[Octave-bug-tracker] [bug #56900] Octave hang in "linux on dex" on samsung tablet

[Mike Miller]

Follow-up Comment #3, bug #56900 (project octave):

I think you are running into what looks to be a fairly common and well known
problem (that I just found with a few minutes of googling), Android does not
support System V shared memory, such as shmget, shmat, etc.

Qt image functions seem to require System V shared memory when running on
X11.

You can try preloading a library that provides these functions, for example
https://github.com/pelya/android-shmem or
https://github.com/termux/libandroid-shmem.

You can also try gnuplot with a different terminal, for example "setenv
GNUTERM x11".

However you decide to proceed to get graphics working on your system, you're
basically heading into uncharted waters, so good luck. You might want to
consider writing up a set of build and configuration notes on the Octave wiki
specific to this system.
