This section gives a step by step example on how LXRT could be used with mca2.

Download and Patching

  • Create a directory of your choice
  [~]$ mkdir /tmp/rtai-test
  [~]$ cd /tmp/rtai-test
  [/tmp/rtai-test]$ tar xzf mca2.4-beta.tgz 
  [/tmp/rtai-test]$ tar xjf linux-2.4.29.tar.bz2  
  [/tmp/rtai-test]$ tar xjf rtai-3.2.tar.bz2  
  [/tmp/rtai-test]$ mv adeos-linux-2.4.29-i386-r16.patch rtai3.2/base/arch/i386/patches/
  [/tmp/rtai-test]$ cd linux-2.4.29
  [/tmp/rtai-test/linux-2.4.29]$ patch -p1 < ../rtai-3.2/base/arch/i386/patches/adeos-linux-2.4.29-i386-r16.patch  
  • Build the linux kernel. linux-2.4.29.config is the kernel config we use.
  [/tmp/rtai-test/linux-2.4.29]$ make mrproper
  [/tmp/rtai-test/linux-2.4.29]$ cp ../mca2/etc/linux-2.4.29.config .config
  [/tmp/rtai-test/linux-2.4.29]$ make oldconfig
  [/tmp/rtai-test/linux-2.4.29]$ make dep bzImage modules
  [/tmp/rtai-test/linux-2.4.29]$ cd ..
  • Patch rtai3.2 with the mca2 patch and prepare for use with mca2:
  [/tmp/rtai-test]$ cd rtai3.2
  [/tmp/rtai-test/rtai3.2]$ patch -p1 < ../mca2/etc/mca2-rtai3.2.patch 
  [/tmp/rtai-test/rtai3.2]$ ln -s ../linux-2.4.29 linux
  • Build rtai3.2.
  [/tmp/rtai-test/rtai3.2]$ ./configure --with-linux-dir=/tmp/rtai-test/linux-2.4.29
  [/tmp/rtai-test/rtai3.2]$ ln -s rtai_config.h base/include/
  [/tmp/rtai-test/rtai3.2]$ make
