If it's for Unix, then just open a pipe to or from an external compression filter, eg: open Unix open Printf let () = let output = "output.xz" in let chan = open_process_out (sprintf "xz --best > %s" (Filename.quote output)) in output_value chan 42; let status = close_process_out chan in (* some code here to check status was ok *) () (Also a good way to generate images from OCaml programs: pipe to pnmto* programs).Adrien Nader also replied:
There are libarchive bindings by Sylvain Le Gall on the forge too. They're partial but already work for reading iirc, and writing shouldn't be a lot of work (if it hasn't been added since I last looked at it). That will potentially give xz, gzip, bzip2, tar, cpio and I don't know what else.

It is my pleasure to announce the multitude of (long overdue) releases tonight : ocaml-extunix 0.0.4 ------------------- ExtUnix provides thin bindings to various low-level system APIs which are not covered by Unix module. This release adds many new bindings and implements bigarray variants of some functions (as a consequence extunix now depends on bigarray). Many thanks to Goswin von Brederlow (who was the driving force behind this release), Andre Nathan and all previous (and future) contributors. Get it at http://extunix.forge.ocamlcore.org/ ocaml-mysql 1.1.1 ----------------- Bindings to libmysqlclient. This release update build infrastructure tools (OCamlMakefile, autotools, etc), provides Windows build support (both for msvc and mingw), fixes OCaml 3.12 compatibility and implements a couple of new features. Thanks go to Dmitry Grebeniuk and Hezekiah M. Carty. More info and download links : http://ocaml-mysql.forge.ocamlcore.org/ ocaml-geoip 0.0.1 ----------------- Bindings to libGeoIP library to access offline database of geographical information keyed by IP address. The bindings code is generated by camlidl and hopefully provides a comprehensive coverage of available C API. Homepage : http://geoip.forge.ocamlcore.org/ ocaml-lzo 0.0.1, ocaml-snappy 0.0.1 ----------------------------------- Both these packages implement bindings to fast lossless compression/decompression libraries (that generally favor speed over compression ratio) and feature simple interface that operates on string buffers. Choose your poison : http://snappy.forge.ocamlcore.org/ or http://lzo.forge.ocamlcore.org/ ocaml-winsvc 0.0.1 ------------------ winsvc helps to turn OCaml program into Windows service. This is some old (but working) code with hardcoded build scripts. Drags out miserable existence at http://winsvc.forge.ocamlcore.org/
Thanks to Alp Mestan, we now include in the Caml Weekly News the links to the recent posts from the ocamlcore planet blog at http://planet.ocamlcore.org/.
