Fw: [Caml-list] Thread library

Ok, after a long search I did find where it was written. After installation
of ocamelwin one has to read the readme win file .

There one says that there are no threads  for Cygwin Ocamel  but there are
threads for Mingw Ocamel and of course for MVSC6.0
 Ocamel .

I hope this information is still correct allthough I don't understand the
why: what is the difference between Mingw and Cygwin?

Thx

Scott

Hi,

I have looked in the reference manual. But there is some thing that
surprises me: The thread library is not available for Unix an Cygwin Windows
but is available for Windows MVSC6.0 and MINGW Windows.

Is this true or have I misread something?

Thx

Scott

The Cygwin port of OCaml is just the OCaml Unix sources compiled and
linked against the Cygwin "Unix compatibility" libraries.  The latter
do not (yet?) provide a Unix-compatible thread library, hence no
threads in OCaml-Cygwin.

The Mingw port of OCaml is the OCaml Win32 sources compiled by
Cygwin/Mingw and linked against the native Win32 libraries, which
include Win32 threads.  Thus, OCaml-Mingw supports threads via Win32.
