I built buildroot from svn for i486 and try to run it in qemu.
~/qemu/bin/qemu -hda binaries/uclibc/rootfs.i686.ext2 -kernel
project_build_i686/uclibc/linux-2.6.24.3/arch/i386/boot/bzImage -append
root=/dev/hda
After booting the kernel, it complains about not finding /etc/init.d/rcS
- where did it go? It used to be there in earlier times.
Then I can activate a shell by hitting Enter.
The shell works fine, but whenever I try to enter a command which
contains a "-", I get an error message or the shell blocks.
e.g.
/ # ls -l
-> terminal blocks
somtimes I can use <ctrl>-c to escape, sometimes I have to quit qemu.
Any suggestions, why this can happen?
Regards,
Christof

Hi Christof,
I have also seen some very weird stuff happen with the latest buildroot
running in a qemu virtual machine. Things like mount requiring -v to work
properly and command line parameters not being passed and other really
strange stuff. I wish someone with a little more experience would try
building for x86 and see how it goes. I had nothing but trouble and finally
gave up. Everything works pretty well on my AVR32 target, so it imust be
something specific to x86 or maybe qemu causing the problems.

The problem is the avr32 patch against GCC.
It took me the past 3 days with Jacmet to track it down.
900-avr32-atmel.1.3.2.patch <= THAT patch.
I'm still investigating how to fix it.

As the patches after it will more than likely fail ... remove every
patch 900 and above and it works perfectly no problem.

Wow. That stinks. I'll forward this message to the Atmel guys and see if
they have any idea what to do to maybe fix this.

The AVR32 patches for GCC (and Binutils) are vendor specific so I would
not recommend applying them to other architectures.
That is also one of the reasons it is better for the time being to
separate out the AVR32 specific stuff from Buildroot in a separate
branch.
When time comes, and stuff is properly merged, there should be very
little difference between upstream and the AVR32 branch.
