Instance Method Details

#compile_code(code, *args) ⇒ Object

compile_code: String -> CompilationResult

Compile the given string and return compilation statistics.

This method has the same behavior as compile_file, except the code is given as-is instead of being in a file. Either this method or compile_file must be implemented in subclasses.

# File 'lib/benchcc/compiler.rb', line 76

def compile_code(code, *args)
  tmp = Tempfile.new(["", '.cpp'])
  tmp.write(code)
  tmp.close
  compile_file(tmp.path, *args)
ensure
  tmp.unlink
end

#compile_file(file, *args) ⇒ Object

compile_file: Path -> CompilationResult

Compile the given file and return compilation statistics.

Additional compiler-specific arguments may be specified.

A CompilationError is be raised if the compilation fails for whatever reason. Either this method or compile_code must be implemented in subclasses.

Raises:

  • (ArgumentError)
