Re: [Emc-users] BDI

[Paul <bd...@nt...>]

OK Tony

A list of files you'll need to grab before doing any work..

A virgin 2.4.xx kernel from www.kernel.org - The 2.4.21 will be fine.
The CVS sources for RTAI from www.rtai.org - I'd suggest using the Stromboli 
branch.
Finally, the EMC sources from www.sourceforge.net/projects/emc - Again, use 
the CVS sources, checking out rcslib and emc.

Make sure you have installed compat-egcs and the support libraries from the 
RH7.2 CDs along with tcl, tclx and tk. Now follow the steps..

a) rename /usr/bin/gcc to /usr/bin/gcc-2.96
b) create a symlink /usr/bin/gcc pointing to /usr/bin/kgcc
c) extract your kernel sources in /usr/src
d) create a symlink /usr/src/linux pointing to the kernel sources (at a 
guess) /usr/src/linux-2.4.21
e) move the RTAI sources to /usr/src
f) and create a symlink /usr/src/rtai pointing to /usr/src/stromboli
g) patch the kernel with either the rthal OR the adeos patch with the command
  patch -p1 < /usr/src/rtai/patches/patch-2.4.21-rthal5g

Now on to the hard work...

h) Use the attached config, placing it in /usr/src/linux
i) In the /usr/src/linux directory, do a "make oldconfig"

Now do the usuall make dep clean bzLilo modules modules_install steps.
 I usually use bzlilo and then move the vmlinux and System.map to /boot when 
it is finished.
With RH7.2, you'll probably need to run mkinitrd before configuring and 
executing lilo... Now reboot with your new kernel..

l) Changing to /usr/src/rtai, copy the attached rtai.config across as .config
j) Do a "make menuconfig" and quickly exit.
l) Do the "make dep && make" followed by "make dev", "./setsched up", and 
"make install".
m) With the rcslib and emc sources in /usr/local, change to 
/usr/local/rcslib/src
n) Do a "make PLAT=linux_rtai" and "make PLAT=rtai"
o) in the /usr/local/emc/src directory, do the same two "make 
PLAT=linux_rtai" and "make PLAT=rtai"..

Assuming no fatal errors, you now have a fully functioning EMC.

Apologies if these instuctions sound too pedantic, but they may end up in one 
of the handbooks at some point. If there are any stages that have you 
confused, just ask either here or on the irc channel.

Regards, Paul.
