OVERVIEW:
|
|
|
|
OCaml is an implementation of the ML language, based on the Caml Light
|
|
dialect extended with a complete class-based object system and a
|
|
powerful module system in the style of Standard ML.
|
|
|
|
OCaml comprises two compilers. One generates bytecode which is then
|
|
interpreted by a C program. This compiler runs quickly, generates
|
|
compact code with moderate memory requirements, and is portable to
|
|
essentially any 32 or 64 bit Unix platform. Performance of generated
|
|
programs is quite good for a bytecoded implementation. This compiler
|
|
can be used either as a standalone, batch-oriented compiler that
|
|
produces standalone programs, or as an interactive, toplevel-based
|
|
system.
|
|
|
|
The other compiler generates high-performance native code for a number
|
|
of processors. Compilation takes longer and generates bigger code, but
|
|
the generated programs deliver excellent performance, while retaining
|
|
the moderate memory requirements of the bytecode compiler. The
|
|
native-code compiler currently runs on the following platforms:
|
|
|
|
Tier 1 (actively used and maintained by the core Caml team):
|
|
|
|
AMD64 (Opteron) Linux, MacOS X, MS Windows
|
|
IA32 (Pentium) Linux, FreeBSD, MacOS X, MS Windows
|
|
PowerPC Linux, MacOS X
|
|
ARM Linux
|
|
|
|
Tier 2 (maintained when possible, with help from users):
|
|
|
|
AMD64 FreeBSD, OpenBSD
|
|
IA32 (Pentium) NetBSD, OpenBSD, Solaris 9
|
|
PowerPC NetBSD
|
|
SPARC Solaris, Linux, NetBSD
|
|
|
|
Other operating systems for the processors above have not been tested,
|
|
but the compiler may work under other operating systems with little work.
|
|
|
|
Before the introduction of objects, OCaml was known as Caml Special
|
|
Light. OCaml is almost upwards compatible with Caml Special Light,
|
|
except for a few additional reserved keywords that have forced some
|
|
renaming of standard library functions.

DOCUMENTATION:
|
|
|
|
The OCaml manual is distributed in HTML, PDF, Postscript, DVI, and
|
|
Emacs Info files. It is available on the World Wide Web, at
|
|
|
|
http://caml.inria.fr/

|
AVAILABILITY:
|
|
|
|
The complete OCaml distribution can be accessed at

|
|
|
KEEPING IN TOUCH WITH THE CAML COMMUNITY:
|
|
|
|
There exists a mailing list of users of the Caml implementations
|
|
developed at INRIA. The purpose of this list is to share
|
|
experience, exchange ideas (and even code), and report on applications
|
|
of the Caml language. Messages can be written in English or in
|
|
French. The list has more than 1000 subscribers.
|
|
|
|
Messages to the list should be sent to:
|
|
|
|
caml-list@inria.fr
|
|
|
|
You can subscribe to this list via the Web interface at
|
|
|
|
https://sympa-roc.inria.fr/wws/info/caml-list
|
|
|
|
Archives of the list are available on the Web site above.
|
|
|
|
The Usenet news groups comp.lang.ml and comp.lang.functional
|
|
also contains discussions about the ML family of programming languages,
|
|
including Caml.
|
|
|
|
BUG REPORTS AND USER FEEDBACK:
|
|
|
|
Please report bugs using the Web interface to the bug-tracking system
|
|
at http://caml.inria.fr/bin/caml-bugs
|
|
|
|
To be effective, bug reports should include a complete program
|
|
(preferably small) that exhibits the unexpected behavior, and the
|
|
configuration you are using (machine type, etc).
|
|
|
|
You can also contact the implementors directly at caml@inria.fr.
