I&#39;m not sure if you&#39;re talking about C++ ABIs or C ABIs?&nbsp; If you&#39;re already using a C ABI, and you&#39;re getting incompatibilities, well I have nothing useful to say :-) <br><br>If you&#39;re talking about C++ ABIs, technically it&#39;s possible to use a Generator to drop-down into a C ABI, pump across the interface at a C level, function by function, then wrap back into C++ classes.
<br><br>The advantage is that you decouple the classes on either side of the interface, so it&#39;s possible to add new methods to the classes without breaking anything.<br><br>(Warning: I have no idea to what extent what I just wrote relates to ghc etc.&nbsp; I did make a generator to cross a C++ ABI boundary before, to link an msvc C++ dll with a mingw C++ exe:
