This is how dependency scanners also work. You can see an example in http://git.dvide.com/pub/ocamlbuild-ctools/tree/myocamlbuild_config.ml search for: accumulated_include_rule Here accumulated_include_rule is used instead of rule, but it calls rule eventually, but with its calculated prod arguments that it gets (in this case) from reading multiple dependency files. You could modify this function to take a list of a .tgz file. Some care needs to be taken since each build step must produce an actual file - especially when creating dependencies, but it is not necessarily required in you case. Dependency scanners do need to produce files so something else can depend on this files to ensure the dependency is scanned. Mikkel ___ Caml-list mailing list.

Would it be possible to write a function to read these files in to a list then use "dep [foo; bar] file_list;"? This is what I use for included files in .idl files. I have only done this with static, pre-defined lists using 'dep ["compile"; "camlidl"] ["file1.inc; file2.inc"];'. I'm not sure how well it would work or if it would work at all with a dynamic list of files. Hez -- Hezekiah M.

I've used the following rule under After_rules in myocamlbuild.ml for camlidl .idl files: (* Handle *.idl files properly... I think *) rule "camlidl processing" ~prods:["%.mli"; "%.ml"; "%_stubs.c"] ~deps:["%.idl"] begin fun env _build -> let idl = env "%.idl" in let tags = tags_of_pathname idl++"compile"++"camlidl" in let cmd = Cmd(S[camlidl; T tags; P idl]) in Seq [cmd] end; Then, given foo.idl, "ocamlbuild foo.cma" seems to work properly, finding the relevant camlidl-output files. Hope this helps. Hez -- Hezekiah M. Carty Graduate Research Assistant University of Maryland Department of Atmospheric and Oceanic Science ___ Caml-list mailing list.
