  • Zenos OS

Build process
  1. Build Zenos OS C# Components
  2. Build Native ZenosOS object files(ILCompiler)
  3. Build Assembly components
    • multiboot_header
    • boot
    • OS.obj
    • modules
    • dotnet
    • load_end_addr
  4. Link all object files
  5. Build ISO

Listing symbols:

readelf -s ./sdk/libPortableRuntime.a
nm -g ./sdk/libPortableRuntime.a

investigate OSGroup=AnyOS in corert https://github.com/dotnet/corert/blob/c57237f6b22f58e037b6f316ebc138e8fa5833f6/dir.props

should be able to run ./build.sh clean Release anyos

should be able to add /p:DefineConstants="MYSYMBOL1;MYSYMBOL2" to the above with the appropriate constants

GOALS:

  • blockers:
    • erroring on some unimplemented methods
  • get internalsvisibleto working so that we can access the inner types
  • see if we can get a build more aligned with a CUSTOM OS
    • to get anyos working we would need to define some types or stubs for several classes
