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:

      ./include/X11/Xauth.h:48:31: X11/Xfuncproto.h: No such file or

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



      ./configure --prefix=/usr --host=i686-pc-linux-uclibc
--mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share
--sysconfdir=/etc --localstatedir=/var/lib --prefix=/usr

      checking for C compiler default output file name... a.out
      checking whether the C compiler works... yes
      checking whether we are cross compiling... yes




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

      . /p2build/conf/conf

      echo "Creating cross toolchain: ${MY_TARGET_CHOST}"
      crossdev --binutils 2.16.1-r2 --gcc 3.4.5-r1 --libc 0.9.29 --kernel
2.6.17 -t $MY_TARGET_CHOST

      mkdir -p /tmp/target

      echo "sys-apps/baselayout-lite -*" >> /etc/portage/package.keywords

      PRET=

      echo "Creating kernel"

      mkdir /tmp/kernel

      USE="${MY_TARGET_USE} make-symlinks" \
      CONFIG_PROTECT="-* ${ROOT}/etc" \
       emerge $PRET -v busybox

      ROOT="/tmp/target" \

      VIDEO_CARDS="$MY_TARGET_VIDEO_CARDS" \
      USE="${MY_TARGET_USE} make-symlinks" \
      CONFIG_PROTECT="-* ${ROOT}/etc" \
       emerge $PRET -v busybox



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
