[Axiom-developer] 20080107.01.tpd.patch (macosxppc port)

[daly]

This changeset enables building for the macosxppc platform. See
<http://axiom.axiom-developer.org/axiom-website/download.html>

The pseudo-terminals (/dev/pty) don't work so the hyperdoc/graphics fails.
This is still under study. The new browser-based hyperdoc will make this
problem disappear.

The )browse command works but you have to use the latest firefox because
safari does not seem to know about the http request object.

There is a nasty interaction between CVS and OSX. Apparently CVS won't
let you delete directories. OSX considers two names that differ only
by case to be the same thing. Axiom did a global downcase of all
filenames but CVS doesn't want to delete the directories so the uppercase
ones overwrite the lowercase ones. The fix is to use the sources from 
the axiom download page rather than from CVS.

To build the system you need to install xcode from 
<http://developer.apple.com/tools/download> and you need the path:
export PATH=/sw/bin:$AXIOM/bin:$PATH

Running the binary is the same as always:

cd axiom
export AXIOM=`pwd`/mnt/macosxppc
export PATH=$AXIOM/bin:$PATH
axiom
