[Caml-list] Packaging a caml library a DLL

[Caml-list] Packaging a caml library a DLL

[Ohad Rodeh]

List,
   I'm having a lot of trouble packaging a caml library (Ensemble) as a
DLL on win32.  Creating a win32 static library is easy, shared libraries on
Unix
are a breeze, however, win32 DLLs are really problematic.

   Has anybody been able to do this? any example makefiles?

Thanks,
      Ohad.

Here's the Makefile Harry Chomsky & me are using for the Win32 API.
Look at "dynamic" built.
It's working without any problem with bytecode compilation. However, native
compilation with DLL won't work due to the need to link with ocamlrun.lib.

CamlIDL contains a shell script that does just this in order to
package Caml code as a COM DLL.  You can view the script here:

http://camlcvs.inria.fr/cgi-bin/cvsweb.cgi/bazar-ocaml/camlidl/tools/camlidldll.tpl

The script contains some COM-specific stuff, but not much.

Hope this helps,
