Subject: [Caml-list] caml_callback_exn problem
Date: Tue, 14 Sep 2004 17:31:57 -0500 [thread overview]

Hello all,
I have a question regarding interfacing ocaml to C.
I've pretty much gotten ocaml callbacks working with C, which is very
cool and all, but I have a small problem. I can't get caml_callback_exn
to work at all. To be specific, if I try to link a program, I get the
following result:
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.4/../../../../i686-pc-linux-gnu/bin/ld:
warning: type and size of dynamic symbol `caml_callback_exn' are not
defined
If I try to run the resulting executable, I get an "Illegal instruction"
message (SIGILL). Needless to say, the "normal" caml_callback calls work
fine. I'm using ocaml 3.08.1, just took a quick look at the sources.
Looked at asmrun/i386.S but can't seem to find anything out of the
ordinary. Am I not linking in a file I need?
What am I doing wrong here?
Any help is appreciated! Thanks,
James
