build fails on Ubuntu 16.04

[peschue]

I tried to build on Ubuntu 16.04 but the build fails.

ocamlbuild -no-links -use-ocamlfind -tag annot factoriojs.byte
Failure: ocamlfind not found on path, but -no-ocamlfind not used.
Compilation unsuccessful after building 0 targets (0 cached) in 00:00:00.
Makefile:36: recipe for target '_build/factoriojs.byte' failed
make: *** [_build/factoriojs.byte] Error 2

ocamlfind does not exist. ocaml is the one from Ubuntu installed as specified in the readme. It is version 4.02.3 - is this the problem?

If I edit the Makefile and use -no-ocamlfind instead of -use-ocamlfind I get the following errors:

ocamlbuild -no-links -no-ocamlfind -tag annot factoriojs.byte

I found out that I need to install a few more packages on Ubuntu 16.04 and then make works:

sudo apt-get install ocaml-findlib camlp4

reopening - maybe this could be added to the readme.

Thanks for the report! I'll indeed update the README. I use opam instead of the Debian packages so I did not notice this issue, sorry!

Fixed!
