= Installing ASAP and dependencies from source =

 * '''Rpfits'''
  Download [http://www.atnf.csiro.au/pub/software/rpfits/rpfits.tar.gz rpfits]
{{{
   tar zxvf rpfits.tar.gz; cd rpfits/linux
   make install
}}}

 * '''CASA''' (aips++)
  Download [http://www.atnf.csiro.au/pub/software/asap/casa_asap.tar.bz2 casa_asap] (or [http://www.atnf.csiro.au/pub/software/asap/casa_asap2.1.tar.bz2 casa_asap2.1])
{{{
   tar jxvf casa_asap.tar.bz2; cd casa_asap
   sh configure.sh
        (read README and decide if you need to edit linux/UNKNOWN_SITE/makedefs)
   sh build.sh
}}}

  Depending on whether you use (t)csh
{{{
   source aipsinit.csh
}}} 
or bash
{{{
   . aipsinit.sh
 }}}

 * ASAP
  (You need to have subversion installed)
{{{
   svn co http://sourcecode.atnf.csiro.au/repos/asap/branches/Release2.1 asap2.1
   cd asap2.1
}}}

  You need to have the scons package installed (see o/s specific notes)
{{{
   scons
}}}

  If scons fails with {{{"Checking for casa libraries...no"}}} then you probably forgot to source 
  the aipsinit script. If any other check returns "no" please install the corresponding package on
  your machine.

  Now it's probably best to get the asap data repository.
{{{
   export ASAPDATA=.
   ./bin/asap_update_data
   unset ASAPDATA
}}}

  Install it to the default location:
{{{
   su
   scons install
}}}

 * ASAP Data
{{{
   su
   asap_update_data
}}}

Now you can test it by executing:
{{{
   asap
}}}

This will install the asap startup script in $PREFIX/bin and the python code on $ASAPPY/asap. To run you private version of asap you will need to set the PYTHONPATH environment variable to $ASAPPY/asap. To simplify your life it is recommended you edit $PREFIX/asap and add the lines (changed appropriately) near the beginning of the script:
{{{
  PYTHONPATH='/home/me/python'
  export PYTHONPATH
}}}
