There's no need for a base class, just a specification.
Please examine the following interface and see
a gcc implementation below that. At least criticize
the interface if you don't like it.

The interface:

# module 'interscript/compilers.c

class python_module:
  def __init__(self,**kwds):
  # initialise the object with kwds as configuration.
  
  def configure(self,**kwds):
  # extend or change configuration

  def compile(self,filename, **kwds):
  # compile the file, with given options
  # return the string name of the object file

  def link(self,modname, filenames, **kwds):
  # link the list of object files, with given options
  # to generate the named python module.
  # returns the name of the shared library

class application:
  # exactly the same, except produces an executable
  # tool that can be invoked from the command line

# module 'interscript/compilers.cpp
# exactly the same, except for C++
