Hello friends

After some months i need to rebuild my arm-softfloat-linux-gnu toolchain.

Every --l --g --b --k version combination i tryed fails.
I can't find the table of working combinations, which was accesible from
embedded gentoo handbook (imho).

I did the complex cleaning of /etc/portage, but maybe there is still some
garbage.
Please recommend me, what to check up.

Thank You

Is the arm-version needed? armv6, armv7, etc?

I just built arm-softfloat-eabi without problems, though that's
pretty different.

The chip has core arm920t, where i get info about its name in current
crossdev?

I have functional system built with toolchain generated before two years, now
i must appned some new packeges and do upgrade, but my toolchain stops
working, i need functional arm-softfloat-linux-gnu toolchain, not eabi for
binary compatibility. I need to send binary package via slow curious line to
the system and it must run.

Three days of trying and still nothing, i'm stuck in big piece of shit.
I have somewhere backup of old toolchain, on former colegue's notebook, but
...

If it's an 920t then most likely you will want a chost such as
armv4tl-softfloat-linux-gnu(eabi)

Try not to get discouraged. If it's not working for you. Take a break,
and return at a later time when you feel less stressed.

Here are some known working versions.

wizdev local # qlist -I armv4tl -v
cross-armv4tl-softfloat-linux-gnueabi/binutils-2.19.1-r1
cross-armv4tl-softfloat-linux-gnueabi/gcc-4.2.4
cross-armv4tl-softfloat-linux-gnueabi/gcc-4.4.2
cross-armv4tl-softfloat-linux-gnueabi/glibc-2.9_p20081201-r2
cross-armv4tl-softfloat-linux-gnueabi/linux-headers-2.6.30-r1

I am a little bit confused, why i foundn't it in the handbook.

This is a good idea :-)

Thank You very much.

Tryed these versions, both gcc 4.2.4 and 4.4.2, both gnu and gnueabi and
everything failed :-(
Don't have any clue what is wrong with my system.

Hey!

Well, your problem is described easily once you read
cross-armv4tl-softfloat-linux-gnueabi-glibc-headers.log::

checking for /usr/lib/gcc/i686-pc-linux-gnu/4.3.4/../../../../i686-pc-linux-gnu/bin/as...

and checking the glibc-2.9_p20081201-r2 's configure script:

4530 echo $ECHO_N "checking version of $AS... $ECHO_C" >&6; }
4531 ac_prog_version=`$AS --version 2>&1 | sed -n 's/^.*GNU
assembler.* ([0-9]*.[0-9.]*).*$/1/p'`
4532 case $ac_prog_version in
4533 ') ac_prog_version="v. ?.??, bad"; ac_verc_fail=yes;;
4534 2.1[3-9]*)
4535 ac_prog_version="$ac_prog_version, ok"; ac_verc_fail=no;;
4536 *) ac_prog_version="$ac_prog_version, bad"; ac_verc_fail=yes;;
4537
4538 esac

In the above lines, you see that the binutils-2.20.1.20100303
of your host is too new for the glibc version, which requires
version 2.1*. :-) If you require this glibc version one would
need to replace the check in line 4534 with

2.1[3-9]*|2.2[0-9]*)

and test with this setting. Alternatively you could try with
>=glibc-2.11.1 which has a check for newer binutils.

Have fun!

Sven

This helped!!!!!

Thank You
