I will try that
I Have tried this.
LIBRARY_PATH=/opt/X11/lib:$LIBRARY_PATH CPPFLAGS="-I/opt/X11/include" LDFLAGS="-L/opt/X11/lib" ./configure

Compiled and it worked finally de interpreter can find the X11 but now giving a segmentation fault:

      ⎕PLOT 1 2 3 4

Do you thing that adding the include files will help?

Hi,

too bad. How about /usr/local/include (and a bit olf luck that g++ knows it) ?

Hi,

so the headers are usable even though they don't exist. Interesting platform
that you have there. In that situation I would (recursively) copy the header files from
/opt/X11/include to /usr/include to make sure that they are found by both the
preprocessor and the compiler. If I remember correctly then apple does not
use the real g++ but a kind of emulation of it which might cause this kind of
problems.

Also have a look at config.log after ./configure; it tells you how the tests were compiled.

Best Regards,
Jürgen

Hi,

I would at least expect something like

 
CXXFLAGS="-I /opt/X11/include" ./configure

(if that is the directory where your header files live).

Best Regards,

I'm not sure where to point I have the X11 in my /opt/X11

Hi Antonio,

For X11 and friend to work you need two different things:

1. header files, e.g.
xcb.h, Xlib.h, etc.
2. library files, e.g. libxcb.so.1, libX11.so.6, etc.

These days libraries are often shipped in two different packages: one that
contains only the (shared) libraries and the other package contains the
corresponding header files. That second packages normally ends with "-dev".

For example (output from aptitude search libx11):

i   libx11-6                        - X11 client-side library
i   libx11-dev                      - X11 client-side library (development headers)

In your case the ./configure script cannot find the header files which means that either the  the -dev package
was not installed, or they were installed in an unusual place. In the latter case you can
tell ./configure where else to look, for example:

CXXFLAGS = -I /usr/somewhere_else ./configure [other configure options...]

Jürgen Sauermann

⎕PLOT is not available because one or more of its build prerequisites (in
particular libX11.so) was missing, or because it was explicitly
 disabled in ./configure.

But different from the first one, it was no libxcb library was found, I suspect that at this point I also need to change something in the configure in order to compile with X11

Hi again,

another thing that you may want to check is that your config.h (which is
generated by ./configure) contains the following lines:

/* Enable GNU extensions on systems that have them.  */
#ifndef _GNU_SOURCE
# define _GNU_SOURCE 1
#endif

Hi Antonio,

that seems to be an incompatibility between the commonly used libs and the Apple libs.
Nothing that I could (or should) do anything about in GNU APL. As far as I can see you could
probably remove the 
POLLRDHUP without much harm so that the offending line reads:

pfd.events = POLLIN;

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.

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

Exist a tutorials for building gnu-apl in OSX

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.
