Success building CVS version of EMC

This has been a long time in the making....
In order to help others through the process, I have attached the step by
step
story of getting the 4Nov2000 cvs version of emc/rcslib downloaded,
compiled,
installed and running. Now I can back to coding...

The attached story assumes you have rtlinux up and alive... I also
recorded that story
if anyone is interested, but it is on paper not as a tutorial file.

Hope this helps those brave enough to challenge the CVS system.

# The Saga of Getting the EMC/RCSLIB CVS Code to Build and Run.
#
# At this point you should have installed Redhat 6.2 and
# patched a 2.2.14 virgin kernel with rtlinux_2_2a.
#
# some stats on system (P133/64mb and 3gb of scsi 2 drives)
# if you open this file in an editor, you can cut and paste the commands
# into a terminal window as required... or turn this into a script

[root@cnc src]# uname -a
Linux cnc 2.2.14-rtl2.2 #1 Fri Oct 20 21:02:22 PDT 2000 i586 unknown


# create directories for emc/rcslib project
[root@cnc src]# cd /usr/local
[root@cnc local]# mkdir nist
[root@cnc local]# cd nist

# grab a copy of all the cvs code - just hit 'enter' when asked for password
[root@cnc nist]# cvs -d:pserver:anonymous@...:/cvsroot/EMC login

CVS password:
[root@cnc nist]# cvs -z3 -d:pserver:anonymous@...:/cvsroot/EMC co -P emc rcslib

#grab a copy of the latest src tar file (includes some items missing from the cvs tree)
[root@cnc nist]# mkdir temp
[root@cnc nist]# cd temp
[root@cnc temp]# ncftp download.sourceforge.net
ncftp / > cd pub/sourceforge/emc
ncftp ...nts/u3/sourceforge/emc > ls

Save? (yes/no) n
ncftp> exit

# now untar the file so we have access to the contents
[root@cnc temp]# tar -xzvf emcsrc-11-Aug-2000.tar.gz

# move correct install file into top directory
# the CVS install in the emc directory isnt complete
# note: rcslib must be built before emc so that librcs exists.
[root@cnc temp]# cd ..
[root@cnc nist]# cp /usr/local/nist/temp/install ./


# copy the missing skel.tgz we need to set directory structure
[root@cnc nist]# cp /usr/local/nist/temp/emc/scripts/linux_2_2_14/skel.tgz ./

# Build the EMC install directory tree from the skel template
tar xzvf skel.tgz

# to get a warm comfy feeling, lets see what has happened so far
[root@cnc nist]# ls
emc install rcslib skel.tgz temp

# now try the builds
# see comment below...[root@cnc nist]# ./install
# 14 minutes to failure
# I could not get rcslib to build. I kept getting the following msg:
# In file included from rcsvers.cc:3:
# rcs_defs.hh:295: dbg_mem.h: No such file or directory
# to fix this, I had to edit /usr/local/nist/rcslib/src/rcs_defs.hh line 294
# and comment out as shown below or delete the line
# //#include "dbg_mem.h" // DEBUG_MALLOC, DEBUG_FREE
#

[root@cnc nist]# ./install
# rcslib takes about 14 minutes to build on my P133
# emc takes about another 16 minutes to build, a few warnings in dcmotor2.c
# nothing fatal
# you need to answer y to the 2 questions asked.

# now try the demo
[root@cnc nist]# cd emc
[root@cnc emc]# ./rs274ngc_new_sim.run
# click on ESTOP/Estop Off, Estop OFF/ Machine on, Manual/Auto
# click on Open.../cds.ngc/Open
# click on View/Backplot
# finally... click on run and watch the gcode roll....

# the above process takes a little over 1/2 hour... It took me 2 weeks
# to figure how to due this and to get it all to work... To bad I can't
# bill by the hour :}
