Can only start program from console, link doesn't work.

longblock454 · 02-02-2005, 04:04 PM

I am trying to create a link in Gnome to start the APC Powerchute application. If I start it from the console I have no problems:

[root@WindozeSucks ~]# cd /usr/lib/powerchute
[root@WindozeSucks powerchute]# ./xpowerchute

This works perfectly.

But if I create a link in Gnome, and add the text "/usr/lib/powerchute/xpowerchute" in the "Command:" box the application seems like it is going to start, ie the expanding boxes, then nothing! I have also tried the "Run in terminal" check box with no luck either. Any other variation results in an error that says "No such File or Dectory".

Thanks, Andy.

what happens if you set the link / run application to run:

Code:

cd /usr/lib/powerchute && ./xpowerchute

maybe it just needs to "be in the right path"?

Another scenario is, does it need to be run as root? in your console example you run it as root, as in your buttons you most likely run it as a normal user..
if you need it to run as root, you could use a utility like kdesu or similar to achieve the run as root.. I aint that familiar with gnome

Thanks, if i run

[root@WindozeSucks powerchute]# cd /usr/lib/powerchute && ./xpowerchute

No problems.

If I put "cd /usr/lib/powerchute && ./xpowerchute" into the command: box of the link launcher I receive "Details: Failed to execute child process "cd" (No such file or directory).

If I try "/usr/lib/powerchute && ./xpowerchute" in the command: box I receive "Details: Failed to execute child process "/usr/lib/powerchute" (Permission denied)".

Maybe you are correct about the user rights of the Gnome launcher?

do you have /usr/lib/powerchute in your PATH?

as root:

ln -s /usr/lib/powerchute/xpowerchute /usr/bin/xpowerchute and see if that helps

or

export PATH=$PATH:/usr/lib/powerchute

note that the second solution will need to be added to your .bashrc or /etc/bashrc or /etc/profile for it to be permanent

mm.. seems like the gnome run thingy aint as smart as kde:s.. Soo, the easiest way to fix it would prolly be to create a simple shellscript and then run that with the button.. like this /home/user/scripts/powerchute.sh which would have the following in it:

Code:

#!/bin/bash
cd /usr/lib/powerchute
./xpowerchute
exit 0

That would fix the possible error situation what stupid apps run accross when they think they will allway be run as ./ instead of a full path..

As for the running as root, kde:s "icons" and menu-editor have an option to run the thing as a different user, maybe gnome has something dimilar? assuming you actually need to run it as root

it wouldn't work in kde/gnome/anything if /usr/lib/powerchute is not set in PATH. All it will do is silently fail with a command not found....

imho PATH only matters when running it without the full path. If we use a full path when running and the target is executable, there should be no problem in a normal system.. If the problem was that it wouldnt run when typing "xpowerchute", then it would be related to PATH

__J · 02-02-2005, 04:43 PM

oops, forgot the whole path was put in the command box

Thanks for the reply, that sure did sound good, but I received the same "Details: Failed to execute child process "/home/powerchute.sh" (Permission denied)"

Thanks, Andy

did you make the script executable?

Artanicus · 02-02-2005, 04:51 PM

sure sounds like it needs to be run as root.. Well, if yore willing to settle for a bubblegum solution, lets modify the script abit.. (;

Code:

#!/bin/bash
su -c "cd /usr/lib/powerchute && ./xpowerchute"
exit 0

And set the box to run it in a console.. Then itll ask you for your password, and then execute it as root.. Worth a try.. (:

Artanicus · 02-02-2005, 04:56 PM

oh yeah, and as mr J said,

Code:

chmod +x powerchute.sh

helps the process alot.. The talk about child process led me to think the wrong way.. (:

Setting the permissions below did the trick on the link, thanks for the help. I learned quite a bit with all the help!
