[Caml-list] ocamlbuild, build a source that starts with _

[Daniel Bünzli]

Hello,

It seems I can't convince ocamlbuild to build (i.e. copy) a source that starts with `_`. 
Is there a workaround ? 

  mkdir -p /tmp/test
  cd /tmp/test/
  touch _bla.c
  ocamlbuild _bla.c
  Solver failed:
  Ocamlbuild knows of no rules that apply to a target named _bla.c. This can happen if you    ask Ocamlbuild to build a target with the wrong extension (e.g. .opt instead of .native) or if the source files live in directories that have not been specified as include directories.
Compilation unsuccessful after building 0 targets (0 cached) in 00:00:00.

I guess this must be due to this line (though I have to admit that I have hard time to understand ocamlbuild's convoluted control flow).  

https://github.com/ocaml/ocamlbuild/blob/master/src/main.ml#L150

so the answer seems to be no, which is quite annoying.

Well, it is still possible to work around this issue by re-doing the
slurping from the plugin:


https://gitlab.com/gasche-snippets/ocamlbuild-underscored-files/blob/master/myocamlbuild.ml

I wouldn't mind removing that test from future ocamlbuild releases -- as of
now I don't see any problem with "_oasis" or other "_tags" file being
considered parts of the build tree.

Thanks for the snippet, but... I'll find another work around.

It's not only "_oasis" or "_tags" file it's *any* file that starts with a `_`, which is a bit dubious. I don't see any rationale behind this (and especially none behind ocamlbuild being made aware of _oasis files).  

Best,

Daniel
