Hello,
I am using the latest build root release and I am trying to build a tool
chain for CS-e9302 board which has an ARM chip. I want to use the
2.6.24.7 Linux kernel (I patched it to support click modular router). I
patched that kernel and u-boot 1.3.3 with patches from
http://dev.ivanov.eu/projects/cs-e9302/ to enable the board support. I
then renamed the tar.bz2 files into file names that buildroot supports
in the menuconfig (linux-2.6.24.tar.bz2 kernel and
u-boot-2009.06.tar.bz2) and placed the files into the dl directory.
My current trouble is with uClibc 0.9.30.1. In the buildroot menuconfig
I specified that I want to build the entire Linux kernel, so as far as I
understand there is no need to use the precompiled headers option. When
I build the tool chain, it all works up to uClibc. I get the following
error "cc1: error: unrecognized command line option "-mbig-endian"". I
have included the output log down below. I would appreciate any help
with this.
Thanks,
Roman

Hello,
I have the following question regarding buildroot-2009.08. If a kernel
is selected why does the script download the 2.6.30.5 precompiled
headers anyway?
Thanks,

Because you have two selections:
1: What kernel headers to use to build uclibc/toolchain
2: What kernel (if any) to build next to rootfs

So if I want uclibc/toolchain to run a 2.6.24.7 kernel on the ARM
device, I will have to manually edit the Config which is used by
menuconfig to allow 2.6.24.7 to be used for precompiled headers?
Thanks

No, not necessarily. The kernel headers for your toolchain doesn't have
to correspond to the kernel version you are using (E.G. you don't have
to install a new version of libc every time you update your kernel on
your PC either - Or the other way around.

I have untared a fresh copy of build root 2009.8. When I run make for
the first time, there is an error regarding the absence of
toolchain_build_arm/uClibc.config.arm and the process stops (see error
log below). If I do 'touch toolchain_build_arm/uClibc.config.arm' then
run make again, there is a series of questions which pertain to which
configs should be used.
I am using my own target/device. But that mainly defines the U-BOOT
config variable (cs-e9302), and I don't have any uClibc configuration
files in that directory. I am just curious if this is a bug or if I am
doing something wrong.

I am starting to suspect that for whatever reason uClibc is not using
the cross compiler and is instead using the host compiler. I am just
curious on the typical debugging procedure for this. Thanks.

if the paths in the tarballs don't match the name of the tarball and the
version in the BR config then this will not work.
I've sent a patch to the list a couple of days ago where you can set the
kernel version manually to ease this particular thing, fyi.
This and a handful of other patches are still not applied yet, though.

Even if you build on an arm box this is incorrect.
I suggest you start from a fresh BR config:
you at box:buildroot $ rm -f .config ; make menuconfig

I changed the path names by hand so that linux-2.6.24.7.tar.bz2 is
linux-2.6.24.tar.bz2 and is extracted into a 2.6.24 directory.

I specified that I have an ARM processor with EABI. For libc, I used
the default 0.9.30.1. For the actual device, I had to make my own entry
in device. I copied the following into the Makefile.in
UCLIBC_CONFIG_FILE=$(TOOL_BUILD_DIR)/uClibc.config.$(ARCH) from one of
the device directories. Once, I commented that out, the problem
disappeared.
