Installing GDL

http://gnudatalanguage.sourceforge.net/

GDL is an IDL clone. To install on Fedora Core 3:

• Install packages gsl and gsl-devel using yum
• Download plplot-5.5.3 and gdl-0.8.11, unpack them
• Configure, compile and install plplot:

  ./configure && make && make install

• Configure gdl. I install in $HOME/opt, so change directories as appropriate:

  ./configure --prefix=$HOME/opt/gdl-0.8.11 --with-Magick=no --with-hdf=no \
  --with-hdf5=no --with-plplotdir=$HOME/opt/plplot-5.5.3 --with-netcdf=no \
  --with-python=no

• Then compile and install as normal:

  make && make install

• If necessary, add the GDL bin directory to your path:

  export PATH=$PATH:$HOME/opt/gdl-0.8.11/bin

• To test, type:

  $ gdl
  GDL - GNU Data Language, Version 0.8.11
  For basic information type HELP,/INFO
  'GDL_STARTUP'/'IDL_STARTUP' environment variables both not set.
  No startup file read.
  GDL> x=5
  GDL> print, x
         5
  GDL>
