Can't get GNU-APL to see it's Workspace Libraries (eg: wslib3, wslib4, wslib5)

[gemesys]

Hi;
I've downloaded the source and built the GNUAPL interpreter on a
CentOS-7.4 Linux box, and it seems to work quite well!

I'm using the GNUAPL 1.7 version, as 1.8 has been reported to segfault
by some other folks using this APL.

The apl-1.7 compiled and installed nicely, and runs well, if I

use:    xkbcomp  apl.xkb :0 -w 0
to set up the xterm display, and

then:   apl --noColor
to run the interpreter.

Really looks like it runs fine - except I cannot get GNUAPL to "see" it's
libraries, ie. wslib3, wslib4 and wslib5.

I've tried setting environment vars APL_LIB_ROOT and GNU_APL_LIBS to
various values (the build directory where the source is, or the
/usr/local/lib/apl directory where the installed binary and shared system
libraries are installed to, or a local user directory, etc.

The only APL "Library" that the interpreter is able to "see" is the one
called "workspaces" in either the source build directory, or a local user
directory.

What this means is that none of the examples, or SQL stuff, or HTML stuff
that is provided with the interpreter can be accessed, and none of the
scripts can be run.

All the files seem to be installed to the correct places - but the
compiled interpreter cannot "see" the workspaces, despite all the files
being installed to the correct directories:

When I run the APL interpreter,and enter ")libs", I get indication of
everything except "workspaces" is "MISSING":

(Here is what the APL interpreter reports: )

-------------- End Example GNUAPL Session ---------------------------------

This looks like a configuration issue, but I have not been able to track
it down, as the "./configure" and the "make" all ran fine.

Any ideas anyone???   Thanx for ideas, from anyone!
