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.
