Subject: Dynamic link libraries
let me introduce myself. I'm a newcomer to ML and to the world of
functional programming in general. I'm currently giving OCaml and
Moscow-ML a try. From OCaml I like the possibility of writing external C
functions, but I dislike the limits that it imposes, that is:
* One has to generate a custom runtime
* One has to link those libraries against the runtime.
I believe this breaks modularity. Isn't it possible to support the
* Creation of *shared* bytecode/native-code Caml libraries.
* Dynamic loading of those libraries, much like Moscow-ML does: a simple
'load "filename.uo"'. (Moscow-ML is based on Caml-Light -- thus I
believe this must be possible, somehow)
* Linked executables (either native/bytecode ones) that make use of
* Dynamick linking of native DLLs, that is, those which are generated by
the C compiler, such as libX11.so, etc. This is just a matter of 30
lines code in Linux and other unices which support the `dlopen'
* Exposure of the symbols loaded from a DLL, so that they are recognized
in "external" clauses.
This would lead to a better development evironment, and to some space
saving due to not having to produce custom runtimes. I will appreciate
any comment about why this hasn't been done already.
P.S: I don't know French, hence this single version message.
