Re: [Plplot-devel] tkwin.c is now split and I have also reorganized the linking on Linux

[Alan W. I. <ir...@be...>]

First, thanks for the plplotter.c changes.  It now compiles without the fatal
error (but with the warnings as you suggested would occur for tcl8.3).  I
did the usual wish test in the plplot/tmp area, and it worked fine.

Second, I then installed everything.  Also I created a symbolic link so that
ls -l /usr/local/plplot/lib/libtkwind.so
lrwxrwxrwx    1 software software       55 Aug  5 11:27 /usr/local/plplot/lib/libtkwind.so -> /usr/local/plplot/lib/plplot5.1.0/drivers/tkwind_drv.so

I then changed your latest pkgIndex.tcl so the two relevant lines read

grep libtkwin /usr/local/plplot/lib/plplot5.1.0/tcl/pkgIndex.tcl
        set file [file join $dir ../.. libtkwind[info sharedlibextension]]
	set file [file join $dir ../.. libtkwind[info sharedlibextension]]

(Note the "d" suffix has nothing to do with debugging so more changes are
required in this file.  Instead it marks the libraries and drivers as
double-precision versions (which is the case for me.  Nevertheless, let's
not worry about it for now.  I can just hack this to do what I want locally
for now, and we can figure out the configuration issues later.) For example,
I added an extra "../" and dropped drivers from the list of joined symbols
because I wanted to point to the symlink above in /usr/local/plplot/lib.

However, no matter how I fiddle with these two lines, I always get
the following error message:

wish
% set autopath /usr/local/plplot/lib/plplot5.1.0/tcl
/usr/local/plplot/lib/plplot5.1.0/tcl
%  package require Plplotter
can't find package Plplotter

As far as I can see the above set file command should work (and many other
variants I tried), but I think it is never being executed.  As an experiment
I put in a puts $file command in
/usr/local/plplot/lib/plplot5.1.0/tcl/pkgIndex.tcl, but package require
PLplotter never output that value of the file variable.

Perhaps autopath does not work like you thought? If I attempt to puts
$autopath from wish before I define it above it tells me it is undefined.
