Hello All,

It was suggested by another member to post in this section.

Background:
We have some new machines where we are starting to install Slackware 14.1 that comes with Tcl 8.6. Our current running machines have Slackware 12.2 running a C program in conjunction with Tcl 8.5. We have copied this program to the new machine.

The issue is when we run the program the gui appears but function buttons on the gui do not operate, returning back to the console screen.

At first the program would not compile correctly stating errors on the console screen. With the help of the Forum (programming section) I was able to recompile with no errors.

When I attempted to run the program the gui appears but pressing a function button I got the following message on the console screen:

access control disabled, clients can connect from any host
alloc: invalid block: 0x8378e0: 0 0
bytex/go_bytex: line 4: 27901 aborted bytex
access control enabaled, only authorized clients can connect

It was stated by the member that this has something to do with x.

My experience is limited,thanks for any help!!

Jeff

you are on Slackware, have a started X session, XFCE, KDE, whatever
you have your program, which has compiled successfully

you are in a terminal, konsole, xterm, what ever
and you run the program by , you have not changed to an other users or use su,
and you are a user, not root?

what does this program do?

read about xhost

https://wiki.archlinux.org/index.php/Xhost

if you do not want to read, try
xhost +localhost

however, this should not be required and possible you have something wrong configured

Hi a4z,

I am logged under root and from the CLI, I type in "go_bytex" to start the program. In real
operation all assigned users, using there own password would be able to from multiple terminals get the same qui as the "root" user. We use KDE and when all is working correctly
we make a link between go_bytex and a icon off the KDE Desktop, eliminating the need to use the CLI.

That is another issue we are having because Slackware 14.1 also has a KDE upgrade and we
have a problem creating this link with it. One thing at a time however, go_bytex
should still execute from the CLI.

I vi go_bytex and added the localhost to xhost +. This caused a error stating "no protocol specified" with no gui at all. I changed it back and am back where I started from:
#!/bin/bash
xhost +
bytex
xhost -

I will check out your website but I need help, got to get this working!

Thanks.

Jeff

no protocol specified
sounds like you are not in a X session, or access via ssh, or h

you need to have a x session running,

start kde,
open a terminal (it is called console)
run your program as normal user

does it work?

Hi a4z

We are not at the point where we would add actual users. I am not clear about "start kde"?
When I login as root the KDE Desktop comes up then open up a terminal and enter go_bytex.

The "no protocol specified" message only appeared when I added localhost to xhost +;
xhost +localhost. I took this out and now have under go_bytex:
#!/bin/bash
cd /bytex
xhost +
bytex
xhost -

Thanks.

Regards,

Jeff
