[Caml-list] OCaml support on Ubuntu
Hello Richard, Context: I'm a long time Debian user, still using Debian on my servers. But I switched my desktop machine under Ubuntu a few years ago, seduced by the good polish and freshness of Ubuntu desktop applications. Richard Jones [EMAIL PROTECTED] writes: Ubuntu's OCaml support is very flaky. They don't have developers committed to it and take a random snapshot of what's in Debian. This has in the past led to serious brokenness where they've taken a snaphot in the middle of a rebuild-the-world compiler upgrade. I'm sorry to agree that Richard is right. For example, I discovered at a time that *all* bytecodes shipped in Ubuntu Gutsy could not be executed. This was fixed once spotted: https://bugs.launchpad.net/ubuntu/+source/ocamlnet/+bug/180364 Another example: current Hardy release (which has Long Term Support status) is shipped which OCaml 3.10.0 which is broken regarding Camlp4. To fix this situation, one only needs people on the Ubuntu side to synchronize packets from Debian at the right time. As I have an direct interest in this story and while I have no knowledge at all regarding Ubuntu workflow, I'll try to see what can be done.

Well I'm not an official Ubuntu developer, just someone who develops on Ubuntu, but I have joined the Debian Ocaml Maintainers mailing list and I'm even thinking of becoming an official Debian maintainer. That's great, and thanks for your help! However, it was not only what I meant. Surely we, Debian-side, have a lot of work to be done and help is always needed. Still, we need someone Ubuntu-side which coordinate with us for their releases. We are doing an excellent job in sharing patches with Fedora (thanks mainly to Richard of course), it's kind of astonishing that we cannot coordinate with Ubuntu. The main reason is of course that there is currently no Ubuntu OCaml Maintainers group or something similar, would you like to start organizing one? If you, or anybody else, is an Ubuntu user willing to help in OCaml package maintenance let me know, there is for sure a task for you :-) Sure. Whats up? You can start looking up all the bug reports against packages maintained by [EMAIL PROTECTED], or other individual maintainers of OCaml-related packages. Moreover, we have several pieces of great OCaml softwares which are not packages while they should. We also have some infrastructure pieces missing, if you are following the mailing list I'm sure you are aware of some of them.

The needed steps IMO are: 0) identify who among the Ubuntu developers (core developers or MOTU, I don't care) is willing to maintain OCaml-related stuff 1) decide upon a collaboration infrastructure and use it for *both* Debian and Ubuntu My proposal on this is of course to reuse Debian's, as we already have a version control system and a mailing list, and we have already reached a critical mass. By experience, other mixed Debian/Ubuntu maintenance teams are using the Debian infrastructure and is working quite well for all of the involved people 2) coordinate releases, so that the OCaml toolchain is in shape when either of the distribution makes a release 3) total world domination AFAIK we are still missing step 0. -- Stefano Zacchiroli -*- PhD in Computer Science \ PostDoc @ Univ.

[Caml-list] embedding ocaml into a windows app: need gcc?
Can I do without gcc if I want to embed the OCaml compiler into a commercial Windows app? Do I need to become part of the OCaml consortium to do this?

The OCaml compiler uses gcc in various stages (linking IIRC). Also needs an assembler. Do I need to become part of the OCaml consortium to do this? You certainly need to read the license very carefully. However is it necessary to embed the compiler? Can you not just call out to the compiler as a separate process? It's surely easier to do Sys.command, rather than working out the licensing and technical issues involved in linking your program to the compiler. Ideally, I would like to generate OCaml code at runtime and compile it into something that can be loaded by a runtime of some sort. Compiling into a DLL would be ideal, is it possible? ocamlopt -fPIC ... should be able to do it. Or compile the code with ocamlc and use Dynlink.

Re: [Caml-list] embedding ocaml into a windows app: need gcc?
I don't know if this answers your question, but OCaml 3 now has Dynlink, i.e. a manner of dynamically loading OCaml modules from OCaml. So if you manage to get your code compiled at run-time, it shouldn't be too hard to load it.

Re: [Caml-list] embedding ocaml into a windows app: need gcc?
2008/9/27 Joel Reymont [EMAIL PROTECTED]: Can I do without gcc if I want to embed the OCaml compiler into a commercial Windows app? I assume you mean native compilation. As mentioned, you should consider using a standalone ocaml compiler to avoid licensing issues, but either way: The ocamlopt compiler generates assembly source code and doesn't need a C compiler. It needs a runtime library, a linker and an assembler. On Windows you need to install masm - or find a compatible alternative. (On Unix I think gcc works as assembler). Masm can be downloaded without too much trouble - but if you start deploying it to other users, you may have a problem. Likewise, you must consider if your users have a linker installed and how you can distribute it legally. So assuming you have an assembler, ocaml compiler, linker and ocaml libraries: If you want to attach the generated code to a live process, you need to create a dll or a new process. If you want to attach to existing code then start a process, you can use static linking. So lets assume you want to create a dll. On Windows you don't need to compile position independent code, last time I looked, so -fPIC is not relevant. You compile an ocaml library and link it with other code as a dll. With the next ocaml version you might even be able to create a dll and use it not from OCaml but from any other program. Then the problem is solved - except for installing all the compile tools. Without the above solution, I have created such dll's some years back. More specifically to embed an ocamlyacc compiler in other Windows programs. You need to get the compile flags right, but it definitely is possible. You can also create a COM dll if you want - and call it from .Net. The benefit of a COM dll is that you get a clear calling interface and can interface with .NET easily. The downside is that COM projects are ugly. If you create a simple dll, you need a way to manage your call backs. I have an old ocamldll library for this purpose. It lets you register multiple ocaml function names in a dll and call them from the application by name. The new windows dll solution scheduled for next OCaml version has a more elegant solution where you don't have to register callbacks: http://alain.frisch.fr/natdynlink.html You can probably use this even with current OCaml version since it is Windows specific, not OCaml specific. Let me know if I should publish my ocamldll thing which will work, but is not cutting edge. All that being said: I have considered the same thing, and it is messy because of the compiler tools. I would like an OCaml support library that can compile and execute similar to JaveScript engines, but we don't have that in any practical form. So I would recommend looking into embedding a javascript compiler instead if performance is not absolutely critical - you could still drive fast ocaml library routines. In the past few months performance has exploded both in WebKit and Mozilla. Google has also released a fast engine named V8. WebKit has LGPL licensing issues, but Mozilla and V8 should be very embeddable. All compilers have JIT compilation, Mozilla also 64-bit. Or look at Haxe or Lua.
