================================================================================
To install a precompiled ARB
================================================================================

1. download the needed files from our homepage http://www.arb-home.de/
   and save them into a directory of your choice (i.e. ~/arb-download/ )

   Files needed: 'arb-*.tgz' and 'arb_install.sh'
                 (see arb_README.txt for details on different versions)

2. if you like to install arb for all users, become superuser (root).

3. run the arb installation script with the following commands

       cd ~/arb-download
       bash arb_install.sh

   and follow the instructions.

4. Install packages needed by ARB:

--------------------------------------------------------------------------------
4a. If you're using Ubuntu please refer to:

  * the detailed list of packets to install for ARB:    arb_UBUNTU.txt
  * the package-install-script for ubuntu:              SH/arb_installubuntu4arb.sh

--------------------------------------------------------------------------------
4b. If you're using debian please install one of the centos versions

You may also want to use 
  * the package-install-script for ubuntu:              SH/arb_installubuntu4arb.sh
(Note: add 'contrib non-free' behind 'main' in /etc/apt/sources.list)

--------------------------------------------------------------------------------
4c. Otherwise use your package manager to install the
    software that is needed to run ARB:

- (open)motif
- bash
- libpng
- xterm
- libxerces-c3.1

Only needed for Open GL version:

- OPENGL
- libGLEW -- Open GL extensions library (see subdirectory lib/addlibs)


Software that is useful together with ARB:

- gnuplot
- xreader (or gv)
- xfig (+ fig2dev to print from xfig)
- xterm
- transfig
- perl5
- treetool

--------------------------------------------------------------------------------
If you get errors about missing libraries when calling arb, have a look if there
are different versions of the missing libraries in /usr/lib and create a link
there.

Most likely you'll be missing libXm.so.4, so the following example describes
how to solve the problem for that library:

    # as superuser:
    cd /usr/lib
    ln -s libXm.so.4 libXm.so.3


================================================================================
To build ARB from source
================================================================================

1. download the needed files from our homepage http://www.arb-home.de/
   and save them into a directory of your choice (i.e. ~/arb-build/ )

   Files needed: 'arbsrc*.tgz'

2. Unpack the source

   e.g.
        tar -zxvf arbsrc.tgz

3. Goto source dir

   e.g.
        cd arbsrc_6213

4. Set up compile environment

   if you're using bash:

      export ARBHOME=`pwd`
      export PATH=$ARBHOME/bin:$PATH
      export LD_LIBRARY_PATH=$ARBHOME/lib:$LD_LIBRARY_PATH

5. Now either

   a. run

        make all

      to compile arb. On a multiprocessor machine you may want to call

        make -j5 all

      or similar (where the number should be the number of processors + 1).

      This will fail on first call telling you to edit config.Makefile.
      Open that file in your editor and check whether the default values
      suit your system and needs.

      If you like to activate openGL features set OPENGL to 1
      (needs additional libraries).

      When done, again call one of the make commands mentioned above.

      If compilation fails, have a look at the packages needed for compilation
      below. For ubuntu/debian there is a script for automated package
      installation in

             SH/arb_installubuntu4arb.sh

      Once compilation succeeds, call

        arb

      to run arb in compilation directory.

   b. run

        make tarfile
        bash arb_install.sh

      to install arb for all users

   and follow the instructions there.
