Pavel,

I just noticed you are building for 64 bit so you don't want EPICS_HOST_ARCH=linux-x86 you probably want
EPICS_HOST_ARCH=linux-x86_64

Sorry about that.

OK, then to install base I would do something like the following:

Setup a BASE location export

export BASE=/path/to/base

(Be warned I use "rm -rf" in places below as I have lifted this from a script.  This is a recursive forced remove and could potentially delete many files).
The lines below basically unpack the source code into two subdirectories base and extensions.  I would set BASE to something like

export BASE=~/applications/epics/R3-14-12-1

Then enter the following lines (or run from a script)

 rm -rf $BASE/base
 cp ./baseR3.14.12.1.tar.gz $BASE/baseR3.14.12.1.tar.gz
 gunzip $BASE/baseR3.14.12.1.tar.gz
 tar -xvf $BASE/baseR3.14.12.1.tar -C $BASE
 rm -f $BASE/baseR3.14.12.1.tar
 mv $BASE/base-3.14.12.1 $BASE/base
 # Unpack the extensions sources
 cp ./extensionsTop_20070703.tar.gz $BASE/extensionsTop_20070703.tar.gz
 gunzip $BASE/extensionsTop_20070703.tar.gz
 tar -xvf $BASE/extensionsTop_20070703.tar -C $BASE
 rm -f $BASE/extensionsTop_20070703.tar
 # Update the EXTENSION_MSI link in the Makefile
 sed "s/^EXTENSION_MSI.*/EXTENSION_MSI = msi1-5/" $BASE/extensions/src/Makefile > Makefile.tmp
 mv Makefile.tmp $BASE/extensions/src/Makefile
 # Unpack the msi extension sources
 cp ./msi1-5.tar.gz $BASE/extensions/src/msi1-5.tar.gz
 gunzip $BASE/extensions/src/msi1-5.tar.gz
 tar -xvf $BASE/extensions/src/msi1-5.tar -C $BASE/extensions/src
 rm $BASE/extensions/src/msi1-5.tar

The files I used above are
baseR3.14.12.1.tar.gz
extensionsTop_20070703.tar.gz
msi1-5.tar.gz

Then...

# Export the required variables
export EPICS_BASE=$BASE/base
export EPICS_HOST_ARCH=linux-x86
export PATH=$PATH:$EPICS_BASE/bin/linux-x86
export PATH=$PATH:$EPICS_BASE/../extensions/bin/linux-x86

 cd $BASE/base
 make
 make install
 cd $BASE/extensions
 make
 make install


I'm sure there are better instructions in the many manuals and tutorials that exist for EPICS.

Thanks, I'd figured this already :))

       Hello everyone!

       How can I set the environment variables (PATH and
       EPICS_HOST_ARCH) in RHEL-5 64 bit?
       I ran the EpicsHostArch.pl script (>> perl EpicsHostArch.pl),
       but this script only returns the variable, doesn't set
       anything. I check by running "dev" in the command line.

       And generally, what should one do to install the epics base
       from scratch on a linux machine?
       Thanks.


       Pavel.
