Dear caml-list members,

I'm trying to install CIL in the following environment, but it failed.
I need CIL to analyze source.
Does anyone give me a solution?

OS: ubuntu 14.04
$ opam --version
$ 1.2.2
$ ocaml -version
$ The OCaml toplevel, version 4.02.3

I only did:
1. Install ubuntu
2. $ sudo add-apt-repository ppa:avsm/ppa
3. $ sudo apt-get update
4. $ sudo apt-get install ocaml ocaml-native-compilers camlp4-extra opam m4
5. $ opam init
6. $ opam switch 3.11.2
(cil needs ocaml 3.xx.x)
7. $ eval `opam config env`
8. $ opam install CIL

And we get :

The following actions will be performed:
  ∗  install ocamlbuild 0                     [required by cil]
  ∗  install ocamlfind  1.5.3                 [required by cil]
  ∗  install cil        1.7.3
===== ∗  3 =====
Do you want to continue ? [Y/n] y

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.
