These are the instructions to build a version of Orbiter for the Nokia 770 internet platform. Nokia 770 has an ARM family processor, therefore you will need to cross-compile if your build machine is an Intel.

Requirements

You will need: 

 scratchbox-core_0.9.8.5_i386.deb                              
 scratchbox-devkit-debian_0.9.8.5_i386.deb                     
 scratchbox-doctools_0.9.8.5_i386.deb                          
 scratchbox-libs_0.9.8.5_i386.deb                              
 scratchbox-toolchain-arm-glibc_0.9.8.5_i386.deb               
 scratchbox-toolchain-i686-glibc_0.9.8.5_i386.deb

Preparing the Nokia tablet

  1. Make sure it is connected to the network - check the Connection manager for a WiFi connection
  2. Open an X terminal on the tablet; make a directory in your home dir to hold the Orbiter binaries, say /home/user/orbiter
  3. You'll need a way to transfer files from the build machine to the tablet. Either have an HTTP server somewhere on your network, or install OpenSSH on the tablet. If you install OpenSSH, remember to also start it, by doing /etc/init.d/ssh start. To get a root prompt, use sudo gainroot.

Preparing the build machine

  1. Install Scratchbox debs on the build machine
  2. Add yourself as a Scratchbox user: /scratchbox/sbin/sbox_adduser username
  3. Check out a fresh working copy of Pluto from http://svn.plutohome.com/pluto/trunk/src/ into /scratchbox/users/username/pluto/trunk/src (username is assumed to be your user name on the build machine)
  4. Copy or symlink the Maemo SDK into /scratchbox/packages
  5. Log in to Scratchbox by typing scratchbox
  6. Configure Scratchbox cross-compile target:
> sbox-config -ct Nokia770

Available compilers:
       0) arm-linux-gcc-3.3_3.3.4-glibc-2.3.2.ds1
       1) host-gcc
       2) i686-linux-gcc-3.3_3.3.4-glibc-2.3.2.ds1

Enter compiler number: 0

Available CPU-transparency methods:
       sbrsh
       qemu-arm
       qemu-ppc

Enter method name (qemu-arm): qemu-arm

Available devkits:
        debian

Enter list of devkit names (none): debian
  1. Select the new cross-compile target: sbox-config -st Nokia770
  2. Unpack the Maemo rootstrap: sbox-config -er /scratchbox/packages/Maemo_Dev_Platform_RS_v1.1_arm.tgz
  3. sbox-config -cc
  4. sbox-config -cf
  5. Update the package list inside Scratchbox by typing apt-get update
  6. Install the following build-time dependencies (with apt-get install)
    • libmysqlclient12-dev
    • libid3-dev
    • xlibmesa-gl-dev
  7. Edit the following Makefiles as follows:
    • /pluto/trunk/src/SerializeClass/Makefile: append " -DMAEMO_NOKIA770" to CXXFLAGS on line 4
    • /pluto/trunk/src/PlutoUtils/Makefile: append " -DMAEMO_NOKIA770" to CXXFLAGS on line 4
    • /pluto/trunk/src/DCE/Makefile: append " -DMAEMO_NOKIA770" to CXXFLAGS on line 4
    • /pluto/trunk/src/Orbiter/Makefile: append " -DMAEMO_NOKIA770" to CPPFLAGS on line 74

Building Orbiter

  1. While inside Scratchbox, go into /pluto/trunk/src/SerializeClass and type make
  2. Go into /pluto/trunk/src/PlutoUtils and type make
  3. Go into /pluto/trunk/src/DCE and type make
  4. Go into /pluto/trunk/src/Orbiter and type make bin
  5. After a while, the following files will result in /pluto/trunk/src
    • lib/libDCECommon.so
    • lib/libSerializeClass.so
    • lib/libPlutoUtils.so
    • bin/Orbiter
  6. Copy these files over to the tablet, in /home/user/orbiter

Running Orbiter

In an X terminal On the tablet itself (NOT via ssh) do this: 

cd /home/user/orbiter
export LD_LIBRARY_PATH=.
./Orbiter -r xxx.xxx.xxx.xxx -d yy -l orbiter.log

where xxx.xxx.xxx.xxx is the IP address of the DCE Router, and yy is the device number assigned to your new Orbiter.

If it complains about missing .so files, copy them over from your Scratchbox on the build machine into /home/user/orbiter on the tablet.
