Makefile:102: recipe for target 'ocamlbuild' failed

[blank-black]

Hi, when I tried to install the cil in my ubuntu 18.04.4 TLS, I found some problems.

• First, I tried to use
  opam install cil
  to install cil but it shows
  [ERROR] cil is not a valid versioned package name
'opam install cil' failed.

• After that, I tried opam install cil.1.7.3 but it still couldn't work.
  [ERROR] "cil" is not a valid package.
'opam install cil.1.7.3' failed.

• Then I tried to use the project to make it.
  But after I run ./configure successfully, when I run make, some error occured.
