ocamlbuild: change the target name

ocamlbuild: change the target name

[Paolo Donadeo]

I'm porting the build system of Ex-nunc from a plethora of makefiles
to ocamlbuild.

Is it possible to change the name of the generated (bytecode or
native) executable name? The Ex-nunc page compiler has a main module
contained in the file (try to guess) mail.ml. Using:

$ ocamlbuild ...some options... main.byte

the program is correctly compiled and named main.byte, but I would
prefer the output was called "xnuncc".

Now I use the mv command, but it's not the best solution.


TIA,

There is many ways to do this kind of things.

1/  Rename your main.ml into xnuncc.ml and then accept to keep xnuncc.byte and
xnuncc.native names.

2/  Add  a  rule  to  myocamlbuild.ml  to  say  that  on can build xnuncc from
main.byte and that's just a copy.

...
copy_rule "The xnuncc binary" "main.byte" "xnuncc";;
...

The  problem  with this method is that the xnuncc file only live in the _build
directory. You have to manually copy it to install it.

3/  Use a script around ocamlbuild that make a link or a copy for you.

It's  mainly  a  matter  of installing things with ocamlbuild, that is a point
not really treated for now.

I think that is right. It is not ocamlbuild's job to install things.
