Just because you've built everything with --prefix=/usr/local, doesn't mean everything ended up there. In particular, watch for stuff ending up in /etc and /var, as many packages assume those locations are valid unless explicitly overridden with --sysconfdir and --localstatedir...

Re: [lfs-support] keyboard-1.15.3 errors on backspace with uk keymap

In a unicode font, that situation ought to show an inverse question mark (black-on-white for normally white-on-black text), but many fonts cannot do that. However, that doesn't explain why the backspace isn't effective. The backspace patch only changes this for a few keymaps which still gave Backspace instead of Delete - the last time I looked (some time before 1.15.3, so something might have slipped in), all of the other keymaps shipped in the package already did this.

If you don't need the bright colours, you might prefer a 512 character font. I've got a few files at http://www.linuxfromscratch.org/~ken/ in the keyboard-items and fonts directories - note that LatGrkCyr-8x16 is a 512-ish character font and ships in kbd. It comes from the sigma fonts there which are very much roll your own but do allow a 256 character font if that is what you need. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
Re: [lfs-support] Is it a must to separate Binutils and GCC into Pass 1 and Pass 2?
Hi, Thanks Chris: Thank you for your prompt reply. Unfortunately, the reason why I'm using the latest version of Binutils is deu to the current wget-list: http://www.linuxfromscratch.org/lfs/view/development/wget-list On this list, binutils-2.23.1 is used http://ftp.gnu.org/gnu/binutils/binutils-2.23.1.tar.bz2 instead of binutils-2.22 . However, on the book, it's still using binutils-2.22 http://www.linuxfromscratch.org/lfs/view/stable/chapter05/binutils-pass1.html I did notice for binutils-2.22 pass 1, there is a patch before everything starts compiling. patch -Np1 -i ../binutils-2.22-build_fix-1.patch However, I've got no idea whether this patch for binutils-2.22 is also working for binutils-2.23.1 ? Anyway, now, my question is: *is the patch a must?* Why didn't I meet any error message even without patching binutils during binutils Pass 1? Thanks again. I do need your detailed explanation. Thank you very much again. Cheers Pei On Mon, Dec 17, 2012 at 3:15 AM, Chris Staub ch...@beaker67.com wrote: On 12/17/2012 06:00 AM, JIA Pei wrote: Hi, all; Sorry to bug all of you again.

[lfs-support] Booting LFS Error Kernel Panic
Hello all,
I am having a hard time booting my LFS system, which is on a USB drive. I
installed grub on /dev/sdc (the usb relative to the host) and the bios
successfully finds GRUB. After around 2.3 seconds, the boot process hangs
after printing what I believe to be a trace call. Interestingly, one time
when I booted the trace call was short enough for me to write down the
error which I can't normally see due to the length of the trace prints.
Here is the error:
Kernel panic-not syncing: VFS: Unable to mount root fs on unknown block(0,0)
What exactly does unknown block(0,0) mean?
The problem appears to be that the kernel can't find the root file system.
How can that be a problem, if the kernel, which is ON the root file system,
was found and ran?
Here is the grub.cfg file:
# Begin /boot/grub/grub.cfg
set default=0
set timeout=5
insmod ext2
set root=(hd0,1)
menuentry GNU/Linux, Linux 3.7-lfs-SVN-20121212 {
linux /boot/vmlinuz-3.7-lfs-SVN-20121212 root=/dev/sda1 ro
}
I believe the USB is always sda because to boot I do a manual boot override
and select USB from the BIOS menu. The grub command line also confirms this.
Searching online, there were some suggestions that the kernel was compiled
without support for necessary file systems and hardware. I check my config
file for the kernel and found all the important options to be set to yes
(USB_mass_storage, ext3 filesystem, USB UHCI, USB OHCI, and several scsi
ones). There are however many USB options that are not set. Are there any
specific ones that should be set for the kernel to load the root filesystem?
Also, I've tried unsuccessfully to read more of the boot output by two
methods: increasing the resolution and scrolling back. The scroll back
buffer is set to yes in the kernel config yet shift page down and shift
page up do nothing. Also, vga=791 is deprecated and I haven't been able to
get any effect by using set vgxpayload=1024x728.
How can I read the boot print outputs without a high speed camera?
Thanks,
Alex

Re: [lfs-support] Booting LFS Error Kernel Panic
I got it to work! Turns out that the root file system changes to /dev/sdc1
after all the harddisks are found so changing the line root=/dev/sda1 to
root=/dev/sdc1 and adding a rootdelay successfully booted the system!
Now it would be nice for it to work using UUIDs so the booting can
be independent of host system.
Also, the scrollback buffer does work just not when the kernel has crashed.
I am sorry for the long kind of useless post but if anyone has anything to
add please feel free.
