Instance Method Details

#cargo_target_path(profile, *path_components) ⇒ Object

Due to the lack of cross-compilation support, thermite assumes the resulting binary is placed in target/<profile>, however it’s actually in target/<target_arch>/<profile>

  target_base = ENV.fetch('CARGO_TARGET_DIR', File.join(rust_toplevel_dir, 'target'))
  File.join(target_base, ENV.fetch('CARGO_BUILD_TARGET', ''), profile, *path_components)

def dynamic_linker_flags
  @dynamic_linker_flags ||= begin
    default_flags = RbConfig::CONFIG['DLDFLAGS'].strip
    if target_os == 'darwin' && !default_flags.include?('-Wl,-undefined,dynamic_lookup')
      default_flags += ' -Wl,-undefined,dynamic_lookup'
    end
    default_flags
  end
end

#target_arch ⇒ Object

Thermite doesn’t support cross-compilation so it always assumes the binary is being built for the current architecture. It only really affects the name of the tarball.

Use the same target for all darwin versions
