[Caml-list] OSX 32bit, native dynlink?

[Benoît Pin]

Hi everybody,

is it possible to build ocaml 32bits in OSX with native dynlink support?

We were trying to build camlp4 (opam install camlp4) in OSX 10.10.3 with a 32bit ocaml runtime (opam switch 4.02.1+32bit) but it fails with:

# + /Users/pinbe/.opam/4.02.1+32bit/bin/ocamlopt.opt dynlink.cmxa -g camlp4/config/Camlp4_import.cmx camlp4/config/Camlp4_config.cmx camlp4/boot/Camlp4.cmx camlp4/boot/camlp4boot.cmx -o camlp4/boot/camlp4boot.native
# File "_none_", line 1:
# Error: Cannot find file dynlink.cmxa

indeed, it seems that we are doing something wrong and the 32bit version of Ocaml is built by opam without native dynlink support:
