Hi guys, new user here
I have an OCaml project that I’ve been working on for 3 years. It’s using
ocamlbuild
at the moment, and I decided to givedune
a whirl over the weekend. But having an issue with thedune build
command, where it seems like it’s not doing anything.The project is a command-line game, and has a very simple layout. Just three directories:
util
,game
,tty
util
is a(wrapped false)
library containing auxiliary modules used bygame
andtty
.
game
contains all the game logic, and is also a library.
tty
implementsgame
as a command-line application.tty/main.ml
is the entry point.So, I set up the dune files like this:
dune init lib util util
<-- Then added the(wrapped false)
bit manually.
dune init lib game game --libs util
dune init exec main tty --libs util,game
Now, when I run
dune build
ordune build tty
, I get nothing. No output, no error.
dune-project
file gets created with(dune lang 1.11)
in it.The
_build
directory gets created with onlylog
in it. The log has 4 lines:# dune build # OCAMLPARAM: unset $ /usr/bin/getconf _NPROCESSORS_ONLN > /var/folders/vy/ly11c9b91t32x62x39rrykyc0000gn/T/dune9d09bd.output 2> /dev/null $ /Users/emirkotan/.opam/4.08.0/bin/ocamlc.opt -config > /var/folders/vy/ly11c9b91t32x62x39rrykyc0000gn/T/dune3b0a02.output
Neither of these
.output
files exist (dune cleaning them up maybe?).That being said, if I do
dune build @@tty/all
then it compiles everything, and I get a working executable in_build
.I tried the “hello world” project we get with
dune init proj
, anddune build
works fine in that.So, I’m not sure if it’s my project layout or a missing config that’s not letting me use the “default” target?
PS: I tried these on both my Mac (Catalina) and Linux (Manjaro) machines, same issue.
