Re: [Caml-list] Re: Dynlinking plugins defining the same unit name but with different implementations.

Now on Linux 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11 07:54:58 UTC
2010 i686 GNU/Linux

with exactly the same code that know works on osx and ocaml 3.12 from
svn. I get the following problem when running my test program.

error loading shared library:
/home/dbuenzli/sync/dynlinkt/_build/a/a.cmxs: undefined symbol:
camlPervasives__$5e_1112
error loading shared library:
/home/dbuenzli/sync/dynlinkt/_build/b/b.cmxs: undefined symbol:
camlPervasives__$5e_1112

I tried to add /usr/local/lib/ocaml to LD_LIBRARY_PATH but without
success. Any hint ? Is that a bug or am I missing something ?

Thanks for your help,

Daniel

P.S. Here's how these things are compiled by ocamlbuild
