Ocaml and pthread_atfork()

Tony Breeds — 2012-04-17T03:02:29

Hi All,
Firstly I apologize if this is noise.  I elected to not file a
bugzilla as the problem seems to be powerpc specific and with the limited
resources for Fedora developers it would seem unfair.

I was recently trying to build a "current" libguestfs from the f16
branch[1].  During the build I hit:

(extracted from rpmbuild)

[tony< at >sneetch ~]$ bash -x  tmp/ocaml-test.sh 
+ cd rpmbuild/BUILD/libguestfs-1.16.9/ocaml/
+ LD_LIBRARY_PATH=../src/.libs
+ ocamlfind ocamlc -g -warn-error CDEFLMPSUVYZX -I . -package unix,threads -thread -linkpkg mlguestfs.cma t/guestfs_070_threads.cmo -o t/guestfs_070_threads.bc
File "_none_", line 1, characters 0-1:
Error: Error on dynamically loaded library: /usr/lib64/ocaml/stublibs/dllthreads.so: /usr/lib64/ocaml/stublibs/dllthreads.so: undefined symbol: pthread_atfork

I did a quick bit of googling and found:
http://ryanarn.blogspot.com.au/2011/07/curious-case-of-pthreadatfork-on.html

which seems to explain what's going on to my naive eye anyway.

I've tried a few different

Be helpful if you could say what the error was.  I just
compiled a lablgtk program on F16 and it compiled and linked
fine, so I'm doubtful that rebuilding lablgtk was more than
just a coincidence.

Nevertheless I've rebuilt it for you:

I misspoke, they are still discussing fixing it in this thread: 

http://www.mail-archive.com/caml-list< at >inria.fr/msg02104.html

"OCaml 3.13 will provide options for Hashtbl allowing it pass a seed, but
only in a case by case way. What will not be included in OCaml 3.13 is
access to RNGs with entropy injection (i.e. it is left to the programmer
to solve this difficulty)."

(In reply to comment #2)

Where is this email?

Anyway, upstream haven't started fixing it.  There is
opposition from people who want Hashtbl to work
reproducibly (naturally without them having to make any
changes to their code nor to their workflow).

We ship the ocaml language so ideally we need to fix it for our customers that
do use it. Emailed ocaml to confirm if they're done fixing it.

Review request for bringing back ocaml-calimages

Bruno Wolff III — 2012-02-23T17:27:39

I want to bring back ocaml-calimages since it is a build dependency
of free tennis. I used the current ocaml template mixed a bit with the
previous spec file to create the proposed new spec file.

While I'd really like an official review, even a quick looksee from someone
that works with ocaml regularly (which I don't), for obvious issues
would be appreciated.

Thanks.

The review bug is at:
