Re: [Emc-users] Problem compiling latest CVS files

[Kenneth M. <co...@gr...>]

Tim -

Here's my notes on the last time I compiled EMC - many may find them to 
complex and your mileage may vary, but it worked for me on 3 different 
setups.

KenMc

Need - specific version information for each component
Good idea to read: emc/doc/emcsoft.html

EMC compile and install Redhat 9.0

Load RH90 with all (although I read through each option looking for 
TCL/TK related options)
insure that TCL/TK are loaded
look specifically for tclExtend.h
the programs below ASSUME tclExtend.h and fail badly when it is missing

Download and patch per Johnathon Stark instructions
(or use your backup of those files)

Top directory for installation was /usr/src

cd /usr/src
Get kernel for linux-2.4.22
tar -xvf ./linux-2.4.22*gz or bz2 depending on which compressed file 
you downloaded

cd /usr/src
export CVSROOT=":pserver:gu...@cv...:/opt/cvsroot/rtai"
cvs login
(password is anoncvs)
cvs -z3 co stromboli
  (at this point the directory stomboli is created and the files are 
downloaded)
cvs logout
cd /usr/local/src
tar -xvf linux-2-4-22.tar (assumes already uncompressed)

cd linux-2-4-22
patch -p1 < ../stromboli/patches/patch-2-4-22-rthal5g
  	# you should get a list of 'patching file...' statements
	# or an error message that this has already been done

cd /usr/src

# what are the specific versions here?
export CVSROOT="pserver:ano...@cv...:/cvsroot/emc"
cvs login
   (hit return for password)
cvs -z3 co emc
cvs -z3 co rcslib
cvs logout

#NOW BACK IT UP
Now tar -cvf /usr/local/src - (includes gcc source and object dir)
saved to Mac as 20040220_emcbase: emcbase.tar.gz
written to CD (almost 300 mb)

# BACK UP /usr/src at this point!!!!
# you won't need to download or run the patches again if something fails

Download and install gcc-2.95.3 (per comment in Stromboli source)
specific instructions
get extensions by running 'gcc -v' - use everything but the reference 
to Redhat
./configure ---- with extensions
make bootstrap ---- with extensions

add /sbin to the path - do a which ksyms and make sure it's there - one 
of the scripts uses this to find the realtime system

 From here the first job is to install the linux RTAI or RTHAL version
It is a combination of linux-2.4.22 and stromboli and can be done 
without emc or rcslib
But, from what I can tell the installation of emc and rcslib both 
depend on having RTHAL up and running

cd /usr/src/linux-2.4.22
make menuconfig
	change:
	load /boot/    current version config file
	disable set version information on all module symbols
	disable power management
	disable crypto (this is a proprietary Redhat product - you can't 
compile a new kernel if you include it)
	check that RTHAL is enabled (if it's missing you did something wrong 
when patching linux-2.4.22)
	exit and save config

make dep
make; make modules;make bzImage

cd ../stromboli
./configure
--- when it asks for the linux source tree - enter the full path:
	/usr/src/linux-2.4.22

make clean
make dep && make
	# this says 'make dep if anything but 0 is returned, then run make

append 'prune rtaisyms' to the file /etc/modules.conf

./setsched up
	# if there are errors above - this will complain - otherwise it 
outputs 2 lines
	# the lines refer to 'rtai_sched_up.o' and 'rtai_lxrt_old.o' being 
modified
	# each line ends in '....done'

make install

make dev
	# if you''ve been here before these devices already exist - this 
doesn't seem to be a problem

## Break from other instructions
# install and boot to the RTHAL realtime linux
# some of the code that follows is sensitive to RTHAL kernel being up 
and running
# if you're not in RTHAL the compile messages will have the line 
'-DNO_RTAI'  when they should say '-DHAVE_RTAI'

cd /usr/src/linux-2.4.22
make modules_install
make install

# cold reboot the system and start RTHAL -- BACK IT UP

cd /usr/src/rcslib/src
add /sbin to the PATH
export RTAIDIR=/usr/src/stromboli
export EMCSRC=/usr/src/emc

ln -s /usr/src/linux-2.4.22 /usr/src/linux

make PLAT=rtai_24_1_12
	# this makes a specific definition file found in 'rcslib/etc'
	# the plus to this is that it is pretty solid
	# the minus is that if your system varies from that definition you can 
get all sorts of very weird results

	# when this runs there's lots of copies
	# look for -DUSE_RTAI in the compile statements

make PLAT=linux_2_4_21
	# that's right '21'  - remember, you're using a previously defined 
definition file, again in rcslib/etc
	# this def is combined with generic.def in the same directory and used 
to make the rcs product

	# must see -DHAVE_RTAI  in the compile statements
	# if you see -DNO_RTAI you have a problem - possibly you didn't boot 
to the RTHAL system?
	# perhaps the system can't find 'ksyms'?

cd /usr/src/emc/src

make PLAT=rtai_24_1_12
make PLAT=linux_2_4_21


Finally do these links - if you don't you'll get bizarre errors when 
you try to run emc


# 2nd compile did'nt require this!!
export LD_LIBRARY_PATH=/usr/local/lib

cd /usr/src/emc/plat

ln -s ./linux_2_4_21 ./linux_rtai
ln -s ./linux_rtai ./nonrealtime
ln -s ./rtai_24_1_12 ./rtai
ln -s ./rtai ./realtime


cd /usr/src/emc
./sim.run

Whew....
