[Caml-list] Ocamlfind can’t find lexer in default folder compiler-libs

Hi all, I’m trying to revive and modernise the project iocamljs by Andrew
Ray. Here’s my fork branch:
https://github.com/vietlq/iocamljs/tree/scratch/modernise-build

I was able to compile initially but somehow it stopped compiling. The issue
is ocamlfind can’t find lexer in default folder compiler-libs. I’m using
macos Mojavee and OCaml 4.06.1.

The steps to reproduce:

git clone https://github.com/vietlq/iocamljs.gitcd iocamljs
git fetch --all
git checkout scratch/modernise-build

make clean full

The error logs:

rm -f *.cmis.js
rm -f *.cm[ioa] iocaml_full.byte iocaml.byte iocaml.js
rm -fr *~
ocamlfind ocamlc -c exec.mli
ocamlfind ocamlc -package lexer -package js_of_ocaml -package js_of_ocaml-ppx \
		-package str,dynlink,js_of_ocaml,js_of_ocaml.compiler,js_of_ocaml.toplevel \
		-I /Users/vietlq/.opam/4.06.1/lib/ocaml/compiler-libs \
		exec.ml
ocamlfind: Package `lexer' not found
make: *** [exec.cmo] Error 2

I actually have lexer files by default:

$ ls -ltra $HOME/.opam/4.06.1/lib/ocaml/compiler-libs/*lexer*

$HOME/.opam/4.06.1/lib/ocaml/compiler-libs/lexer.cmi
$HOME/.opam/4.06.1/lib/ocaml/compiler-libs/lexer.cmt
$HOME/.opam/4.06.1/lib/ocaml/compiler-libs/lexer.cmti
$HOME/.opam/4.06.1/lib/ocaml/compiler-libs/lexer.mli
$HOME/.opam/4.06.1/lib/ocaml/compiler-libs/lexer.cmx

Any help is appreciated.

Hi Viet,

Probably you should use `-package compiler-libs.common` instead of
`-package lexer` (and if you do this you should not need to explicitly
pass the path to the compiler-libs directory with `-I`).

Hope it helps!

Best wishes,
Nicolás

Hi Nicolás,

Thanks for your reply. I tried compiler-libs.common and compiler-libs and
got another issue:

Error: Required module `Lexer' is unavailable

So it means both compiler-libs and compiler-libs.commons do not contain the
module Lexer.

Thanks,
Viet
