  }
end

#compile(options = {}, &block) ⇒ Object

Compiles the Program’ sources

Attributes

  • options - a Hash containing named options

  • block - if provided, a callback invoked when the Program is compiled. Signature of the callback is { |Program, Pointer to user_data| … }

Options

  • :device_list - an Array of Device to build the program for

  • :user_data - a Pointer (or convertible to Pointer using to_ptr) to the memory area to pass to the callback

  • :options - a String containing the options to use for the compilation

  • :input_headers - a Hash containing pairs of : String: header_include_name => Program: header

Returns:

  • size_t
