Can not run Golang application in 32 bits machine

I build Golang to 32 bits version in 64 bits machine. However, it has a problem, when I build like that, it will take the "kernel32.dll" inside SysWOW64 folder, but when I run in 32 bits machine (Windows 7). It doesn't have the SysWOW64 folder, so its return an error:

fatal error: kernel32.dll not found

Here is my go build command:

go build -ldflags "-s -w"

Here is my go env:

set GO111MODULE=
set GOARCH=386

Can anyone suggest me a solution?

Solution

  • According to @phuclv answer:

    SysWOW64 is the 32-bit System32 on 64-bit Windows. All accesses to %windir%\System32 by a 32-bit application will be redirected to %windir%\SysWOW64.

    So I think in your case, you need to build a 32-bit machine (or virtual machine) then copy and build your code in there. Of course you will have to downgrade some library to match the OS and sometimes it could be challenging.
