Downloading and installing SPAM

Here are some instructions on how to install SPAM on your Linux 64-bit system. If you want to install it on some other Unix-based system, you're on your own :-).


Download SPAM and dependencies

An installation of SPAM on Linux requires at least the following items:

  • The latest SPAM package, found here
  • SPAM support files, found here
  • AIPS version 31DEC13 (LNX64 binary tarball with extras), found here
  • ParselTongue version 2.3 (with changes), found here
  • Obit core (LNX64 binary with changes), found here

The following necessary items are often already available on a standard scientific Linux installation:

  • Python version 2.7 (plus C include files)
  • Python packages: pylab / matplotlib, numpy, scipy, astropy
  • gcc
  • make
  • swig
  • optional: mencoder / mplayer (for making phase screen movies)
  • optional: ImageMagick convert (for making phase screen movies)

Install SPAM

Make a new directory that will hold all spam software

In your Linux shell, type

cd <local software path>
mkdir spam
cd spam

Move the downloaded tarballs to here.

In your Linux shell, type

mv <download path>/AIPS_<version>.tgz .
mv <download path>/parseltongue-<version>.tgz .
mv <download path>/obit_<version>.tgz .
mv <download path>/spam_<version>.tgz .
mv <download path>/spam_etc_<version>.tgz .

Install SPAM support files

> tar xzf spam_etc_<version>.tgz

Edit setup file(s) and modify SPAM_PATH to point to <local software path>/spam, SPAM_HOST to your machine name in capitals, and PYTHON to point to your python2.7 executable

gedit setup.*sh

Next, run the setup file. In Linux bash (sh) this is done through:

. setup.sh

In Linux C-shell ([t]csh) this is done through:

source setup.csh

Install AIPS

In your Linux shell, type

tar xzf AIPS_31DEC13.tgz
cd AIPS

These next two steps may not apply to you, but must be executed when you have installed and/or run AIPS locally.

mv ~/.AIPSRC ~/.AIPSRC_previous
mv ~/.dadevs ~/.dadevs_previous

Then start the actual install

perl install.pl -n

Here's how to quickly get through the AIPS installation

screen 0: <enter>
screen 4: <enter>
screen 4b: <enter>
screen 5: <e.g., your institute name in capitals (no spaces), and enter>
screen 5a: <enter>
screen 5b: <check that this is set to LNX64, and enter>
screen 6: <enter>
screen 7: <copy/paste suggested path and enter>
screen 8: <2x enter>
screen 9: <enter>
screen 9B: <enter>
screen 11: <2x enter>

And during installation: <3x enter>

Now we need to increase number of interactive AIPS sessions to 32. In your Linux shell, type n Linux bash (sh)

. LOGIN.SH

or in C-shell ([t]csh)

source LOGIN.CSH

Then

RUN SETPAR

In SETPAR

2 <enter>
10 <enter>
32 <enter>
-1 <enter>
AMANAGER <enter>
4 <enter>

Test AIPS by entering

aips tv=local

In AIPS POPS terminal, enter

11 <enter>
print 2+2 <enter>
kleenex <enter>

Exit AIPS directory

cd ..

Install Obit core

In your Linux shell, type

tar xzf obit_<version>.tgz

Install ParselTongue

In your Linux shell, type

tar xzf parseltongue-<version>.tgz
cd parseltongue-<version>
sh ./configure --prefix=${SPAM_PATH}/ParselTongue --with-obit=${SPAM_PATH}/Obit

This should return without errors (see below if it can't find obit). Then type:

make install
cd ..

Install SPAM package

In your Linux shell, type

tar xzf spam_<version>.tgz
cd python/spam

Edit the makefile so that the SWIGFLAGS and CCFLAGS point to the correct Python C header file directory (will contain Python.h; typically something like /usr/include/python2.7).

gedit makefile
make
cd ../..

And that's all folks!


Obit is missing?

The ParselTongue configuration may give you the following error message:

checking for Obit... missing
configure: error: Obit is not available

This is likely to be caused by a missing python package, not because Obit is missing (the script looks for Obit.so in the ${SPAM_PATH}/Obit/python/ directory. To find what is causing the problem, please do the following:

In bash:

export PYTHONPATH=${SPAM_PATH}/Obit/python:${PYTHONPATH}

Or in (t)csh:

setenv PYTHONPATH ${SPAM_PATH}/Obit/python:${PYTHONPATH}

Then

${PYTHON}

And in python:

import OSystem, OErr

Something will fail here, probably a missing python package or a missing library. Some of the missing libraries can be found here.
