Unfortunately I don't know enough about `oasis` to understand that bug<= br> report :(

I'll try to explain how I'd like to use oasis/buildtool by looking = how
Haskell's Cabal lets me do it:

- Configure without generating anything in the current dir:

=C2=A0 =C2=A0 % runhaskell Setup.hs --builddir /tmp/my_build_dir

- Build using the just generated configuration, again without putting
=C2=A0 anything in the current dir:

=C2=A0 =C2=A0 % runhaskell Setup.hs --builddir /tmp/my_build_dir

Comparing this to oasis/buildtool (assuming I've a pre-existing
`setup.ml<= /a>` generated with `oasis setup -setup-update dynamic` to
minimize the amount of build-related stuff in the project):

- Configure

=C2=A0 =C2=A0 % ocaml setup.ml -configure

=C2=A0 This generates a file, `setup.data` in the current dir.=C2=A0 I'= ve found no
=C2=A0 way to have it generated in a dedicated build dir.

- Build

=C2=A0 =C2=A0 % ocaml setup.ml -build -build-dir /tmp/my_build_dir -no-links

=C2=A0 This builds in the mentioned dir, but it also generates a `setup.log= `
=C2=A0 in the current dir!

I thought that `-C` could offer a way to achieve this, but it doesn't:<= br>
=C2=A0 =C2=A0 % mkdir /tmp/my_build_dir; cd /tmp/my_build_dir
=C2=A0 =C2=A0 % ocaml /path/to/setup.ml -h
=C2=A0 =C2=A0 Exception: Sys_error "_oasis: No such file or directory&= quot;.
=C2=A0 =C2=A0 File "/path/to/setup.ml", line 1:
=C2=A0 =C2=A0 Error: Reference to undefined global `OASISDynRun'

I'm not convinced `-C` *should* be the way to achieve what I want.

Hopefully this makes it clearer what I mean.


First, why not just copy everything in= the new directory:
% cp -R . /tmp/my_build_dir; cd /tmp/my_build_dir<= br>
% ocaml setup.ml=C2=A0-configure=C2=A0=C2=A0
=
% ocaml setup.ml -build

=
Maybe I miss some context to understand why this simple solution= is not enough.

Going back at the other points. Th= ere are 3 categories of files:
- the ones that are really generat= ed at build time: setup.log, setup.data
=C2=A0 -> they probabl= y need to follow the indication provided -C. This is a bug
- the = ones that are generated by the underlying build system: _build (ocamlbuild)=
=C2=A0 -> as you wrote "-build -build-dir /tmp/my_build_= dir -no-links" should be enough
- the ones that are generate= d by the dynamic mode, which is a hack to prevent adding the files that oth= er tools need:
=C2=A0 -> these ones are tricky because they sh= ould have been in the source directory right from the beginning and being a= ble to apply -C to them is equivalent to make sure that "ocamlfind&quo= t;/"ocamlbuild"/other build tools will use -C and the source dire= ctory... This is clearly not trivial to assume that all tools will do.

My initial proposal to "cp" the files and bu= ild from the copy would probably solve your problem without assuming that a= ll tools comply with -C. Tell me if it solves your problem.
