collect2: error: ld returned 1 exit status

然后我尝试用 安装 Cygwin setup-x86.exe，但输出程序仍然是 64 位。

编辑： 我的来源包括这些指令。

#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <netdb.h>
#include <time.h>
#include <string.h>
#include <iostream>
#include <windows.h>
#include <ctype.h>
#include <thread>
#include <chrono>
#include <filesystem> 
#include <future>
#include <wchar.h>

基本上我想要一个适用于 32 位 Windows 的程序，但是有些指令只能在 Cygwin 中找到，所以我需要使用 Cygwin。
