  1. !/bin/bash
  2. Script to fetch and build X.org (incl. XCB and pixman), DRI, Mesa and
  3. xkeyboard-config from CVS and GIT, and save full git snapshots of their
  4. source and installation.
  5. Default action:
  6. - Create/update a git repository for each module, under $HOME/3d-pit.
  7. - Install all modules, under $HOME/3d-pit/install
  8. - Make $HOME/3d-pit/install a git repository to track the installed binaries
  9. - Make $HOME/3d-pit a git super-repository which tracks all of the above
  10. using the submodule mechanism of git >= 1.5.3.
  11. Each of these can be disabled via command line (see the code table below).

  3. whatever you're testing (or are required for the build), sorted by
  4. build order (see util/modular/build.sh for dependencies).

  1. Directory hashes for change detection

}

  1. Fetching and building libDRM and DRM kernel drivers

fetch_drm() {

 fetch_from_git "$PIT" "$DRM_GIT" drm

}

build_libdrm() {

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

}

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

build_mesa() { (

   fetch_from_git $PIT/xorg "$XORG_GIT" "$D" "${D#xorg/}"
 done

}

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

 done
 run sudo sh -c "chown -v root $DEST/bin/Xorg; \
                 chmod -v 4750 $DEST/bin/Xorg"

}

  1. Fetching and building xkeyboard-config

fetch_xkeyboard_config() {

 echo "########### Fetching xkeyboard-config ###########"
 XKBC_CVS=":pserver:anoncvs@cvs.freedesktop.org:2401/cvs/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

) }

  1. 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

 ! $GIT_CLEAN  || run git clean -x -d
 ! $MAKE_CLEAN || run make clean
 run make
 run make install PREFIX="$DEST" MANDIR="$DEST/share/man"
 #run cp -v synaptics_drv.so $DEST/lib/xorg/modules/input/

) }

  1. Creating a script which sets env vars

create_xsetenv() {

 echo "Creating $DEST/bin/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 }

  1. Actual fetching and building:

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

  1. Saving install and super state to git commits:

if $BUILD; then

 echo "########### Record installation dir commit ###########"
 cd $DEST
 if [ ! -d .git ]; then
   run git init
   echo '/var/log' > .gitignore
   run git add .gitignore
   run git commit -a -m "initial"
 fi
 run git add .
 if ! nothing_to_commit; then
   run git commit -a -m "`date +'Installed at %Y-%m-%d %H:%M:%S'`"
   run git gc
 fi
 add_to_supermodule "$DEST_SUBDIR"

fi

if $SUPERMODULE; then

 echo "########### Record supermodule commit ###########"
 cd $PIT
 nothing_to_commit || run git commit -m "`date +'Snapshot at %Y-%m-%d %H:%M:%S'` `$FETCH && echo fetch` `$BUILD && echo build`"

fi

echo echo "Done." ! $FETCH || echo "Run '. $DEST/bin/xsetenv' to point env vars to this installation."
