}

}

2. Fetching and building libDRM and DRM kernel drivers

fetch_drm() {

 echo "########### Fetch DRM ###########"
 DRM_GIT=git://anongit.freedesktop.org/git/mesa
 fetch_from_git "$PIT" "$DRM_GIT" drm

}

build_libdrm() {

 echo "########### Build libdrm ###########"
 run cd $PIT/drm
 if dir_hash_changed; then
   run ./autogen.sh
   CFLAGS="$FLAGS" run ./configure --prefix=$DEST --quiet
   save_dir_hash
 fi
 ! $MAKE_CLEAN || run make clean
 run make
 save_dir_hash
 run make install
 save_dir_hash

}

build_drm_modules() {

 echo "########### Build DRM kernel modules ###########"
 run cd $PIT/drm/linux-core
 ! $MAKE_CLEAN || run make clean
 run make DRM_MODULES="radeon"
 run sudo sh -c \
   'rm -fv /lib/modules/`uname -r`/kernel/drivers/char/drm/*.ko; \
    cp -v *.ko /lib/modules/`uname -r`/extra/; \
    /sbin/depmod -a'

}

2. Fetching Mesa

fetch_mesa() {

 echo "########### Fetching Mesa ###########"
 MESA_GIT=git://anongit.freedesktop.org/git/mesa
 run mkdir -p $PIT
 run cd $PIT
 fetch_from_git "$PIT" "$MESA_GIT" mesa

}

2. Building Mesa (do this after installing base X.org libraries

build_mesa() { (

 echo "########### Building Mesa ###########"
 # This uses both old-style and new-style vars, to support older Mesa snapshots.
 run cd $PIT/mesa
 export DRM_SOURCE_PATH=$PIT/drm
 export PKG_CONFIG_PATH="$DEST/lib/pkgconfig:$PKG_CONFIG_PATH"
 export DRM_SOURCE_PATH="$PIT/drm"
 export DESTDIR=$DEST  INSTALL_DIR=$DEST
 export DRI_DRIVER_INSTALL_DIR=$DEST/lib/dri
 export DRI_DIRS='r300 r200 r128 radeon'
 export OPT_FLAGS="$FLAGS"
 export PATH="$DEST/bin:$PATH"
 run mkdir -p $DRI_DRIVER_INSTALL_DIR
 ! $MAKE_CLEAN || run make clean
 if [ -e configs/current ]; then
   run make -e
 else
   run make -e linux-dri-x86
 fi
 run make -e install
 run cp -v lib/*_dri.so $DRI_DRIVER_INSTALL_DIR

) }

2. X.org setup
3. This is a list of modules that are in flux and likely to be related to
4. whatever you're testing (or are required for the build), sorted by
5. build order (see util/modular/build.sh for dependencies).
6. Check CVS and the above URLs for other modules.
7. For exhaustive list, see
8. get -qO - http://gitweb.freedesktop.org/ \
9. | perl -ne 'print "$1\n" if m!<a href="/\?p=([^;]+);a=summary">!' \
10. | egrep '^xcb/|^xorg/'

XORG_DIRS=(

 xorg/util/macros
 xorg/proto/{bigreqs,composite,fixes,damage,gl,input,kb,pm,randr,resource,xext,xcmisc}proto

)

2. Fetching X.org

fetch_xorg() {

 echo "########### Fetching (selected) X.org modules ###########"
 XORG_GIT=git://anongit.freedesktop.org/git
 run mkdir -p $PIT/xorg
 for D in "${XORG_DIRS[@]}"; do
   if $D == xcb/*  && ! $USE_XCB; then continue; fi
   fetch_from_git $PIT/xorg "$XORG_GIT" "$D" "${D#xorg/}"
 done

