Hi,

I assume you must have some form of internet connection as you are

emailing me. I would highly recommend installing gcc using yum if at

all possible. Also, this thread is starting to diverge from EPICS,

perhaps visiting RHEL or general linux forums would help with your

initial system setup.

I have just noticed i don't have gcc installed. what is more i don't

have the internet connection to install it using yum. Are there any

other ways I can figure this out?

        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.

                       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.
