But i am looking for something included in it ( think that in your very large project, you have a library that builds against an external one, i want that the makefile system detect it and output that it needs this library... ). > > if $(not $(equal $(OSTYPE), Win32)) > OMakefile: OMakefile.in config.status > @echo "*** Build system is out-of-date, rebuilding ***" > $(DOT)config.status > @echo "*** OMakefile was rebuilt, session should restart ***" In fact i want to get rid of it ( no $(DOT)config.status ). Autools et al are very well made but i think that it is too much complicated ( having try to understand how it is build but most of the time i really can t get into it ). > > >Can you use META files. > > Not sure what those are. > META file comes with findlib. Findlib is an helper to configure ocaml compilation : ocamlfind ocamlc -package "fileutils" xxx.ml will run ocamlc -I /usr/lib/ocaml/fileutils ... Gerd Stolpmann write it ( www.ocaml-programming.de ). Sorry to the author if i mistyped his name... I take a quick glance to you OMakefile... Well i think it is very powerfull and very interesting... But ( there is always a but ), i am looking for something between your very complete suite and ocamake which is light and permits to do fast job for ocaml stuff. I know, i will run into problem if not targeting all people... But, i cannot choose all options. I want something enough powerfull to build little to medium ocaml project -- with some C binding. I don't want to rebuild make. The ideal project ( in size ) will be cameleon ( fully written in ocaml ) or mldonkey ( mostly ocaml with some C ). I don't really want to be able to compile C, python, Ada... I want to use some kind of ocaml script ( let say makefile.ml which will contain the instruction to build, explains the dependency etc ) to enable user to be fully consistent with their project ( they learn ocaml and not makefile syntax ). I think it should be necessary to have a plugin system ( through dynlink or topfind, don't know yet ) to enable them to develop their own set of rules ( if they want to compile specific things ). What i have read in you omakefile is a kind of full rewrite of make ( ie you have construct of function, dependency etc ). I precisely don't want to develop my own langage for this purpose, i want to have it written in ocaml. Just to give you an example, all the student i know have problem using makefile because they don't want to spend two hours understanding this big script... So they simply don't use it... How many times i have seen one-file-project without makefile, or people using "ocamlc X.ml && ocamlc Y.ml && ocamlc Z.ml..." I want ( just as i have posted before ) : let my_prog = { name = "my_prog";...;toplevels = [ "X.ml" ] } in add_target my_prog and that's all. And i want to be able to do it on linux or win without being needed to do if Win32 then ... else ... ( every time you write if ... else ..., it is a possible infinite source of error ). I will have a deeper look to your omakefile ( understanding how it is working, if i can learn from the rules to target process ... ). thanks for having helped me to find more project similar to mine. Kind regard Sylvain LE GALL ps : i cannot find your project omakefile on humps pps : if you have time you could take a look at cameleon CVS, branch findlib : http://savannah.nongnu.org/projects/cameleon, there is a bunc of ten lines makefile which are sufficient to define what to compile for each directory... That is the mininum sums of information i want user to give to have a fully working makefile system ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
