[Caml-list] Cygwin & dynamic loading

[Christian.Schaller@siemens.com]

Hi there,

Can anybody give me some enlightenment (so that I can sleep better again)
about the Cygwin port of OCaml.  I am running this port since version 3.04
and never encountered the following error message until I installed my
Windows system from scratch:

$ ocamlmktop -o ocaml-str str.cma
Error on dynamically loaded library: dynamic loading not supported on this
platform

I remember I was running ocamlmktop this several times on my old system, but
now it doesn't work anymore.  When checking the configure script, I noticed
that there's no *-*-cygwin section on shared libraries, so it's obvious that
shared libraries will not be supported.  But why did above command work just
fine on my old system?

Am I missing some Cygwin library or do I have to patch the configure script?
Does the native Windows OCaml installation interfere with the Cygwin port
(that's the only obvious difference between the two systems).

Thanks a lot!
- Chris
