[Plplot-devel] I am stumped with -dev tk problem on AT, but I am strongly inclined to go ahead with the merge in the next 24 hours anyway

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

I get the following error messages if I attempt to use -dev tk with the
AT branch:

./x10c -dev tk -debug
plLoadDriver: Device not loaded!
plLoadDriver: tag=tk, drvidx=14
plLoadDriver: Trying to load tkd_drv.so on /usr/local/plplot_at/lib/plplot5.1.0/data/../drivers/tkd_drv.so
tcl_cmd: Evaluating command: rename exec {}
tcl_cmd: Evaluating command: set client_name [winfo name .]
tcl_cmd: Evaluating command: plclient_init
TCL command "plclient_init" failed:
         invalid command name "plclient_init"
tcl_cmd: Evaluating command: plclient_link_end
TCL command "plclient_link_end" failed:
         invalid command name "plclient_link_end"
Segmentation fault

In contrast, here is what I get with the MAIN branch:

./x10c -dev tk -debug
plLoadDriver: Device not loaded!
plLoadDriver: tag=tk, drvidx=13
plLoadDriver: Trying to load tkd_drv.so on ./drivers/tkd_drv.so
plLoadDriver: Local dlopen failed because of the following reason:
./drivers/tkd_drv.so: cannot open shared object file: No such file or directory
plLoadDriver: Trying to load at /usr/local/plplot_main//lib/plplot5.1.0/data/../drivers/tkd_drv.so
tcl_cmd: Evaluating command: rename exec {}
tcl_cmd: Evaluating command: set client_name [winfo name .]
tcl_cmd: Evaluating command: plclient_init
init_server: tk.c -- PID: 30164, PGID: 30164, PPID: 21452
argument list:
   plserver -child -e plserver_init -file /dev/null -name x10c -client_name tk (null)


It looks to me that the AT branch version is executing tcl commands fine
(the rename and set client... commands returned without error),
but there is some error when attempting to even get to plclient_init which
resides in plclient.tcl.  I placed a puts stderr message in
the very top of plclient_init for both systems, and it printed that
message fine in the MAIN version, but never reached it in the AT version.

So somehow, the AT version is having trouble finding plclient.tcl.

Note, there have been some recent MAIN updates to tcl which I
do not have in the AT branch (which was split off from MAIN about a week ago)
so that may be part of the problem.

Since this is the only driver that doesn't work, and the tkd_drv.so shared
object works fine when used by plserver or if loaded by wish, I am strongly
inclined to just merge AT into the MAIN branch tomorrow, and let the tcl
experts here deal with any remaining tk device problems while I get on with
autotools support for octave, static drivers, etc. on the MAIN branch.

I won't be doing the merge immediately this morning (Monday morning Pacific
time = UTC-8) because there are still some loose ends to tie up, and I want
to get some sleep so I will be fresh. But I do expect to do the merge some
time in the next 24 hours.
