Hi David, 

I attach some notes I made some months ago which may help,

  Best wishes

Some problems encountered when installing RTAI/RTLAB were solved as follows:
Peter Gawthrop Oct 1st 2003, October 2nd 2003.

1. Building patched kernel. (I used kernel 2.4.18 with RTAI 24.1.11
   a) Use gcc-2.95.4 (gcc-3.xx.xx fails with syntax errors)
   b) You need to compile your kernel with the following options disabled:
      i)  Symmetric multiprocessor
      ii) Local APIC Support on uniprocessor
      They are under "Processor Type and Features" 
    This prevents a nasty "APIC error" when insmoding rtai - 
    (https://mail.rtai.org/pipermail/rtai/2003-March/002955.html) 
   c) If changing kernel configuration options, do `make distclean' and
      `rm -rf /lib/modules/2.4.18-rtha15' before recompiling.
   d) Don't forget to include your ethernet card in the configuration.

2. Building RTAI 24.1.11 
   a) Enable UP
   b) Disable MUP and SMP
   c) Do ./setsched up after make and before make install
   d) The recommended 24.1.9 fails to compile - syntax errors.
   e) Use gcc-2.95.4 

3. Building RTLab (current CVS)
   a) Use g++-3.3 and gcc-3.3 (2.9 fails)

4. Building comedi/comedilib
   a) The latest versions do not work with my card (daqcard-1200) - so
      use  comedi-0.7.66 (NOT 67) and comedilib-0.7.20 (NOT 21).

   b) comedilib-0.7.20 is missing the etc dir containing the pcmcia
      startup stuff, so copy etc from comedilib-0.7.19 and thence copy 
      contents into /etc/pcmcia.

The relevant parts of /usr/src are:
