Dyalog APL could not initialise

Postby ESgt on Mon Nov 25, 2019 1:02 am

Can you help me with this please?
After trying to install Dyalog APL on my RaspberryPi under Rasperian Stretch OS many times, I cannot get it to run right. The programming menu call-up doesn't work. Typing dyalog in a terminal gives: "Dyalog APL could not initialise". It will only run in a terminal with superuser mode. There is no ride-4.2 interface, although that is installed too.

Hi there

It's always a good idea to try starting APL from a terminal window (on non-Windows platforms that is) just to eliminate RIDE being a problem .. you can almost always type ")off" !

I suggest opening a terminal window and moving .dyalog to another name and trying again. If that doesn't work, can you send support@ an email with the full error message and also the output of "echo $?" immediately after APL has failed to start.

Once we get to the bottom of this we'll update this thread with a summary of the problem just so others can fix it quickly should they have it.

Its like this:
pi@raspberrypi:~ $ dyalog # In a terminal as Menu>Programming
# >Dyalog APL (TTY) does nothing
Dyalog APL could not initialise. # This IS the error message
pi@raspberrypi:~ $ echo $? # As suggested
1 #
pi@raspberrypi:~ $ sudo su #
root@raspberrypi:/home/pi# dyalog # Starts only as superuser
Dyalog APL/S Version 17.1.37241
