testing without installing

[Paul Kienzle]

Here is a public domain script which I wrote to test a 
new version of octave without installing it.  Is there 
a better way to do this?

#!/bin/sh

if test "$1" = --help ; then cat <<EOF
Run the compiled octave without installing it.  Make sure you are in
the octave root directory before running.

This may not work if octave is configured using --enable-shared --with-rpath, 
and if you have already installed the current version. That's because the 
rpath specified in the binary takes precedence over LD_LIBRARY_PATH.  If 
you encounter this problem, you can:
   (a) use --preload as the first option to preload the libraries (this 
       works on Linux, but maybe not on other OSes),
   (b) reconfigure using --enable-static --disable-shared --enable-dl,
   (c) change OCTAVE_VERSION in src/version.h, reconfigure and recompile, or
   (d) reconfigure using --without-rpath and recompile (but you will need to
       reconfigure using --with-rpath and recompile before installing).

Octave is run without sourcing .octaverc first.  You can do this explicitly
on startup using source("~/.octaverc").
