OCaml

Installation notes for MS-Windows

Since Windows comes with no development environment, there are quite a few packages to install.

OCaml: the toplevel and compilers. To have an entirely free framework, download the MinGW port.
Tck/Tk 8.4: not strictly needed but allows to run ocamlbrowser, so it is recommended.
flexdll is indispensable to compile programs to native code and to link to C libraries.
MinGW [use the “Download Now!” button] and the MSYS Base System provide essential tools compile C code and to drive build processes. During the installation MinGW, select g++ during installation. Note that, in order to find dllcrt2.dll, one must add -Lc:/MinGW/lib to various commands.
findlib: simplify and make more portable the compilation of libraries and programs thanks to the ocamlfind utility. Download the tarball or get the development version with
```
bzr branch https://godirepo.camlcity.org/svn/lib-findlib/trunk/ findlib
```
compile it with “./configure” followed by “make all opt”, and finally install it with “make install”.

Whichever editor you use, you should configure it so it adheres to the OCaml's programming guidelines.

Emacs is a very powerful editor that is well worth to learn. For OCaml, use the tuareg mode. If you were told Emacs lacks features that modern IDE have, check Emacs For Dev Studio Users.
For Vim, you can use the excellent configuration files by Markus Mottl.
If you like Eclipse (which is heavy but popular these days), we recommend the plugin OcaIDE.
For NEdit use the patterns written by Nathaniel Gray. Be aware however that NEdit does not support uft-8 and relies on the aging Motif toolkit.
For Kate, use the plugin by Matteo Franchin.