}

2. Building and installing X.org
3. (On repeated runs we avoid rerunning autotools if nothing changed.)

build_x_module() { (

 D="${1#xorg/}"
 echo "########### Building xorg/$D ###########"
 export PATH="$DEST/bin:$PATH"
 export PKG_CONFIG_PATH="$DEST/lib/pkgconfig:$PKG_CONFIG_PATH"
 export ACLOCAL="${AC_LOCAL:-aclocal} -I $DEST/share/aclocal"
 export LD_LIBRARY_PATH="$DEST/lib:$LD_LIBRARY_PATH"
 if [ $D == "xserver" ]; then
   CONF_OPT="--with-mesa-source=$PIT/mesa --enable-xorg --disable-dmx --disable-xvfb --disable-xnest --disable-xprint"
 elif [ $D == "lib/libX11" ] && ! $USE_XCB; then
   CONF_OPT="--with-xcb=no"
 else
   CONF_OPT=
 fi
 run cd $PIT/xorg/$D
 if dir_hash_changed; then
   CFLAGS="$FLAGS" run sh autogen.sh --prefix=$DEST --quiet --cache-file=$PIT/xorg/autoconf.cache $CONF_OPT
   save_dir_hash
 fi
 ! $MAKE_CLEAN || run make clean
 run make
 save_dir_hash
 run make install
 save_dir_hash

) }

build_xorg() {

 run cd $PIT/xorg
 run mkdir -p $DEST/share/aclocal
 run mkdir -p $DEST/var/log
 for D in "${XORG_DIRS[@]}"; do
   if $D == xcb/*  && ! $USE_XCB; then continue; fi
   build_x_module $D || return 1
 done
 run sudo sh -c "chown -v root $DEST/bin/Xorg; \
                 chmod -v 4750 $DEST/bin/Xorg"

}

2. Fetching and building xkeyboard-config

fetch_xkeyboard_config() {

 echo "########### Fetching xkeyboard-config ###########"
 XKBC_CVS=:pserver:anoncvs@cvs.freedesktop.org:2401/cvs/xkeyboard-config
 run cd $PIT
 grep -qF $XKBC_CVS ~/.cvspass || run cvs -d $XKBC_CVS login
 [ -d xkeyboard-config ] || run cvs -z3 -d $XKBC_CVS co xkeyboard-config
 run cd $PIT/xkeyboard-config
 run cvs -z3 update -ACPd

}

build_xkeyboard_config() { (

 echo "########### Building xkeyboard-config ###########"
 run cd $PIT/xkeyboard-config
 run ./autogen.sh
 export PKG_CONFIG_PATH="$DEST/lib/pkgconfig:$PKG_CONFIG_PATH"
 export PATH="$DEST/bin:$PATH"
 CFLAGS="$FLAGS" run ./configure --quiet --prefix=$DEST \
   --with-xkb-base=$DEST/share/X11/xkb --with-xkb-rules-symlink=xorg
 run make
 # "make install" replaces share/X11/xkb/compiled.tmp with a junk symlink, so override it:
 mv $DEST/share/X11/xkb/compiled $DEST/share/X11/xkb/compiled.tmp
 run make install
 rm -f $DEST/share/X11/xkb/compiled
 mv $DEST/share/X11/xkb/compiled.tmp $DEST/share/X11/xkb/compiled

) }

2. Fetching and building the synaptics driver

fetch_synaptics() {

 echo "########### Fetch synaptics ###########"
 SYN_GIT=http://web.telia.com/~u89404340/touchpad/synaptics/.git
 fetch_from_git "$PIT" "$SYN_GIT"  synaptics

}

build_synaptics() { (

 echo "########### Build synaptics ###########"
 run cd $PIT/synaptics
 export PKG_CONFIG_PATH="$DEST/lib/pkgconfig:$PKG_CONFIG_PATH"
 export PATH="$DEST/bin:$PATH"
 ! $MAKE_CLEAN || run make clean
 run make
 run cp -v synaptics_drv.so $DEST/lib/xorg/modules/input/

) }

2. Creating a script which sets env vars

create_xsetenv() {

 cat <<EOF > $DEST/bin/xsetenv || die "Can't create $DEST/bin/xsetenv"

export PATH="$DEST/bin:$PATH" export LD_LIBRARY_PATH="$DEST/lib:$LD_LIBRARY_PATH" export LIBGL_DRIVERS_PATH=$DEST/lib/dri EOF

 echo -e "\nRun '. $DEST/bin/xsetenv' to point env vars to this installation."

}

2. Do it:

FETCH=true BUILD=true

if $FETCH; then

  fetch_drm
  fetch_mesa
  fetch_xorg
  fetch_xkeyboard_config
  fetch_synaptics

fi if $BUILD; then

  build_libdrm
  build_drm_modules
  build_xorg
  build_mesa
  build_xkeyboard_config
  build_synaptics
  create_xsetenv

fi

echo 'Done.'
