Unfortunately, I don't see Replicant, nor Free Phones, becoming mainstream
any time soon. What kinds of phones with free operating systems do exist? [1]
* Hardware built by large companies, OS provided by large companies:
  - Only Samsung with Tizen, but it is no longer being sold.
* Hardware built by large companies, OS provided by hackers:
  - Replicant. But all models after the original Galaxy S3 (from 2012)
    have a highly integrated modem chip from Qualcomm that contains a universal
    backdoor and therefore cannot be enabled in Replicant [2].
* Hardware built by small companies: does not have the integration level
  and therefore not the expected combination of weight + battery time
  that other phones have. Additionally, the UI part of the OS will be
  the major challenge.

OK, but that doesn't mean building clisp "for Android". It means
building clisp for use within a specific text-mode emulation app
on Android, in a way that cannot ever be useful for creating UI apps
on Android. I won't invest time in it.

You said compiling "on Android"; technically this is correct, but
nevertheless misleading.

This platform should be similar enough to Unix systems that any
single person can do this port in a short time, with some #ifs in
the source code. Good luck!

IMO a much better starting point for doing Lisp on Android is Clojure,
because it's based on Java and therefore integrates with the UI libraries
of Android. [3][4][5]
