ocamlbuild - how to force the rebuilding of a target inside a plugin?

[Vincent Aravantinos]

Hi list,

does anybody (Nicolas?) knows if it is possible to force a target to  
be rebuilt from within an ocamlbuild plugin?

Concretely I am making a plugin for LaTeX compilation and would like  
to say to ocamlbuild:
"first compile the source, then if the .aux file has changed then  
recompile it".

I would suggest to not try to bypass the dependency system and to instead
try to make a rule that fits ocamlbuild mechanism. However the simpler
is maybe to call a tool which does this job like rubber.

Great, I didn't know of this tool! I'll use it.

Still, would have it been possible to make a dependency on the .aux  
file such that ocamlbuild can be aware that this file changed in order  
to launch a new compilation?

No there is no such behavior, but this may be simulated by having two rules,
one .tex->.aux+... and one .tex+.aux->... and putting them in the right order
might work.
