Snow Leopard Worries

[Jasper Taylor]

Hi Daniel and crew,
I recently updated my MacBook to Snow Leopard, and now have some problems.
While the Prolog executables I built previously with OSX 10.5 still run 
OK, I cannot build new ones. Here is a simple example to show the sort 
of errors I am getting. This is using gprolog 1.3.1.
File test.pl:
main :-
   write('Hello World!'), nl.

compilation failed

...so, I attempted to compile it under Snow Leopard to see if a new 
build would fix the problem. I downloaded the latest 'unstable' source 
code and ran 'configure' OK, but then:

jaspert$ make
(cd EnginePl; make config)
gcc -march=i486 -O3 -fomit-frame-pointer  -o pl_config pl_config.c
pl_config.c:1: error: CPU you selected does not support x86-64 
instruction set
pl_config.c:1: error: CPU you selected does not support x86-64 
instruction set
make[1]: *** [pl_config] Error 1
make: *** [all] Error 2

I had a look at the INSTALL file to see if there was any mention of 
setting the architecture, and tried configuring with --disable-regs. 
This made no difference. I would like to be able to build prolog 
executables on OSX 10.6 that work on 10.5 and 10.4 -- currently even on 
10.5 I cannot build one that works on 10.4. I would be quite happy if it 
was all 32-bit!

Any help much appreciated
