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.<br>
<br>
../../platforms/unix/config/configure CFLAGS="-m32 -g -O2 -msse2 -D_GNU_SOURCE -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0" LIBS=-lpthread<br>
<br>
I seem to have gotten past the problem with sqUnixHeartbeat.c and now I have a new problem:<br>

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.<br>
