hi again,

El Mon, May 12, 2008 at 05:00:32PM +0200 Matthias Kaehlcke ha dit:

> ARM toolchains with glibc 2.7 don't build with crosstool-ng, due to an

> patch fixes this problem

in my first attempt i build an EABI toolchain. later i tried to build
the same toolchain with OABI but it failed with an assembler
error. googling i found the following solution: 

http://sources.gentoo.org/viewcvs.py/*checkout*/gentoo/src/patchsets/glibc/2.7/6225_all_glibc-2.7-cargs6.patch

below is a new patch that fixes the assembler error and the include
problem of the initial patch

for if someone is interested i attached the configuration files for
building crosstool-ng with glibc 2.7 (EABI and OABI) that work for me
in combination with these patches
