问题
I've been trying to set up a simple Erlang app using Rebar but can't get it to work. I followed the instructions on http://skeptomai.com/?p=56 to the letter, and when I run ./rebar -v generate
, I get this error:
==> Entering directory `/home/adam/erlang-test3/testing-rebar/apps/myapp'
WARN: 'generate' command does not apply to directory /home/adam/erlang-test3/testing-rebar/apps/myapp
==> Leaving directory `/home/adam/erlang-test3/testing-rebar/apps/myapp'
==> Entering directory `/home/adam/erlang-test3/testing-rebar/rel'
==> rel (generate)
{"init terminating in do_boot","Release mynode uses non existing application mynode"}
Crash dump was written to: erl_crash.dump
init terminating in do_boot (Release mynode uses non existing application mynode)
I get a similar error when following https://bitbucket.org/basho/rebar/wiki/ReleaseHandling. When following http://www.metabrew.com/article/erlang-rebar-tutorial-generating-releases-upgrades, I get:
{"init terminating in do_boot",{undef,[{dummy_proj,start,[]},{init,start_it,1},{init,start_em,1}]}}
How do I get rebar to work? My Erlang version is Erlang R14B04 (erts-5.8.5) [source] [64-bit] [smp:2:2] [rq:2] [async-threads:0] [kernel-poll:false]

I also started to learn erlang + rebar and I had the same problem some time ago and
I suppose you have problem in your reltool.config
file
- Add path to
lib_dirs
. I have{lib_dirs, ["../../", "../deps/"]}
- Add your app to app list. In my case this is -
{app, MY_APP_NAME, [{incl_cond, include}]}
Update: You have to rename you app. F.e. to erlangtest1. My working reltool.config
{sys, [
{lib_dirs, ["../../"]},
{erts, [{mod_cond, derived}, {app_file, strip}]},
{app_file, strip},
{rel, "exemplar", "1",
[
kernel,
stdlib,
sasl,
erlangtest1
]},
{rel, "start_clean", "",
[
kernel,
stdlib
]},
{boot_rel, "exemplar"},
{profile, embedded},
{incl_cond, exclude},
{excl_archive_filters, [".*"]}, %% Do not archive built libs
{excl_sys_filters, ["^bin/.*", "^erts.*/bin/(dialyzer|typer)",
"^erts.*/(doc|info|include|lib|man|src)"]},
{excl_app_filters, ["\.gitignore"]},
{app, sasl, [{incl_cond, include}]},
{app, stdlib, [{incl_cond, include}]},
{app, kernel, [{incl_cond, include}]},
{app, erlangtest1, [{incl_cond, include}]}
]}.
{target_dir, "exemplar"}.
{overlay, [
{mkdir, "log/sasl"},
{copy, "files/erl", "\{\{erts_vsn\}\}/bin/erl"},
{copy, "files/nodetool", "\{\{erts_vsn\}\}/bin/nodetool"},
{copy, "files/exemplar", "bin/exemplar"},
{copy, "files/exemplar.cmd", "bin/exemplar.cmd"},
{copy, "files/start_erl.cmd", "bin/start_erl.cmd"},
{copy, "files/install_upgrade.escript", "bin/install_upgrade.escript"},
{copy, "files/sys.config", "releases/\{\{rel_vsn\}\}/sys.config"},
{copy, "files/vm.args", "releases/\{\{rel_vsn\}\}/vm.args"}
]}.
