I am trying to build the Boehm Garbage Collector under FreeBSD, and am
having trouble, starting with the undefined reference to '_GC_push_one'
when I 'make test'. I will keep slogging, but if there's anyone out
there who has trod this path before me, any assistance is appreciated.

This should work, but I don't normally test on FreeBSD.

I assume this is an ELF system, and C names aren't supposed to have a
prepended underscore? If so, there shouldn't be any references to
_GC_push_one. The code in GC_push_regs (mach_dep.s) in the

( defined(I386) && defined(__FreeBSD__) && defined(__ELF__) )

case, should generate calls like

asm("pushl %ebx"); asm("call GC_push_one"); asm("addl $4,%esp");

This is probably not the best way to do things, but it shouldn't
generate references to _GC_push_one. Thus there is either an unexpected
reference from elsewhere, or one of the expected macros is not getting
defined.

If you need more information, please send mail to

The reply by Hans Boehm and email from other helpful souls made me
realize I was running an outdated version. There is a port already of
the GC, and it works great. Another score for FreeBSD!
