I used to use http://protz.github.io/ocaml-installer/ which generates native standalone binaries which can run under CMD or powershell.
After upgrade to 4.06, there is no such installer any more, I tried to install from source, everything works except that generated exe can only run under cygwin since it require cygwin1.dll? Is there any way to generate exes under Windows without dependency on cygwin?
Thanks
Since you compiled from source, you certainly read the release notes for the Microsoft Windows ports of OCaml (https://github.com/ocaml/ocaml/blob/trunk/README.win32.adoc)?
Do not confuse the environment used to compile them with the different ports. By instance, you can compile the Native Mingw-w64 port from within cygwin, whithout restrictions on the generated executables.
[I replied by email, but one sentence is missing. Iâm manually adding it here:] From my own experience, I would recommend to use the excellent âOcaml for windowsâ (https://fdopen.github.io/opam-repository-mingw/).
Best regards
To generate native Windows binaries (that do not depend on the Cygwin DLL) you have two options, depending which toolchain you want to use:
- use the native Microsoft toolchain (compiler: cl)
- use the mingw-w64 toolchain (compiler: gcc)
To use 1., configure as follows:
./configure --build=x86_64-unknown-cygwin --host=x86_64-pc-windows
To use 2.:
./configure --build=x86_64-unknown-cygwin --host=x86_64-w64-mingw32
(with some variations if you want output 32 bit binaries). Full details at https://github.com/ocaml/ocaml/blob/trunk/README.win32.adoc

I get an errror after set --host option, --build option does not work.

I remember we used to have a binary distribution on Windows platform for casual users, now it seems to get even more difficult to try ocaml on windowsâŚ
I tried the GUI installer provided by fdopen, it failed in the last step. Its version is 4.07 though
The instructions given in my previous reply are for 4.08; for previous versions you need to do:
cp config/m-nt.h byterun/caml/m.h
cp config/s-nt.h byterun/caml/s.h
-
for microsoft toolchain (cl)
cp config/Makefile.msvc64 config/Makefile -
for mingw toolchain (gcc)
cp config/Makefile.mingw64 config/Makefile
and then compile with make world.opt. Note that you need a working development environment for this to work (the compiler needs to be in your path, etc.)
Again all of this is documented in the README.win32.adoc file.

This makes a bit further, but now I have such an error:

You are missing an installed flexlink. The easiest way to get it is to do make flexdll before make world.opt.
NOTE: you will need to completely clean your tree before doing make flexdll (ie git clean -fdx if using a git clone).
try to make flexdll, thanks for the help

Are you starting from a clean tree? It worked just now for me. I did:
$ curl -L -O https://github.com/ocaml/ocaml/archive/4.06.1.tar.gz
$ cd ocaml-4.06.1
$ cp config/m-nt.h byterun/caml/m.h
$ cp config/s-nt.h byterun/caml/s.h
$ cp config/Makefile.mingw64 config/Makefile
$ git clone https://github.com/alainfrisch/flexdll.git
$ make flexdll world.opt

Actually not. I get another error while using the installed ocamlopt.

Try adding /cygdrive/c/ocamlmgw64/bin to your PATH. Does it solve the issue?
Yes, now it works, thanks a ton!
Another take away is make sure to have OCAMLLIB unset if you have other ocaml installations

Not sure which part is screwed, retried the command line again, get such failure:

Maybe itâs better to try newer version then? 4.09 was released sinceâŚ
