Zaurus cross-compilation in a Docker container

Target Zaurus

• Zaurus SL-C3100

Build & prepare

1. build docker container

   sh build.sh
   

Docker container image named "zxbuild" will be created. 2. extract build script, set executable permission, put it to executable path

e.g.

docker run zxbuild > zxc
chmod +x zxc
mv zxc ~/bin/

a) Compile and run hello app with gcc

1. run script to build docker container

   cd samples/hello_app
   zxc arm-linux-gcc hello.c -o hello_arm_built_by_docker
   

An executable file named "hello_arm_built_by_docker" will be created 2. copy hello_arm_built_by_docker file to SD card, then insert it to Zaurus C-3100 3. run hello_arm_built_by_docker using terminal software on Zaurus . "hello world" will be printed on terminal.

b) Compile and run hello app with make

1. run script to build docker container

   cd samples/hello_make_app/
   zxc make
   

An executable file named "hello_make" will be created 2. copy hello_make file to SD card, then insert it to Zaurus C-3100 3. run hello_make using terminal software on Zaurus . "hello world with makefile" will be printed on terminal.

Usage

• build app with gcc (prefixed with arm-linux-)

  zxc arm-linux-gcc GCCARGS...
  

• build app with make

  zxc make
  

• copy kernel image built from kernel source code

  zxc cp /root/linux/arch/arm/boot/zImage .
  

TODO

• run arm app on qemu and support zxc run
  • qemu config
• build as user
  • chpst alternative
• build more app
  • use libraries installed in zaurus to link
  • CUI app
    • openssh-server
    • cannot compile lmbench
      • freeze when compiling mhz.c
  • GUI app
    • curses app

Challenge?

• build web browser (supporting html5)
• compile and replace linux kernel
  • replace initrd?
