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
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
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?
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.
