problem running Version 17.0
Hi
I have Dyalog 16 on my RPi ZERO, and today tried to upgrade to 17.
The upgrade to (17.0.35466) appears to be OK and I can run it with
and I see 17.0.35466 start up.
However, starting up Dyalog via the command
still starts up version 16.0.35315
How can I get the command "dyalog" to run 17.0?
Thanks
Ray

Hi Ray
What command(s) did you run to update from 16.0 to 17.0 ?
Had you altered /usr/bin/dyalog at all ?

Hi Andy,
I have now (just before you replied) got round the problem.
I have modified the line in /etc/alternatives/dyalog
to read
and this seems to have done the trick.
I assume part of the upgrade to 17.0 on my Pi ZERO failed. There were some error messages relating to Miserver 4.1 displayed during the
I have NOT altered /usr/bin/dyalog.
Do you want any more information, and do I need to do any thing else?
Thanks

Re: problem running Version 17.0
Ray and I have corresponded further about this. We're not entirely sure what happened, but I have learned that you should never edit /usr/bin/dyalog on Linux/Pi. Linux has a system which allows you to select which of several different versions of selected files you want to use - the update-alternatives system.
If on Linux/Pi you wish to alter which version /usr/bin/dyalog points to, simply run
It is never a good idea to edit the mapl script in the Dyalog installation directory .. we recommend either taking a copy of mapl editing that, or writing your own script and pointing to $DYALOG/mapl .. actually, it's never a good idea to edit any file in any Dyalog installation .. we might overwrite it in the next patch (and this is likely to be true of Dyalog on Windows in the not too distant future too).

sudo update-alternatives --config dyalogand select the version that you wish to run.
