Compiled XServer on Ubuntu System

This paper would try to teach you how to build the graphic system on rk3288 EVB board with Ubuntu 14.04 operate system.

Two things we need to do in this paper:

• Build our own XServer, this would help to set up the base display system.
• Replace the Mali libraries, this would help to take use of the GPU module.

Compile XServer on Ubuntu

1. Download related package

Xorg include lots of package, such as armsoc and xserver. And most of those package would need lots of others library support, like xserver would need libxcb. So first step we need to download all the packages we need.

2. Compile the xorg packages

• Compiled the marcos, create the aclocal enviroment.

• Compiled the freetype2 libraries separately, cause we need to enable the png and zlib future support for it.

compiled_freetype2(){        # Compiled zlib source code        cd zlib        ./configure --prefix="$PREFIX"        make || exit 1        make install || exit 1        cd ..       # Compiled libpng source code        cd libpng;        ./autogen.sh        ./configure  --host=arm-linux --prefix="$PREFIX"        make || exit 1        make install || exit 1        cd ..        # Compile freetype2 with zlib and png support        cd freetype2        ./autogen.sh        ./configure  --host=arm-linux --with-png=yes --with-zlib=yes --prefix=$PREFIX        make || exit 1        make install || exit 1        cd ..}case "$1" in    download)        download        ;;    compiled)        sudo stop lightdm        compiled_macros        compiled_freetype2        sudo start lightdm        ;;esac

• Compiled the left related libraries.

• Compiled the important XServer package, before we start to compiled the XServer, we need to checkout the some package branch to the special version we want. 
  

For example, if we want to build the XServer 1.12.4 

Checkout the xfont to version 
cd libXfont; 
git branch -a; 
git checkout libXfont-1.5.1 -b libXfont-1.5.1; 
cd - 

Checkout the xserver to version 
cd xserver; 
git tag | grep 1.12.4 
git checkout xorg-server-1.12.4 -b xorg-server-1.12.4 
cd - 

Checkout the armosc to rokchip branch 
cd xf86-video-armsoc; 
git branch -a; 
git checkout remotes/origin/devel/rockchip -b rockchip; 
cd -;

After declare the build version, then we could start to compiled the main XServer module.

3. Configure the XServer

For now you have build the whole XServer packages on Ubuntu system, the last things for lighting your monitor is configuring the XServer. XServer have provided the xorg.config interfaces, we just need to write the write the configure file to ensure that XServer would use Rockchip DRM driver. We have provided therk32.conf file, you just need to place them into /etc/X11/xorg.conf.d/ directly (if it does not exist, then just create it).

# Filename: rk32.conf # Path: /etc/X11/xorg.conf.d/rk32.confSection "Device"        Identifier      "Mali FBDEV"        Driver          "armsoc"        Option          "fbdev"                 "/dev/fb0"        Option          "Fimg2DExa"             "false"        Option          "DRI2"                  "true"        Option          "DRI2_PAGE_FLIP"        "false"        Option          "DRI2_WAIT_VSYNC"       "true"#       Option          "Fimg2DExaSolid"        "false"#       Option          "Fimg2DExaCopy"         "false"#       Option          "Fimg2DExaComposite"    "false"        Option          "SWcursorLCD"   "false"#       Option          "Debug"                 "true"EndSectionSection "Screen"        Identifier      "DefaultScreen"        Device          "Mali FBDEV"        DefaultDepth    24EndSection
