[crosstool-ng] problem building glibc

[Chuck Tuffli <ctuffli at gmail dot com>]

Hi -

I'm a newbie to crosstool-ng and may just be doing something stupid,  but ...

I have version 1.3.1 of ct-ng and am trying to build an ARM EABI tool
chain with:
binutils 2.19
gcc 4.1.2
glibc 2.5 + linuxthreads

but get a configuration error in glibc:
[DEBUG]    ==> Executing:
'/home/ctuffli/dev/toolroot/targets/src/glibc-2.5/configure
--prefix=/usr --build=i486-build_pc-linux-gnu
--host=arm-unknown-linux-gnueabi --without-cvs --disable-profile
--disable-debug --without-gd --disable-sanity-checks
--cache-file=config.cache
--with-headers=/home/ctuffli/x-tools/arm-unknown-linux-gnueabi/arm-unknown-linux-gnueabi/sys-root/usr/include
--with-__thread --without-tls --without-nptl --enable-shared
--without-fp --enable-add-ons=linuxthreads --enable-kernel=2.6.26'

[ERROR]    checking sysdep dirs... configure: error: The arm is not supported.

Changing line 412 of glibc.sh from
        --host=${CT_TARGET}
to
        --target=${CT_TARGET}

gets past the initial problem, but there is a subsequent failure
...

compute sizeof (long double), 77

The relevant part of config.log
...
configure:7255: checking size of long double
configure:7574: arm-unknown-linux-gnueabi-gcc   -pipe  -o conftest
-mlittle-endian    -mtune=arm926ej-s  -msoft-float   -O   conftest.c
>&5
/opt/home/ctuffli/dev/toolroot/targets/arm-unknown-linux-gnueabi/build/gcc-core-static/bin/../lib/gcc/arm-unknown-linux-gnueabi/4.1.2/../../../../arm-unknown-linux-gnueabi/bin/ld:
crt1.o: No such file: No such file or directory
collect2: ld returned 1 exit status
configure:7577: $? = 1
configure: program exited with status 1

Sure enough, I can't find crt1.o either (but did find other crt*.o
files). Was the --target change the wrong fix or is the missing file
another problem? Thanks!
