[Buildroot] buildroot with ELDK 4.1

[Buildroot] buildroot with ELDK 4.1

[Wenwei Zha]

Hi,

I just started to learn using buildroot to build a root file system. I
would like to use ELDK 4.1 as my toolchain but has some problem.

I might have some improper settings, but "make saveconfig" gives me no
error and "make" (without busybox) seems to be fine.

However, when I enable busybox installation, I can't go through
"make". I encounter error at this command:

/usr/bin/make -j1 CC=/home/wenwei/ELDK/usr/bin/ppc_4xx-gcc
CROSS_COMPILE="/home/wenwei/ELDK/usr/bin/ppc_4xx-"
CROSS="/home/wenwei/ELDK/usr/bin/ppc_4xx-"
PREFIX="/home/wenwei/temp/temp/buildroot-2009.05/project_build_powerpc/linux_26_ml410/root"
ARCH=powerpc EXTRA_CFLAGS="-Os -pipe -Os  --sysroot
/home/wenwei/temp/temp/buildroot-2009.05/build_powerpc/staging_dir/"
-C /home/wenwei/temp/temp/buildroot-2009.05/project_build_powerpc/linux_26_ml410/busybox-1.14.1

Why I get this error? Is there some issue with ELDK? It seems to me
that buildroot comes with uClib but ELDK should work ....

Anybody went through the same error? Please give some help.

best regards

That won't work - Your toolchain has to support sysroot (gcc 4.2 or
newer). As far as I can see on google, ELDK 4.1 used 4.0.
