ZipSlack EMC install (long)

["bfp" <bfp-at-earthlink.net>]

hello all,
    I've been playing arround this weekend with installing EMC on the
ZipSlack mini-distro from Slackware 7.0

this is one way to build a small Linux distro with RTLinux and EMC
that can be installed on a windows hard drive without repartitioning
and can be burned onto a cdrom for distribution to others

these notes cover the full installation process to go from a windows only
system  to a dual boot windows/Linux+RTL+EMC  system
so its a bit long

system requirements:
PC running win9X
about 400Mb free hard drive space
stable internet connection

first download Zipslack from
ftp://ftp.slackware.com/pub/slackware/slackware-7.0/zipslack/zipslack.zip
unzip it to c:\ this creates a UMSDOS Linux filesystem in c:\linux
edit the c:\linux\linux.bat file to boot from hda1

then download these additional packages from
ftp://ftp.slackware.com/pub/slackware/slackware-7.0/slakware/

a11/tcsh.tgz  C shell needed by EMC install scripts

d1/ncurses.tgz  new curses libs needed by keystick
   glibc.tgz  some libs not included in zipslack

tcl1/tcl.tgz  the tcl/tk packages
     tlx.tgz
     tix.tgz
     tk.tgz

x1/xbin.tgz   the minimum Xf86 packages
   xcfg.tgz   config files for X
   xfnts.tgz  minimum font package
   xfsrv.tgz  X font server
   xlib.tgz  libs needed by X
   libc5x.tgz still used by EMC
   xpm.tgz  may not be needed,but small
   xset.tgz  X setup
   xprog.tgz  X programming libs
   xvg16.tgz  vga16 needed for resources and xset
   xsvga.tgz  generic svga server,works for most cards
    or pick a server that matches your hardware

xap1/tkdesk.tgz  a file manager/editor for X

and icewm.tgz from
ftp://ftp.slackware.com/pub/slackware/slackware-7.0/contrib/
for a light,fast window manager

these were all downloaded to
c:\zip_dl\

also grab
rtlinux-2.0-prepatched.tgz from
ftp://ftp.rtlinux.com/rtlinux/v2/

and emc-07-Jun-2000.tgz from
ftp://isdftp.cme.nist.gov/pub/emc/emcsoft/linux_2_2_13/

these two go into
c:\rtl_dl\ and c:\emc_dl\

note: the umsdos filesystem truncates long filenames
when reading from the windows part of your hard drive
so I've used wildcards and separate download directories
to keep things fairly simple

for a total download of about 90Mb
I pulled it all thru a 56k modem in less than a day
the whole thing expands to just over 378Mb installed

now from the win9X start menu select shutdown and
restart in MS_DOS mode this reboots to a DOS prompt
do not use a DOS box in windows
go to c:\linux and run linux.bat to load linux

(DOS prompt uses backslash "\")
> cd \linux
> linux

login as root
now to install the additional packages
(/DOS is the doorway to the rest of your hard drive under linux)

(Linux prompt uses slash "/")
# cd /DOS/zip_dl
# installpkg *.tgz

you may want to run the setup utility provided
by ZipSlack,this lets you configure your network,timezone,cdrom
terminal font,modem and serial mouse(PS/2 mice are autodetected)
I didn't bother to do this step and had no real problems
(optional)
# setup

now configure X

# xf86config

and select ICEwm as the default window manager

# xwmconfig
(ICEwm is the first selection so just hit <spacebar> then <enter> )

you can
# startx
now or keep going from the command prompt

put EMC in the right place and untar it

# mkdir /usr/local/nist
# cp /DOS/emc_dl/*.tgz /usr/local/nist
# cd /usr/local/nist
# tar -xzvf *.tgz

put RTLinux in the right place and untar it then
remove the old linux link and create the new linux link

# cp /DOS/rtl_dl/*.tgz /usr/src
# cd /usr/src
# tar -xzvf *.tgz
# rm linux
# ln -s rtlinux-2.0/linux   linux

OK now that everything is in the right place its time
to compile the real-time kernel

# cd /usr/src/linux
# make menuconfig
(or if you already started X)
# make xconfig

select the "load configuration from file" option
import the Zipslack default config file from /boot/config

under "cpu type and features"
change the cpu type to match your system
and select the hard real-time and smp options

make no other changes at this time,this will give you
a modular real-time kernel that will run on just about any
hardware

now compile the real-time kernel

# make dep ;make clean ;make bzImage
# make modules ;make modules_install

and replace vmlinuz and System.map

# mv /boot/system.map /boot/old_system.map
(note:the capitalization on the next line is correct)
# cp System.map /boot/system.map
# mv /vmlinuz /vmlinuz.old
# cp arch/i386/boot/bzImage /vmlinuz

Zipslack has no lilo.conf file to edit and rtl_2.0 does not use
the "append mem" line anyway so...
now is the time to reboot with

# reboot
or <ctrl>+<alt>+<del>

windows will restart automatically so you will have to
shutdown and restart in DOS mode again just like before
there will be some missing modules for pcmcia services when
Linux restarts but nothing that will keep RTL or EMC from working

log back in as root and make the real-time modules

# cd /usr/src/rtlinux-2.0/rtl
# make
# make install

you can make and run the real-time examples now if you want

now on to EMC
the emc-07-Jun-2000 release has four files that
wind up being misplaced during the initial install
this bash script will fix that for the second compile

------------cut-here---------------
#! /bin/sh
# filename fix
# fix for emc-07-Jun-2000 misplaced files
# place this file in the /usr/local/nist directory
# you may need to set executable permissions on this
# file with (# chmod 755 fix)
# this script will copy some files to the right
# directories so that the compiler can find them
cp emc/plat/linux_2_2_13/include/emcglb.h
emc/plat/rtlinux_2_0/include/emcglb.h
cp rcslib/plat/linux_2_2_13/include/inifile.h
rcslib/plat/rtlinux_2_0/include/inifile.h
cp rcslib/plat/linux_2_2_13/include/rcs_defs.hh
rcslib/plat/rtlinux_2_0/include/rcs_defs.hh
cp rcslib/plat/linux_2_2_13/include/dbg_mem.h
rcslib/plat/rtlinux_2_0/include/dbg_mem.h
------------cut-here---------------

to build EMC

# cd /usr/local/nist
# ./install
# ./fix
# ./compile

you can now go to the emc directory,edit the .ini files and run EMC

to distribute this system to others
reboot to windows
burn the whole c:\linux directory to a cdrom
label it ZipEMC

to install ZipEMC on a different system just pop in
the disk and copy the linux directory to c:\
then reboot to DOS,start Linux,login as root
and run xf86config to set up the new mouse and video hardware

you could also stay in Linux and uninstall or delete the
packages and files that are not being used to save some space
then reboot to windows and zip the linux directory back up

I haven't tried this yet but if you can trim the new zip file down to
about 50-60Mb without breaking Linux you may be able to put it
on an FTP site

Have fun,
