Hi,
I have been trying to develop an embedded system using gentoo that can
be cross compiled. I have succeeded in building a busybox/uclibc based
system and PXE booting. I am now trying to emerge xorg-server but get
the following error:

Prior to this it has just successfully emerged xproto which has
installed the header file that this package is not picking up. Also I
can emerge xorg-server in the host environment with problems.
During its configure it spits out

Here I am trying to compile on a host i686-pc-linux-gnu for a target
i686-pc-linux-uclibc. Is this right – from my understanding(not the
best) should have --host=i686-pc-linux-glibs –target= target
i686-pc-linux-uclibc. Anyhow to continue.
My procedure for building this system involves first setting up a
chroot env with a fresh portage and then using crossdev to build a
toolchain and then emerge to build. This is the script I use to build
the chroot environment:
RBCONFDIR=${RBTHEROOT}/conf/${1}
RBMEDIADIR=${RBTHEROOT}/media
RBBUILDROOT=${RBTHEROOT}/${1}_chroot
. ${RBCONFDIR}/conf
echo "Config Dir: ${RBCONFDIR}"
echo "Making build root: ${RBBUILDROOT}"
mkdir ${RBBUILDROOT}
cd ${RBBUILDROOT}
echo "Extracting files to build root."
tar xjpf ${RBMEDIADIR}/stage3-i686-2006.0.tar.bz2
tar xjf ${RBMEDIADIR}/portage-20060703.tar.bz2 -C ${RBBUILDROOT}/usr
echo "Copying distfiles"
cp ${RBMEDIADIR}/distfiles/* ${RBBUILDROOT}/usr/portage/distfiles/
echo "Putting in place host make.conf"
cp ${RBTHEROOT}/conf/make.conf ${RBBUILDROOT}/etc/
echo "Copying DNS info"
cp -L /etc/resolv.conf ${RBBUILDROOT}/etc/resolv.conf
echo "Mounting proc filesystem"
mount -t proc none ${RBBUILDROOT}/proc
echo "Mounting dev filesystem"
mount -o bind /dev ${RBBUILDROOT}/dev
echo "Copying phase 2 build files"
mkdir ${RBBUILDROOT}/p2build
cp -r ${RBCONFDIR} ${RBBUILDROOT}/p2build/conf
cp -r ${RBTHEROOT}/build_target/* ${RBBUILDROOT}/p2build/
echo "Entering chroot"
chroot ${RBBUILDROOT} bash /p2build/build-target
The preeceeding script source this . ${RBCONFDIR}/conf:
MY_TARGET_ARCH=x86
MY_TARGET_KERNEL_ARCH=i386
MY_TARGET_CHOST=i686-pc-linux-uclibc
MY_TARGET_CFLAGS="-Os -march=pentium4 -pipe -fomit-frame-pointer"
MY_TARGET_USE="-* x86 mmx ssl theora threads tiff doc usb vcd vorbis

MY_TARGET_INPUT_DEVICES="keyboard mouse"
MY_TARGET_VIDEO_CARDS="nvidia"
This all works OK. The last line enters the chroot env and executes
the following script:
echo "Syncing source tree"
#emerge --sync
emerge xorg-server # This works so it builds ok in the host.
echo "Merging cross dev"
emerge -v crossdev
echo "Fixing overlay"
echo "PORTDIR_OVERLAY=\"/usr/local/portage\"" >> /etc/make.conf
mkdir /usr/local/portage

And this all works ok too. I can then use the built kernel and rootfs
and PXE boot it. The problem then comes when trying to emerge
xorg-server. I do the following:
ROOT="/tmp/target" \
ARCH="$MY_TARGET_ARCH" \
CHOST="$MY_TARGET_CHOST" \
CBUILD="i686-pc-linux-gnu" \
CFLAGS="$MY_TARGET_CFLAGS" \
CXXFLAGS="$MY_TARGET_CFLAGS" \
INPUT_DEVICES="$MY_TARGET_INPUT_DEVICES" \
VIDEO_CARDS="$MY_TARGET_VIDEO_CARDS" \
USE="${MY_TARGET_USE} cross -doc" \
CONFIG_PROTECT="-* ${ROOT}/etc" \
emerge $PRET -v xorg-server
and after emerging a few packages I get the error. Any help would be
greatly appreciates.
Thanks
Ryan
Wow, this is fantastic! Can I take alook?
