Binary distribution

Ocsigen is available in some software distributions, e. g.:

• Debian (good support) and Ubuntu (Currently, only ocsigen 1.3.4 is available)
• Gentoo (Currently, only ocsigen 1.3.4 is available)

If your distribution has all the packages you need, this is probably the simplest way to install Ocsigen software.

Source compilation

If the latest version of Ocsigen is not available in your distribution or if you want to install a development version, you may compile the whole Ocsigen platform with one of the following techniques:

• The Ocsigen bundle ease the compilation of the Ocsigen platform and its OCaml library dependencies.
• The Godi source code distribution usually provides the latest Ocsigen releases.
• Downloads and compile each project individually.

Individual source package

The Ocsigen platform as a lot of dependencies, and building each project individually may be a long process. Here the consolidated list of dependencies in the order you may build them.

Build each projects separately

As this step, you may build the Ocsigen platform in this order:

• Lwt (enable at least ssl and react support)
• deriving-ocsigen
• Js_of_ocaml
• TyXML
• Ocsigen Server
• Eliom
