Please do the following:

  copy the original Makefile as Makefile.org
  copy the new Makefile as Makefile.new
  diff -Naur Makefile.org Makefile.new >Makefile.patch

and send me the patch file.

curious.

Generally what I do is the following (as root):

cd /usr/local/bin
echo 'export AXIOM=/usr/local/axiom/mnt/linux' >axiom
echo 'export PATH=$AXIOM/bin:$PATH' >>axiom
echo '/usr/local/axiom/mnt/linux/bin/axiom' >>axiom
chmod a+x axiom

That sets up an axiom command and also presets the AXIOM and PATH 
shell variables. Be sure to use single quotes with the above otherwise
the $PATH variable will be prematurely expanded.

no prob.

The 'axiom' command in the mnt/linux/bin directory is actually a shell
script. It ends up executing 'AXIOMsys' which is the binary. If you 
just want to run commands the AXIOMsys command can be piped:


Try the following:

cd /tmp
echo "1+1" >in
AXIOMsys <in >out
cat out

alternatively you can execute things from ".input" files. Create a file
called foo.input that contains a series of commands. Suppose foo.input
contains:

2+2
3+3

you can execute this input file with

echo ")read foo.input" | AXIOMsys
