8129 :: Build a Universal macOS Nim binary

• matthesoundman (orginal) [2021-06-18T23:53:03+02:00] view original

  Hello, I am a relatively new Nim user who is seeking information that might layout a sequence of steps to build a macOS universal binary. I have reviewed some of the documentation about the compiler regarding Cross-compilation, but am struggling a bit on what steps to take.

  Does anyone have any guidance or advice on how to do this?

  Thank you kindly :-)

  Here's one way, using NAKE (from Nimble):

  import nake
  
  const
    ExeName = "hello"
    ArmExe = ExeName & ".arm64"
    X64Exe = ExeName & ".x64"
    LipoExe = "/usr/bin/lipo"
    ArmFlags = "-l:'-target arm64-apple-macos11' -t:'-target arm64-apple-macos11'"
    X64Flags = "-l:'-target x86_64-apple-macos10.12' -t:'-target x86_64-apple-macos10.12'"
  
  task "universal", "Create Universal Mac Binary (M1/Intel)":
    if shell(nimExe, "c", ArmFlags, "-d:release", "-o:" & ArmExe, ExeName):
      ## do something useful here?
    if shell(nimExe, "c", X64Flags, "-d:release", "-o:" & X64Exe, ExeName):
      ## do something useful here?
    if shell(LipoExe, "-create", "-output", ExeName, ArmExe, X64Exe):
      removeFile ArmExe
      removeFile X64Exe
  Run

  Of course change the 'ExeName' constant to the name of your source file (without the .nim extension).

  Hope this Helps!

  AIR.
