[Openmcl-devel] Maybe a better way to delivery apps

[Dave Cooper]

Hi Mike et al,

The current ASDF provides 'asdf:monolithic-fasl-op.

I'm not sure if ASDF has or contemplates any automatic facility for
compressing/uncompressing fasls, but that might be something nice to have,
to be able to deliver a compressed monofasl and have the receiving end be
able to "play" it directly.

This all of course assumes that the receiving end already has compatible
CCL version installed (that's somewhat analogous assumption with JAR
files). Where the analogy falls apart, at least for CCL, is that any
delivered fasls will still be platform-specific (e.g. Mac, Windows, Linux)
unlike JAR files which are supposed to run unmodified on any underlying OS
platform.

I wrote up a little blog posting a while back with an example use of ASDF's
monolithic-fasl-op:

  http://gendl.blogspot.com

This is in need of some followup, but it introduces the basics and also
mentions the possibility of using the monofasl as a first step in preparing
a dumped executable image.


Regards,

 Dave
