binutils - Pass 2 configuration issue

Hi All,

I have a user level understanding of linux and have done some application programming using gcc.

I have just started out with LFS7.1 and it has been a smooth ride until 5.8 (Adjusting the toolchain).

The problem i am facing is with 5.9 :

While running the script: "binutils-2.22/configure", it failed with config.log showing three errors:

*********************************************************************
configure:4009: x86_64-lfs-linux-gnu-gcc -B/tools/lib/ -V >&5
x86_64-lfs-linux-gnu-gcc: error: unrecognized option '-V'

configure:4143: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.
***********************************************************************

Since man x86_64-lfs-linux-gnu-gcc didn't have -V  and -qversion options , i modified binutils-2.22/configure as follows:

#Original source:
for ac_option in --version -v -V -qversion; do

#Modified source
for ac_option in --version -v; do

With this change , i dont get the first two errors but the last error (not finding ./a.out) still exists.
*********************************************************************
gcc version 4.6.2 (GCC)
configure:4020: $? = 0
configure:4040: checking for C compiler default output file name

configure:4143: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.
*********************************************************************
 
My questions:
1) How come invalid options such as -V and -qversion have ended up in the configure script ? Is there something that i have missed here ?
2) How come the same scripts worked during the first pass ?
3) How do i solve the last problem ? (./a.out)


I would be grateful for any help/ advise.

Regards

lfs7.1 cannot boot

Hi, all:
I finished all work of the LFS 7.1 book except the error when booting my LFS.

Firstly, I states my LFS 7.1.
I use VMware installed Ubuntu 10.04 on a virtual SCSI disk of 20G. Before beginning, I add another 8G virtual SCSI disk to VM and mount it in the Ubuntu manually. So the first disk with Ubuntu displays sda in /dev/ and the second which is mounted newly displays sdb in /dev/. Following the book I install LFS 7.1 on the sdb1 which is formatted with ext3 on the sdb and given only one partition. All pass with no error.
According to my disk in chapter 8.4.3 I run cmd as grub-install /dev/sdb and in chapter 8.4.4 I save grub.cfg as follows.

# Begin /boot/grub/grub.cfg
set default=0
set timeout=5

insmod ext2
set root=(hd1,1)

menuentry "GNU/Linux, Linux 3.2.6-lfs-7.1" {
        linux   /boot/vmlinuz-3.2.6-lfs-7.1 root=/dev/sdb1 ro
}

After a few works such as logout and unmount, I reboot the computer. But it starts up using Ubuntu again only appearing error checking of a moment.

Then I change the cmd in chapter 8.4.3 to grub-install /dev/sda and keep grub.cfg the same and reboot again. The computer gives errors as follows and stop starting up.

md: Autodetecting RAID arrays.
md: Scanned 0 and added 0 devices.
md: Autorun ...
md: ... autorun DONE.
Root-NFS: on NFS server address
VFS: Unable to mount root fs via NFS. trying floppy.
VFS: cannot open root device "sdb1" or unknown-block(2.0)
Please append a correct "root=" boot option; here are the available partitions:
0b00    1048575   sr0 driver: sr
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2.0)
Pid: 1. comm: swapper/0 Not tained 3.2.6 #1
Call trace:
...mount_block_root+0x141/0x1c9...mount_root...kernel_init...

I search this problem from lfs mail list and google, which says that compiling kernel needs some SCSI driver or changing hda to sda in the grub.cfg and etc. . I compile the kernel again with more drivers like SCSI. When I reboot again, it is the same.

Could anybody help me? Thanks in advance.

Omar

handle power button in LFS

In order to use "power button" to shutdown or suspend my lfs.
I enabled the depreciate  /proc/acpi/event in kernel,
and install acpid to handle the button event.
It works well.

But is there any clear way to do that, such as by inittab or udev
or kernel callout userspace script ( /proc/sys/kernel/poweroff_cmd has
somethings )

I've looked into blfs, there's a lot more packages need to be
installed to enable this.(I'm not a X user,for now.)

Thanks.

In my machine, LFS-7.1 compiled good with -j2 switch except automake in section 6. however, so far!

That surprises me. Runnning tests in parallel may be flaky, but the
actual compilation step should be fine. Every package in the book built
fine with -j6, last time I tried (on hardware capable of it).

LFS-7.1: 6.37. Automake-1.11.3 (TEST FAILURE)!

