hello tim,
i want to disable the garbage collector, too. you wrote "This can be
done by setting USE_GC to 0 in object/id/libid.c". this does not work
for me. i did a fresh svn checkout of the repository, applied the change
to the libid.c file and called make. it compiles a lot of things but
stops in the function/objects directory (see output at the bottom).
what else did you do to get it working? did you use another version
instead of the HEAD revision? i am using linux with gcc 4.3.3. is this
maybe a problem?
regards,
ingo

Hi Mike,
I have encountered GC issues as well. I think an error message with
something about "GC_INNER_STACK_CLEAR" was displayed infinitely at the
end of my multithreaded programs... The quickest way to solve that
problem was to simply disable the garbage collector, which is what
I've done. (This can be done by setting USE_GC to 0 in object/id/libid.c)
However, I've also discovered that the GC already should have
multithreading support. I thought the only change I needed to make was
to add the flags "-DGC_LINUX_THREADS -DPARALLEL_MARK
-DTHREAD_LOCAL_ALLOC" to the CFLAGS variable in object/gc6.7/Makefile.
Just doing that didn't seem to be sufficient though, since the gcc
linker complained about every call to the pthreads library. I'm
guessing I should add another -lpthread flag somewhere, but I haven't
figured out yet where exactly...
Cheers,
Tim

Hi, i find this intersting. I had made a start a while back on trying
to naively integrate pthreads into COLA. I got distracted from that
but at the time got stuck with what I thought were GC issues. Has
this been a problem for you? do you do anything specific in your build
for multi-threaded GC support.
many thanks,
Mike
