Re: [Swarm-Support] Re: Swarm 2.2 on Intel (and PPC) Mac OSX Tiger

[Brandon M. Gabler]

Well, I got one step further with those suggestions; I realized that I had not
changed the -arch ppc lines again after I reinstalled the swarm packages.

I have double-checked that I changed everything the swarm FAQ instructs us to
change, and I have a new error:

/usr/bin/ld: warning Heatbug.o cputype (7, architecture i386) does not match
cputype (18) for specified -arch flag: ppc (file not loaded)
/usr/bin/ld: warning HeatSpace.o cputype (7, architecture i386) does not match
cputype (18) for specified -arch flag: ppc (file not loaded)
/usr/bin/ld: warning main.o cputype (7, architecture i386) does not match
cputype (18) for specified -arch flag: ppc (file not loaded)
/usr/bin/ld: warning HeatbugModelSwarm.o cputype (7, architecture i386) 
does not
match cputype (18) for specified -arch flag: ppc (file not loaded)
/usr/bin/ld: warning HeatbugObserverSwarm.o cputype (7, architecture 
i386) does
not match cputype (18) for specified -arch flag: ppc (file not loaded)
/usr/bin/ld: warning HeatbugBatchSwarm.o cputype (7, architecture i386) 
does not
match cputype (18) for specified -arch flag: ppc (file not loaded)

...more warnings here, then:

/usr/bin/ld: Undefined symbols:
___objc_class_name_HeatbugObserverSwarm
collect2: ld returned 1 exit status
make: *** [heatbugs] Error 1

I have checked my env variables through bash, and the path to swarmhome,
swarmhome itself, and display are set to the required settings.

Thanks for all the help thus far, it seems as though progress is being 
made, and
hopefully this discussion will help others along the way!

Take care,
Brandon