Hi,

'make -j2 check' on 'LFS-7.1: 6.37. Automake-1.11.3 (http://www.linuxfromscratch.org/lfs/view/stable/chapter06/automake.html)' informs me for one failure with following red message :(

=====================================
1 of 842 tests failed
(96 tests were not run)
See tests/test-suite.log
Please report to bug-automake <at> gnu.org
=====================================
make[3]: *** [test-suite.log] Error 1
make[3]: Leaving directory `/sources/automake-1.11.3/tests'
make[2]: *** [check-TESTS] Error 2
make[2]: Leaving directory `/sources/automake-1.11.3/tests'
make[1]: *** [check-am] Error 2
make[1]: Leaving directory `/sources/automake-1.11.3/tests'
make: *** [check-recursive] Error 1

I also reviewed 'tests/test-suite.log' for word 'Error' and found following rows which are maybe related:

+ make
Making all in src
make[1]: Entering directory `/sources/automake-1.11.3/tests/depcomp10.dir/build/src'

Is this failure expected or is a fatal error (and the process could not be continued before resolving it)?! Or do you think that eliminating '-j2' switch will resolve it (I should know before trying because it's test take 31 minutes to complete(i.e. 1 hour without -j2!))?

Thanks in advance!

LFS-71.: Solution for automation of 'tar X', 'cd X' ... 'cd ..', 'rm -R X'.

Hi there,

As for each package you should decompress the package, enter decompressed folder, compile&install and finally remove decompressed folder, and also while you do not learn any new thing by doing these each time, so I would like to share my automation solution which does these just by getting a partial name of the package:

To create the main .sh file, issue following commands while you're logged in by chroot (section 6 of LFS-7.1) and also you're in '$LFS/sources' directory:

cat > t.sh << EOF
if [ "$1" == "" ]; then
    echo 'USAGE: t.bash [name]'
    return
fi
FNAME=$(ls $1* | grep tar.xz)
if [ "$FNAME" == "" ]; then
    FNAME=$(ls $1* | grep tar.gz)
    if [ "$FNAME" == "" ]; then
        FNAME=$(ls $1* | grep tar.bz2)
        if [ "$FNAME" == "" ]; then
            echo 'match not found!'
            return
        else
            TARPARAM='-jxf'
            EXT='.tar.bz2'
        fi
    else
        TARPARAM='-zxf'
        EXT='.tar.gz'
    fi
else
    TARPARAM='-Jxf'
    EXT='.tar.xz'
fi
DIR=$(echo $FNAME | sed "s/$EXT//g")
echo `rm -fR $DIR`
echo `ls $1*`
echo `tar $TARPARAM $FNAME`
rm -vfR ut.sh
echo -e 'cd ..\necho `rm -fR '$DIR'`\necho `ls '$1'*`\nrm -vfR ut.sh' >> ut.sh
chmod 777 ut.sh
cd $DIR
EOF
chmod 777 t.sh

Now, to use automation, act like following:
  1. Issue following command to decompress and enter to decompressed folder by just specifying package partial name:
  • source ./t.sh [package-partial-name] e.g. source ./t.sh autoco for autoconf-2.68 package.
  • NOTE: package-partial-name should be long enough to distinct the package from others e.g. source ./t.sh bi is not suitable at all because can not distinct between binutils and bison!
  • Do the book's instructions to configure, compile, test and install the package.
  • Issue following command to undo the above instruction #1.
    • source ../ut.sh.

    Sicerely Yours,
    Yasser.

    6.2.3. Mounting Virtual Kernel File Systems question

    Hi All,
I've recently updated my main workstation to LFS 7.1 (From LFS 6.7), and
noticed one of my auto build scripts is now failing.
I've tracked it down to the following command.
mount -vt tmpfs shm $LFS/dev/shm
It seems to me that this command is mounting onto /run/shm rather than
/mnt/lfs/dev/shm due to /mnt/lfs/dev/shm being a symlink to /run/shm.
Further more, when entering chroot environment, /dev/shm is now pointing
to a no existent /run/shm.
Am I'm doing something wrong or is this a bug?
Thanks,
Wayne.

    Do you know why 2 CPUs act like a mirror in GCC test?

    Hi,

    Sorry if it's off-topic; do you know why 2 CPUs act like a mirror while I'm running "make -k check" for testing GCC-4.6.2 (6.17's section of LFS-7.1)? it's not a problem but just I would like to know; I've attached an image which shows this while I was not running anything except GCC testing and Debian's System Monitor.

    I think it'll be an interesting reason that causes 2 CPU's mirror action during all test process!

    Thanks!

    Problems starting the final LFS system

    Hello,

After complete the LFS book, when I restart the computer I get a few  
errors messages and the computer stuck after this:

     /lib/lsb/init-functions: line 590: /run/var/bootlog: No such file or

The LFS version is 7.1 and is running on VirtualBox with PAE/NX and VT-x,  
the processor is a dual-core E5300 and the virtual machine have 512MiB of  
RAM. Could be this a problem? LFS can be compiled on VirtualBox?

Thanks very much,
Lázaro
