[Caml-list] Windows install

[Caml-list] Windows install

[Jon Harrop]

I've been trying to install OCaml on Windows Vista using the OCaml 3.11.0
binary (MSVC) install. I have Visual Studio 2010 installed which, I believe,
satisfies the dependencies but I keep getting linker errors. Curiously,
different errors each time I reinstall:

C:\Users\Jon\Documents\OCaml>ocamlopt test.ml -o test
** Fatal error: Cannot find file "libws2_32"
File "caml_startup", line 1, characters 0-1:
Error: Error during linking

C:\Users\Jon\Documents\OCaml>ocamlopt test.ml -o test
** Fatal error: Cannot find file "C:\\Program Files\\Objective
Caml\\bin\\flexdl
l_msvc.obj"
File "caml_startup", line 1, characters 0-1:
Error: Error during linking

C:\Users\Jon\Documents\OCaml>ocamlopt test.ml -o test
'flexlink' is not recognized as an internal or external command,
operable program or batch file.
File "caml_startup", line 1, characters 0-1:
Error: Error during linking

What's the easiest way to get a working OCaml install under Windows ATM?

I used to build Ocaml from sources on Windows (it's pretty
straight-forward, just follow readme.win32 from Ocaml source
distribution). As for the errors:

Looks like you have installed the port based on the MinGW toolchain
(instead of MSVC one). Take the right one from
http://caml.inria.fr/download.en.html

Ocaml on Windows requires Alain Frisch's FlexDLL package. Grab it from
http://alain.frisch.fr/flexdll.html

FlexDLL is missing.

Again, I would recommend to build from sources.

It's easier to explicitly specify a path to MinGW libraries by passing
-cclib "-L c:/mingw/lib" to ocamlopt :-)

Only if one need the latest version of OCaml. If 3.11 is enough it's more convenient
to take a self installer.

  It's _really_ easier to use the overbld, which already adds this path
(and not only the MinGW path, but other patches and paths too, and
it already provides comfortable enough development environment,
and it WORKS now.).

  And, sorry, but I have no one to tell this but you...
