The OCaml Installer for Windows
These are the source files if you want to rebuild the installer. If you just want to download the installer, see the "website" link near the top of the page.
The installer now uses the "official" toolchain, namely Mingw64 living in a Cygwin environment. The current version of this installer works with OCaml 4.0; if you want to compile an older version of OCaml, you need to switch to and older revision.
- Cygwin with the mingw64 compiler suite, 32bit version (i686-w64-mingw32).
- FlexDLL (at least 0.29)
- NSIS (the special build that uses 8k strings)
- the NSISunz plugin for NSIS, that lives somewhere on the NSIS wiki
Instructions for building an new version of the installer
The instructions above sometimes use the
c:\...-style paths, sometimes the
/c/...-style paths. This is significant, and you cannot blindly replace one
- Install FlexDLL from Alain's website, and
- Refresh the files in the
flexlink/directory of the installer, so that the resulting installer ships the right version of flexdll (optional, recommended).
- Grab a copy of ActiveTCL and install it, leave the default path (
c:\tcl). Make sure the URL in
- Grab a copy of the OCaml sources, and keep the default install path
c:\ocamlmgw), this will make your life easier.
- Follow the instructions in
README.Win32, section "MinGW/Cygwin". Try to compile OCaml. Swear. Try again. Grab a tea. Succeed. Be happy.
- Go into the
- Make sure there's an
emacs.exein your path (install Emacs if you have to).
- Configure the Makefile so that the output directory is
makein that directory.
- Make sure there's an
- Checkout a copy of OCamlWin from the OCaml forge, edit Makefile.local and
make && make install.
- Make sure
/cygdrive/c/ocamlmgw/binis in your path.
- Grab the latest findlib,
make all opt,
- Check that install.nsi will generate a correct
- Copy findlib's
topfindin the OCaml Installer directory.
- Install NSIS, grab
nsisunz.dllsomewhere on the interwebs and put it NSIS's
- In the
ocaml-installerdirectory (i.e. this repo), run
make. This should create a variety of files:
version.nsh, a NSIS header file that is generated to contain the freshly compiled OCaml's version number,
uninstall_lines.nsi, an OCaml-generated list of files to remove from the install directory.
- Make should also launch NSIS with the main script file, and hopefully it should all generate an installer. The installer is quite big (thank you camlp4).
