I would recommend a visit to the EPICS site.

    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.
