Runbox, execute a program.

Hey there,

I am trying to write a runbox for linux, like in Gnome or KDE when you press Alt+F2.
The crux is, I am not sure how I can even start a program from my code base..

I tried system and execvp, however, it doesn't work, I get lots of errors like with acroread:

Code:

---

/usr/local/bin/acroread: line 204: sed: command not found
/usr/local/bin/acroread: line 229: dirname: command not found

---

If I try blender (a 3D program) it works, so it has to be the way the command is actually executed, my program is a GTK+ app, so it most likely has to be a terminal thing? Or do I need bash and I just get sh with system and execvp?

How could I change that bash is sed instead of sh, basically, I need to rewrite system, don't I?

Anyway, thanks in advance.
Bill

What do you get if you do

Code:

---

printf("path = %s\n", getenv("path"));

---

Does your sed or acroread reside in a place that you can reach with that path?

Yes, it does, i specifically get the commands from a list of files, I got from the path variable.

The path does give "/usr/local/bin/:/bin" however sed s in /bin and acroread in /usr/local/bin, could this make problems?
Well I can just start it by entering acroread into a terminal, so this shouldn't be the problem. I still suspect it to be bash, anyway I could bash as an executing shell?

Haven't got an idea. It looks like you have a shell-script as acroread, so maybe you can modify it to debug it?

It's weird, I know traced the problem to be gtk itself, if I call execvp() before the gtk_main() then it works flawlessly, when I try to call the function from within the gtk_main() (through signal binding of widgets) it doesn't work.
I even tried the glib function g_spawn_async() but it has the exact same problems.

It must be a gtk thing.

Any thoughts?
Thanks for your effort so far though, regards,
Bill

execvp searches the PATH, so if something modifies the PATH either side of calling gtk_main(), then you will observe different behaviour.

Things like 'sed' should be in standard places, so you shouldn't need the 'path' version to find them.
