Building 32 bit Mozart for 64 bit Linux

[Kevin Glynn]

Dear hackers,

I accidentally bought a 64 bit machine at the weekend (;-)). Only a
small patch to mozart is required to build mozart in a 32 bit chroot. 
First: set up your 32 bit chroot, here are some sample instructions
for debian:
       https://alioth.debian.org/docman/view.php/30192/21/debian-amd64-howto.html#id271960

You must also copy your /etc/hosts to /etc/hosts in the chroot.

Mozart will fail to build successfully in this chroot because it
detects the platform as unknown-unknown and tries to link executables
with ld rather than gcc.  To fix this apply the following patch:

Index: share/bin/ozplatform
===================================================================
RCS file: /services/mozart/CVS/mozart/share/bin/ozplatform,v
retrieving revision 1.33
diff -r1.33 ozplatform
40a41,42
>    x86_64\ Linux\ *)    OZARCH=linux-i486   # Must build in 32 bit chroot!!!
>    ;;

Now you should be able to configure, make bootstrap and make install
as usual. Of course, you will need to run oz from inside the chroot
but you can wrap a script round oz to make this almost painless.

If we could automatically detect from configure that we are running
inside a 32 bit chroot we could add this fix to mozart but I don't
know if there is a standard way to detect that.

Hope this helps,
