ocamlnet library compiled without SHM support

[Seb Mondet]

Binary package hint: libocamlnet-ocaml

With ubuntu's version of ocamlnet, (Netsys.have_posix_shm ()) always gives 'false' which is not the expected behaviour on linux.

If I download the source (apt-get source), compile it and link with it, the function returns true.

In the sources, the script:
  ocamlnet-2.2.8.1/src/netsys/configure
is responsible for the '#define HAVE_POSIX_SHM'

$ lsb_release -rd
Description: Ubuntu 8.04.1
Release: 8.04

$ apt-cache policy libocamlnet-ocaml

It seems that the package has been built in an environment lacking /dev/shm, and therefore the test program failed, hence the value of Netsys.have_posix_shm.

AFAICT, this is an issue in Ubuntu building infrastructure, not in the package itself. I could make the package building fail if /dev/shm is not mounted... but it would then always fail in Ubuntu build farms... is that what we want?

[Stéphane Glondu (glondu)]

Actually, packages built with cowbuilder are also affected. I will force SHM on Linux.

Fix committed in pkg-ocaml-maint git
