OK.

 

I finally figured out how to specify to configure to use -m32 on the CFLAGS entries.  It is a part of the invocation of configure.

../../platforms/unix/config/configure CFLAGS="-m32 -g -O2 -msse2 -D_GNU_SOURCE -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0" LIBS=-lpthread

I seem to have gotten past the problem with sqUnixHeartbeat.c and now I have a new problem:

vm/vm.a(sqExternalSemaphores.o): In function `doSignalExternalSemaphores':
/home1/vawhigso/public_html/squeakelib/Cog/platforms/Cross/vm/sqExternalSemaphores.c:198: undefined reference to `sqLowLevelMFence'

gcc -E -dM should print predefined macros.  e.g.

McStalker.oscogvm$ gcc -m32 -E -dM platforms/Cross/vm/sqMemoryFence.h | egrep "86|GNUC"
#define __GNUC__ 4
#define __DBL_MAX__ 1.7976931348623157e+308
#define __i386 1
#define i386 1
#define __i386__ 1
#define __GNUC_PATCHLEVEL__ 1
#define __GNUC_MINOR__ 2
#define __GNUC_GNU_INLINE__ 1
McStalker.oscogvm$ gcc -m64 -E -dM platforms/Cross/vm/sqMemoryFence.h | egrep "86|GNUC"
#define __GNUC__ 4
#define __DBL_MAX__ 1.7976931348623157e+308
#define __x86_64 1
#define __x86_64__ 1
#define __GNUC_PATCHLEVEL__ 1
#define __GNUC_MINOR__ 2
#define __GNUC_GNU_INLINE__ 1

You'll then see what names are given to define x86/IA32 on your system.  You can then edit the following incantation to include your configuration (and let me know what it is).

 #if defined(__GNUC__) && (defined(i386) || defined(__i386) || defined(__i386__) || defined(_X86_))

The question is: is your OS 32 or 64-bit? The CPU doesn't matter here. If your OS is 64-bit then you'll probably need the gcc-multilibs package (or equivalent for your platform) and as Eliot suggested the -m32 switch for compilation and linking. To run the resulting VM, you'll need the ia32-libs package (or equivalent for your platform), but you already have that if you can run the prebuilt SqueakVM.
