[Octave-bug-tracker] [bug #47480] [octave forge] (io) relies on deprecated octave_config_info

[Mike Miller]

Follow-up Comment #14, bug #47480 (project octave):

There is no documented way at the moment for a user to ask Octave if it was
supposed to be built with Java support, whether or not the Java runtime is
found.

I can understand why this might be useful to help a user debug their
installation, it tells them whether they need to install Octave again or just
need to set JAVA_HOME or install a different JRE or something.

If this is specific to Java, because it relies on both compile-time features
and run-time environment, what if Octave itself provided a documented Java
diagnostic function that could report what is wrong with loading Java? This
could take some of the work off of the io package and provide uniform messages
for all packages and user code to rely on. If you agree we can move that to a
separate wishlist bug.
