I am just working on a QT GUI program which is the only program executed on a minimal system build by buildroot for a RaspberryPi Compute Module. But I think this should not matter.
My problem is that in my code I am executing shell scripts with QProcess,
but when I run my program out of inittab
I can't get any exit codes of the shell scripts. I know that they have been executed because I tried some mv
and mkdir
, and the folders existed afterwards. But they script does not return me the exit code.
"
When I run my program out of init.d
everything works perfectly. Only problem I have with this solution, is that I don't have root permissions, which I need for example for reboot
command.
"
Edit
This above was wrong. I mentioned that i switched to inittab at the same time when i updated buildroot. So init.d does not work now either. So must be a problem with buildroot. Does anyone know how this can happen?
*Edit
Here is what my inittab
looks like:
# Startup the system
::sysinit:/bin/mount -t proc proc /proc
::sysinit:/bin/mount -o remount,rw /
::sysinit:/bin/mkdir -p /dev/pts
::sysinit:/bin/mkdir -p /dev/shm
::sysinit:/bin/mount -a
::sysinit:/bin/hostname -F /etc/hostname
# now run any rc scripts
::sysinit:/etc/init.d/rcS
# console tty1 autologin as root
#::respawn:/bin/login root tty1 </dev/tty1 >/dev/tty1 2>&1
#starting ziesel
:12345:respawn:/usr/bin/ziesel
# Put a getty on the serial port
#tty1::respawn:/sbin/getty -L tty1 0 vt100 # GENERIC_SERIAL
# Stuff to do for the 3-finger salute
#::ctrlaltdel:/sbin/reboot
# Stuff to do before rebooting
::shutdown:/etc/init.d/rcK
::shutdown:/sbin/swapoff -a
::shutdown:/bin/umount -a -r
So as you can see I only start my ziesel program here, without any console. But when I don't comment out the line above, where I auto login as root, it does not work either.
I would be very very grateful for any suggestions.
