Compile 32 bit binary on 64 bit system
提问by pluralism
I've coded a Go program in a 64 bit system but I want to compile a 32 bit binary!
我已经在 64 位系统中编写了一个 Go 程序，但我想编译一个 32 位二进制文件！
The 64 bit binary is working just great but I have no idea how to create a 32 bit binary.
64 位二进制文件运行良好，但我不知道如何创建 32 位二进制文件。
How can I do it?
我该怎么做？

If you built your Go from source, then you can build any additional compilers and libraries for any CPU and OS. If you are on windows/amd64 and want to build for windows/386, then this will build everything you need to compile for windows/386:
如果您从源代码构建 Go，那么您可以为任何 CPU 和操作系统构建任何额外的编译器和库。如果您在 windows/amd64 上并且想要为 windows/386 构建，那么这将构建您需要为 windows/386 编译的所有内容：
set GOARCH=386
cd %GOROOT%\src
make.bat --no-clean
Once you have done that, you can build your windows/386 executable with:
完成后，您可以使用以下命令构建 windows/386 可执行文件：
set GOARCH=386
cd %YOUR_PROG_DIR%
go build
Since you are on windows/amd64, you should be able to even run / test your windows/386 programs too. Just make sure to set GOARCH=386before you invoke any commands for windows/386.
由于您使用的是 windows/amd64，您甚至应该能够运行/测试您的 windows/386 程序。只需确保set GOARCH=386在为 windows/386 调用任何命令之前。
One caveat: this does not support cgo, so you cannot use any packages that use cgo.
一个警告：这不支持cgo，因此您不能使用任何使用cgo.

The way I have achieved this (without any compiling of the compiler) on my Windows 7 64 bit PC was first having the windows amd64 installed, then download 32bitzip and unpack to a second folder:
我在 Windows 7 64 位 PC 上实现这一点的方法（没有任何编译器编译）首先安装了 windows amd64，然后下载 32 位zip 并解压到第二个文件夹：
\go\go32
\go\go64
By then adjusting the PATHand the GOROOTinside my command prompt window as follows:
届时调整PATH和GOROOT我的命令提示符窗口中，如下所示：
set PATH=\go\go32;%PATH%
set GOROOT=\go\go32\
Then I went back and recompiled my app that was previously compiling using the 64 bit. All this can be setup in a batch if you want to switch between regularly.
然后我回去重新编译我之前使用 64 位编译的应用程序。如果您想定期切换，所有这些都可以批量设置。

Ok, I've finally solved the problem! Here it is how I did it(I was miserably failing actualy!).
好的，我终于解决了这个问题！这就是我是如何做到的（我实际上失败了！）。
- First thing I did was to download GCC from http://www.mingw.org/.
Next add C:\MinGW\bin to the PATH environment variable(I'm assuming that MinGW is installed in C:\MinGw)
Next thing before running go build/go install is to set the enviroment variables.
- Open the command prompt and go to C:\Go\src and run all.bat from the command line.
- Then you have to set GOOS, GOARCH and CGO_ENABLED to windows, 386 and 0 respectively!(you should also set GOPATH to the path where your current Go project is).
- Next run make.bat and make.bat --no-clean After that you can build your project for 32 bit systems! I hope this is helpful!
- 我做的第一件事是从http://www.mingw.org/下载 GCC 。
接下来将 C:\MinGW\bin 添加到 PATH 环境变量中（我假设 MinGW 安装在 C:\MinGw 中）
在运行 go build/go install 之前的下一件事是设置环境变量。
- 打开命令提示符并转到 C:\Go\src 并从命令行运行 all.bat。
- 然后你必须将 GOOS、GOARCH 和 CGO_ENABLED 分别设置为 windows、386 和 0！（你还应该将 GOPATH 设置为当前 Go 项目所在的路径）。
- 接下来运行 make.bat 和 make.bat --no-clean 之后你就可以为 32 位系统构建你的项目了！我希望这是有帮助的！

My Go version is 1.14 ,I change make.bat as follow:
我的 Go 版本是 1.14 ，我将 make.bat 更改如下：
:: if "x%GOROOT_BOOTSTRAP%"=="x" set GOROOT_BOOTSTRAP=%HOMEDRIVE%%HOMEPATH%\Go1.4
Change GOROOT_BOOTSTRAP to my Go's root:
将 GOROOT_BOOTSTRAP 更改为我的 Go 根目录：
if "x%GOROOT_BOOTSTRAP%"=="x" set GOROOT_BOOTSTRAP=D:\Go
after that I got this error
之后我收到了这个错误
go tool dist: unknown $goarch 386
then I set GOOS and GOARCH
然后我设置 GOOS 和 GOARCH
setlocal
set GOROOT=%GOROOT_BOOTSTRAP%
set GOOS=
set GOARCH=
set GOBIN=
set GO111MODULE=off
"%GOROOT_BOOTSTRAP%\bin\go.exe" build -o cmd\dist\dist.exe .\cmd\dist
endlocal
set GOOS AND GOARCH as follow
设置GOOS和GOARCH如下
setlocal
set GOROOT=%GOROOT_BOOTSTRAP%
set GOOS=windows
set GOARCH=386
set GOBIN=
set GO111MODULE=off
"%GOROOT_BOOTSTRAP%\bin\go.exe" build -o cmd\dist\dist.exe .\cmd\dist
endlocal
But I got error this is not a 32bit program.
但我收到错误，这不是 32 位程序。
