I created a project like this:
$> rebar3 new release foo
$> cd foo
$> rebar3 new app bar
The structure looks like this:
$> tree foo
|-- _build
| `-- default
|-- _checkouts
| |-- bar -> ../bar
| `-- rebar.lock
|-- apps
| `-- foo
| |-- include
| | `-- foo.hrl
| `-- src
| |-- foo.app.src
| |-- foo_app.erl
| `-- foo_sup.erl
|
|-- bar
| `-- src
| |-- bar.app.src
| |-- bar_app.erl
| |-- bar_sup.erl
| `-- barlib.erl
|-- config
| |-- sys.config
| `-- vm.args
|-- rebar.config
`-- rebar.lock
Now I want to include foo.hrl in barlib.erl:
-module(barlib).
%% API
-export([foo/0]).
-include_lib("foo/include/foo.hrl").
foo()->
ok.
compiling gives:
$> rebar3 compile
===> Verifying dependencies...
===> Compiling bar
===> Compiling _checkouts/bar/src/barlib.erl failed
_checkouts/bar/src/barlib.erl:5: can't find include lib "foo/include/foo.hrl"
When I remove the -include_lib directive and call rebar3 shell I can retrieve code:lib_dir(foo) and code:lib_dir(bar)
This looks good to me:
$> rebar3 shell
===> Verifying dependencies...
===> Compiling bar
===> Compiling foo

So, why does include_lib not work?
TIA
