[Caml-list] Compiling a 32 bits version of OCaml with godi and OS X.6 ? (pcre problem)
Hello, I'm trying to build a 32 bits version of ocaml, so I added this to my godi.conf OCAML_CONF_ARGS=-cc gcc -m32 -as as -arch i386 -aspp gcc -m32 -c The problem is that PCRE is built by default in 64 bits. Is there a similar environment variable that I can change to specify the target architecture? Thanks, Alan ___ Caml-list mailing list.

I believe you can compile Lwt without the ocaml-ssl library by just removing file src/lwt_ssl.mllib OK. I wanted to install it through godi, but I guess it will be simpler to compile it directly. (The ideal would be a configuration option to have ssl as optional.) In file src/lwt_unix.ml, you should also change the line: let windows_hack = Sys.os_type Unix into let windows_hack = false This was a hack to make Unison work properly under Windows even though select did not support pipes. As the implementation of select has been improved in Ocaml 3.11, it should no longer be necessary. Very interesting, I was not aware of this.

[Caml-list] options to write a cross-platform interacting program in OCaml
Hello, I am looking at what options there are to rewrite camlgrenouille, a small client for www.grenouille.com that I wrote a while ago, to make it more modular (to allow an external UI to the core program) and cross-platform (Unix and Windows). In a nutshell, this program periodically runs some tests. Right now its interaction with the outside is fairly limited: the only thing one can do is ask it to quit (by doing a ctrl-c which is caught so as to clean up before actually quitting). I would like to be able to send it more complex commands, which would be driven by a UI separate from the program. The simplest approach seems to be using a socket and a select call (with a timeout corresponding to the delay until the next test), but I was wondering if there were other options based on threads. For instance, could I use lwt under Windows? Thanks for any suggestion, Alan PGP.sig Description: This is a digitally signed message part ___ Caml-list mailing list.

[Caml-list] Computing with big numbers?
Hello, In preparation for a talk I'm going to give, I wanted to estimate how good 128 bits MD5 hashes were: how many hashes must be taken before the probability for a collision become non negligible? (I'm assuming equi-probability of every hash.) The brute force approach is simply to enumerate the non-collision probability for k different hashes, and compute until it becomes lower than 1. This probability is (writing N for 2 ^ 128): N * (N-1) * (N - 2) * ... * (N - k) --- N^k I tried computing this using the bignum library that comes with OCaml, and it slows down to a crawl very fast (for k ~ 1000). So I tried to be more subtle and approximate the result (using Stirling's approximation of factorials), but OCaml's floats are not precise enough to yield anything significant. (I'm trying to compute the log of the approximation of N! / (N^k * (N-k)!), which is N (ln N) - N - (k (ln N) + (N - k)(ln (N - k)) - (N - k)).) Is there a library with better floating point precision than the OCaml one? Thanks, Alan PGP.sig Description: This is a digitally signed message part ___ Caml-list mailing list.

[Caml-list] JFLA 2009: dernier appel aux communications
(This message is intentionally written in French) * MERCI DE FAIRE CIRCULER * MERCI DE FAIRE CIRCULER * MERCI DE FAIRE CIRCULER * DERNIER APPEL AUX COMMUNICATIONS DERNIER APPEL AUX COMMUNICATIONS JFLA'2009 (http://jfla.inria.fr/) Journées Francophones des Langages Applicatifs Organisées par l'INRIA 31 janvier au 3 février 2009 JFLA'2009 est la vingtième conférence francophone organisée autour des langages applicatifs et des techniques de certification basées sur la démonstration. Ces nouvelles journées se tiendront du 31 janvier au 3 février 2009. Elles auront lieu à la montagne, à Saint-Quentin sur Isère, au pied du Vercors, à proximité de Grenoble. Toujours centrée sur l'approche fonctionnelle de la programmation, la conférence porte également sur les techniques et outils complémentaires qui élèvent le niveau de qualité des logiciels (systèmes d'aide à la preuve, réécriture, tests, démonstration automatique, vérification). Les JFLA réunissent concepteurs et utilisateurs dans un cadre agréable qui facilite la communication; ces journées ont pour ambition de couvrir le domaine des langages applicatifs au sens large, en y incluant les apports d'outils d'autres domaines qui permettent la construction de systèmes logiciels plus sûrs. L'enseignement de l'approche fonctionnelle du développement logiciel (spécification, sémantiques, programmation, compilation, certification) est également un sujet qui concerne au plus haut point les JFLA. C'est pourquoi des contributions sur les thèmes suivants sont particulièrement recherchées (liste non exclusive) : - Langages applicatifs : sémantique, compilation, optimisation, mesures, tests, extensions par d'autres paradigmes de programmation. - Spécification, prototypage, développements formels d'algorithmes. - Utilisation industrielle des langages applicatifs. - Assistants de preuve : implémentation, nouvelles tactiques, développements présentant un intérêt technique ou méthodologique. - Enseignement dans ses aspects liés à l'approche fonctionnelle du développement. Les JFLA cherchent avant tout des articles de recherche originaux qui apportent une réelle nouveauté. Toutefois, un article traitant d'un sujet qui intéresse plusieurs disciplines sera examiné avec soin, même s'il a préalablement été présenté à une autre communauté sans rapport avec celle des JFLA. Un article ayant été traduit en français à partir d'une publication récente en anglais sera examiné, à condition que la traduction apporte un élément nouveau. Les articles soumis aux JFLA sont relus par au moins 2 personnes s'ils sont acceptés, 3 personnes s'ils sont rejetés. Les critiques des relecteurs sont toujours bienveillantes et la plupart du temps encourageantes et constructives, même en cas de rejet. Il n'y a donc pas de raison de ne pas soumettre aux JFLA !

You might be referring to this message: http://thread.gmane.org/gmane.comp.lang.caml.general/38930 The cute trick consists in building a PPC version of OCaml on a PPC machine, and then copying it over to your Intel machine. It will run fine (albeit slowly) under Rosetta, and generate PPC executables. Ah, thank you, this seems to be it. Just one small additional question about this: where should I put the supporting libraries (the ocaml directory with libunix.a for instance), and how can I make sure the ppc version of ocamlopt find these libraries, and not the i386 ones?

On 19 mai 08, at 15:07, Alan Schmitt wrote: Hello, Is this (http://alan.petitepomme.net/cwn/2007.09.18.html#1) the recommended way to build a universal binary on OS X? (To summarize: use a PPC version of ocamlopt and use lipo to glue the binaries together.) I've realized I may not have given enough details as to what I want to do here, so here they are. My goal is to be able to compile the OS GUI version of Unison on a single machine. Right now, using my intel-based notebook, I'm able to compile a version that runs both on 10.4 and 10.5, but only on intel. (By the way, compiling ocaml to manage this was not obvious. Here is how to do it using godi, thanks to Gerd Stolpmann: - net the following in godi.conf OCAML_CONF_ARGS=-cc gcc -mmacosx-version-min=10.4 - rebuild godi-ocaml-src and godi-ocaml Then I can specify in Xcode that I'm targetting 10.4 as my minimum version, and I don't get any error when linking against the ocaml libraries.) The next step is to be able to build Universal Binaries versions of the ocaml libraries, so that I can tell Xcode to target both architectures. This implies that ocaml should be able to cross-compile to PPC, which I don't know if it can do. I think I remember an old message addressing this, but I have not been able to find it. If anyone could point me to the right direction, it would be very helpful. Thanks, Alan PGP.sig Description: This is a digitally signed message part ___ Caml-list mailing list.
