编译为 x86 时检测 OS x86 或 x64 [英] Detect OS x86 or x64, when compiled as x86

问题描述

我开发了引导软件来启动我的游戏.我用 Go 做到了这一点.跨平台对我来说尤其重要.另外，我不想将下载链接分成两个 x86/x64.我想在一个输出中处理所有事情.这就是我必须编译到 x86 的原因.当我这样做时，我无法正确检测到操作系统是 x86 还是 x64.

在编译为 x86 的软件中，我如何正确检测操作系统 x86 或 x64(在 Go 中).

编译为 x86 时，此代码不正确.

const is64Bit = uint64(^uintptr(0)) == ^uint64(0)

解决方案

Windows 你可以调用IsWow64Process来判断你是否是运行在64 位操作系统.请注意，如果您是在 64 位操作系统上运行的 64 位进程，它会返回 false，但如果您正在运行 64 位进程，那么您就知道该操作系统是 64 位的，否则它不会运行.

另请注意，32 位 Windows 已过时.微软已经在逐步停止对 32 位 Windows 的支持——他们没有不再希望在新计算机上安装它.

在 Linux 上你可以调用 uname 并查看 machine 字段.这是可能值的列表.请注意，它们中的大多数与您的程序不兼容，只有 i386、i686 和 x86_64.

I developed bootstrap software to start my game. I did this with Go. It was especially important for me to be cross-platform. Also, I didn't want to divide the download links into two as x86 / x64. I wanted to handle everything in one output. That's why I had to compile to x86. When I do this, I cannot properly detect that the operating system is x86 or x64.

In a software compiled as x86, how can i properly detect operating system x86 or x64 (in Go).

This code is not correct when compiled as x86.

const is64Bit = uint64(^uintptr(0)) == ^uint64(0)

解决方案

On Windows you can call IsWow64Process to determine whether you are a 32-bit process running on a 64-bit OS. Note that it returns false if you are a 64-bit process running on a 64-bit OS, but if you have a 64-bit process running, then you know the OS is 64-bit or it wouldn't run.

Also note that 32-bit Windows is considered obsolete. Microsoft is already phasing out support for 32-bit Windows - they no longer want it to be installed on new computers.

On Linux you can call uname and look at the machine field. Here's a list of possible values. Note that most of them won't be compatible with your program, only i386, i686 and x86_64.
