我在尝试着在 CygWin 64 位上编译（假定）32 位网络唤醒工具这里由 Thomas Krennwallner 创建，应该编译在 Unix 和 Windows 上的 CygWin 下。
下载后我做了：
tar -zxvf wol-0.7.1.tar.gz
并且，为了更新其 configure.guess 脚本（包含的脚本有点旧：来自 2004 年），我从这里。
因此，根据其README文件，我这样做：
./configure
我得到：
Luis@Windu /cygdrive/h/Temporal/wol/wol-0.7.1
$ ./configure

这似乎是在报告预期的问题时在 64 位上编译 32 位程序平台。
是否有可能解决这个问题?
我读过一些关于在 gcc 编译器上使用标志“-m32”或在编译之前发送一些变量（导出）的信息，但问题似乎出在配置部分，而不是编译部分。顺序似乎是：
- 。配置
- 制作
- 进行检查
- 进行安装
- 使清洁
第一步失败了:-(。
无论如何，我尝试过：
export CFLAGS='-m32' export CXXFLAGS='-m32' export LDFLAGS='-m32'
但./configure剧本却不断失败。
顺便说一句，我试图忽略错误并继续（第二步）编译：
make
但它会产生一些错误消息报告（抱歉，我的 CygWin 似乎是西班牙语的），类似于No objective specified and no makefile found。
我认为解决这个问题可以帮助我学习如何在 CygWin 64 上编译 32 位程序。
请提供一些帮助。
PS：我知道这个工具有 Win32 版本可供下载，并且还有其他用于局域网唤醒的程序。但是如何解决问题呢？
编辑：我在 CygWin 上安装了以下软件包名称：
gcc-core
gdb
make
mingw-gcc-core
mingw-gcc-g++
mingw-w32api
编辑-2：我通过卸载 CygWin 64 位并安装 32 位版本节省了我的时间。一切都进行得很顺利。
答案1
Cygwin 软件包有两个版本：64 位版本和 32 位版本。由于 64 位库比 32 位库更新，因此缺少一些库和程序。
您可以同时安装 32 位和 64 位 Cygwin，不会出现任何问题。因此，如果您想使用 32 位模式进行编译和继续，请安装 32 位 cygwin 并调用其 bash shell。
Cygwin 32位通常安装在c:\cygwin，64位cygwin安装在c:\cygwin64。
总而言之，如果您需要 32 位功能，请安装 32 位 cygwin 和完成任务所需的所有必要软件包。
注意：32 位程序将在 64 位 Windows 平台上运行。
答案2
为了使以前的答案更加稳定和可信（我还不能评论），这是官方答案：
https://cygwin.com/ml/cygwin/2017-02/msg00038.html
“问：至少在我看来，‘gcc -m32’可以理解为‘在当前 ABI 环境 (cygwin64) 中创建一个使用 32 位架构的可执行文件’。
答：不，确实不能。-m32 的作用正如 GCC 文档所述：它使 GCC 生成 32 位 x86 代码。文档中没有任何内容表明此类代码在给定的 ABI 环境中确实可以运行。对于 Cygwin64 来说，它不能运行。
问：如何让 32 位编译后的 cygwin 程序在 cygwin64' 下运行？
答：您不能。其他人也不能。对于基于 Cygwin64 的程序，Cygwin32 是一个真正的交叉编译平台，而不仅仅是同一平台的某个子集。反之亦然。
