The Getting Started guide says:
Cowboy setup
We will modify the Makefile to tell the build system it needs to fetch and compile Cowboy:
PROJECT = hello_erlang DEPS = cowboy dep_cowboy_commit = 2.10.0 DEP_PLUGINS = cowboy include erlang.mkThe DEP_PLUGINS line tells the build system to load the plugins Cowboy provides. These include predefined templates that we will use soon.
If you do make run now, Cowboy will be included in the release and started automatically. This is not enough however, as Cowboy doesn't do anything by default. We still need to tell Cowboy to listen for connections.
However, when I execute make run, this is the output I get:
erlang_programs/cowboy_stuff/hello_erlang% gmake run
gmake: *** No rule to make target 'run'. Stop.
If I use the following Makefile:
PROJECT = hello_erlang
PROJECT_DESCRIPTION = New project
PROJECT_VERSION = 0.1.0
DEPS = cowboy
dep_cowboy_commit = 2.10.0
DEP_PLUGINS = cowboy
BUILD_DEPS += relx
include erlang.mk
then everything seems to build fine:
erlang_programs/cowboy_stuff/hello_erlang% gmake run
DEPEND hello_erlang.d
ERLC hello_erlang_app.erl hello_erlang_sup.erl
APP hello_erlang

To assemble the working Makefile, I started with the Makefile generated by:
% gmake -f erlang.mk bootstrap bootstrap-rel
and I added the lines shown in the Getting Started guide that were not already in the Makefile:
PROJECT = hello_erlang DEPS = cowboy dep_cowboy_commit = 2.10.0 DEP_PLUGINS = cowboy include erlang.mk
So, maybe the Getting Started guide should say,
Add the following lines to your Makefile:
PROJECT = hello_erlang ... ... ... DEPS = cowboy dep_cowboy_commit = 2.10.0 DEP_PLUGINS = cowboy include erlang.mk
Yes relx needs to be added now. I will fix it for 2.11 releasing soon. Thank you!
I have updated the guide locally, it'll be part of 2.11. Closing, thanks!
