[Buildroot] rebuild problem, fakeroot complaining.

[Richard Rondu]

Hi,

I've been using buildroot-2009.05 to create the toolchain and minimal
environment for my arm9 development board sky2440-v2.
It works well, but only the first time. Once i try to rebuild an image
with the modification i just made in
project_build_arm/uclibc/root/etc/inittab the build fail with the
following error message:

<lainwir3d@d830:~/development/sky2440-v2/buildroot-2009.05>

If i reboot then i can build again one time but the next fails.
Rebooting every build is kind of annoying.

Can someone help me please or point me in the right direction?

Thanks for the help,

I've never seen this, but from the error message, looks like the linux
kernel on your host computer lacks SYSV IPC support. Try enabling it,
should fix the problem. You would have to recompile your kernel, or do
some distro wizardry to get the right precompiled kernel package.

That's also what I would have said, but Richard reports in its original
e-mail: "If i reboot then i can build again one time but the next
fails.".

So it looks like fakeroot works once, and then the next times fails.
Maybe fakeroot only uses SysV IPC in some cases, but that seems odd.

I've also never seen such a report.

Sincerly,

Thomas
