Compile fyne application for Windows operating system, gcc_linux-amd64. c: 63:2: error: unknown type name 'sigset_t'

[lizhao-8202]

os:Win10 Professional Edition
go version： go1.19.1 windows/amd64

I plan to package the fyne code under Windows as a Linux version, but there is a compilation error. Related operations：
1、SET CGO_ENABLED=1
2、SET GOOS=linux
3、go build main/build_job.go

Error logs：

runtime/cgo

I want to know how fyne implements cross compilation on Windows machines

It looks like you don't have the C compiler for linux, it should be set with CC. https://docs.fyne.io/started/cross-compiling

If this sounds complicated you can use fyne-cross instead which containerises the whole setup for you.
