Go Crosscompile

Explanation

symbol() function in pkg/mypkg/symbol_linux.go and symbol_windows.go is different. When running and building program, GOOS choses right one. for more information run these in cmd/app/ directory:

  go build .
  ./app
  # Output:
  #1+2=linux
  #a/b/c

---

  env GOOS=windows GOARCH=amd64 go build .
  ./app.exe
  # Output:
  # -Some random wine logs if running on linux with wine-
  #1-2=windows
  #a\b\c 

---

  file app*
  # see information about executables

HELP NEEDED

• VSCode gives redecleration error when using same name as function names. How to solve this? maybe see https://github.com/golang/go/issues/29202 ?
• see more in this doc

Before trying

• make sure you have installed wine in your linux system
  • or use a windows system too
