Not able to add program to startup

henfos · 06-21-2011, 07:13 AM

Made a little c-program i want to start at boot and found out that i can do that through the rc.local script that runs once every time the computer boots. Say that i have a program called test in /home/user/Documents... what do i write rc.local? Know nothing about scripting and i didnt understand what i read when i googled it :/

Just add a line to rc.local containing the full path to the program you want to run. For example, if I want to run /home/djshaji/Documents/personal/new/c-programs/bin/hello_world, I would simply put the entire path to the program in rc.local. No need to do any scripting.

On Gnome you could type

Code:

gnome-session-properties

in a terminal and then add the program you made to the list of Startup Applications.

This works on Gnome 2.30.2, don't know about the newer versions.

And thats what i thought, but when i do that and run the script directly or do a reboot my program never starts. I know because if it starts the first thing it does is write "test" to a textfile, and it runs perfectly if i just run the program directly.

btw. when i run the script in terminal i get segmentation fault...

lol, ill just continue to answer myself so you know where im at. So ive found out that there is no problem with the rc.local script, just that i get segmentation fault. What is this? I can run the applikasjon from window, but not through rc.local

Okei, i was a bit quick to push the solved button on my other thread so sorry for spamming the forum :P (Really noob

)
My program now starts during the boot through the use of rc.local, but its not still running when i login and check system monitor. My program is essentially an while-loop so it isnt quiting by itself.

Really you'd have been better to add to the orig qn I think.
Can you point at or describe/summarise the orig qn for me/us?

Edit: OK, just stumbled across it.

Basically

1. fix the segment violation
2. the entry in rc.local should like something like this

Code:

nohup /dir/myprog > /dir/myprog.log 2>&1 &

I merged your two threads and marked the resulting one as "unsolved".

Cheers,

OP: You've got to give a little more info, man! If you could share the code of your program, or at least to the point where it segfaults, that'd be great. In the meantime:

1. Where is the file to which your application writes "test"? if you fopen() a file that doesn't exist, the function would return a null pointer, and if you mess around with a null pointer, you're bound to get a SEGV

2. Drink Pepsi
3. Use full paths wherever possible in your program.

SIGSEGV in C is typically caused by overwriting the end of a char 'string' or an array.
A typical gotcha in re (1) is to forget about the '\0' reqd at the end of a string and write a 'normal' char over it, thus removing the EOS (end-of-string) marker that the C string fns rely on.
