Re: Doubt about plotting on MAC OS X Catalina

[Peter Teeson]

Hi:

The Macintosh operating system used to be called OS X 

Then it was renamed macOS. That was around the time Apple created a spin off iOS for their mobile devices.

So these days people refer to the hardware as Macs (both desktop and laptop)

And iPhone, iPad, iWatch for their mobile devices.

What make of Mac do you have? What version of macOS?

If you have questions I will try to help.

Hi,

there is a very nice description of how to install GNU APL on Macintosh written
by Peter Teeson. You can find in in the HOWTOs directory.

I don't know if Macintosh uses OSX, but Peters document is anyhow worthwhile reading.

BTW I have updated the ⎕PLOT error message to be more specific as to which library is missing.

Best Rgeards,

Thanks; I need to completely read the GNU-APL DOC, sorry about that

You are right the problem is with the libxcb.

⎕plot 1 2 3 4 5

SYNTAX ERROR+

      ⎕PLOT 1 2 3 4 5

      ^

      )MORE

⎕PLOT is not available because either no libxcb library was found on this

system when GNU APL was compiled, or because it was disabled in ./configure.

Exist a tutorials for building gnu-apl in OSX

Thanks for your time

Hi Toni,

the + character after SYNTAX ERROR (or any other APL error) indicates that there
is more information available regarding that error. The additional information
can be displayed with command )MORE.

I suspect that in this particular case libraries needed for plotting (essentially libX11.so,
libxcb.so, and libX11-xcb.so) were missing on the platform where GNU APL was compiled
(i.e. your own machine if you compiled from source or the build machine of a package if
you installed a binary package).

For ⎕PLOT to work, you may need to compile the interpreter from source with the required
X libraries installed beforehand.

Thanks for this awesome software. I have installed gnu plot 1.8 from brew package. It works well, and good integration with emacs. So it is a good environment for learning APL.

The only think is that when I try to plot I always get the following error:

       ⎕PLOT 0 1 ¯1 2 ¯2 3 ¯3
SYNTAX ERROR+
      ⎕PLOT 0 1 ¯1 2 ¯2 3 ¯3
      ^

I do not see anywhere, if is needed to load a workspace, or the needed for some environment configuration during installation. So really I do not know how to proceed.

Thanks for your time
