Unable to run Golang application on 32-bit machine

php editor Yuzai pointed out that recently some users reported the problem of being unable to run Golang applications on 32-bit machines. After investigation, it was found that this is because the Golang language was originally designed to run on 64-bit systems, and the address space of 32-bit systems is limited and cannot meet the needs of Golang. Therefore, if you want to run Golang applications on a 32-bit machine, you may want to consider upgrading to a 64-bit system, or use other programming languages ​​​​that are suitable for 32-bit systems to develop applications.

Question content

I built Golang as a 32-bit version on a 64-bit machine. However, it has a problem, when I build like this, it gets the "kernel32.dll" in the SysWOW64 folder, but when I run it in a 32-bit machine (Windows 7). It doesn't have a SysWOW64 folder, so it returns the error:

Fatal error: kernel32.dll not found

This is my go build command:

go build -ldflags "-s -w"

This is my environment:

set GO111MODULE=

Can anyone suggest me a solution?

Workaround

According to phuclv's answer: "SysWOW64 is a 32-bit System32 on 64-bit Windows. 32-bit applications have to use %windir%\System32 All access to will be redirected to %windir%\SysWOW64."

So I think in your case you need to build a 32 bit machine (or virtual machine) and then copy and build your code over there. Of course, you'll have to downgrade some libraries to match the operating system, which can be challenging sometimes.
