Re: compiling multiple versions on one system

[Shai Ayal]

I do it all the time with no problems I have like 5 versions of octave 
currently installed. Things to remember:

* each time you do "make install" for octave, it places links in 
/usr/local/bin for octave,mkoctfile and some more files to the 
"versioned" files (i.e. octave -> octave-2.1.71), so typing "octave" on 
the command line will give you the last version installed. You can of 
course relink these files to your preferred version and you can always 
use the versioned filename (i.e type octave-2.1.71 at the command line)
* each time you install a new octave, you should recompile octave-forge 
for it. Just in case, remove the old octave-forge distribution directory 
and untar it again so that you don't have any old binaries floating around.

Octave forge uses the non-versioned versions of octave, mkocfile etc..., 
so my way of installing a new version is:

cd octave-x.x.x && ./configure && make && su -c "make install"
cd octave-forge-x.x.x && ./configure && make && su -c "make install"
now you can relink octave, mkoctfile etc...
