What tool do you use to build erlang program?

Question

Emake, makiefile or...? Thank you!

Answer 1

Here is the Makefile and Emakefile I usually use with make (origin unknown).

Makefile:

ERL=erl
APPFILE=myApp.app

all: ebin/$(APPFILE)
    $(ERL) -make 

ebin/$(APPFILE): src/$(APPFILE)
    cp $< $@

Emakefile:

{"src/*", [debug_info, {outdir, "ebin"}, {i, "include"}]}.

Answer 2

I use a Rakefile calling an Emakefile. Rakefile for flexibility and Emakefile for speed !

This build system is quite powerful, see erl_rake on GitHub

Generates .app files, builds releases automatically, runs EUnit test. And given it's build around a Rakefile, I've added easily pushing release to AWS and run my tests with etap instead.

I customized an old version on for my github projects.

Answer 3

We use a similar Emakefile as well.

{"src/*", [debug_info, {outdir, "ebin"}, {i, "include"}]}.

I use the erlang make functionality to run tests after succesful compilation.

Makefile extract:

all: compile

compile:
        erlc -o ebin +debug_info erl_make.erl       
        erl -pa ./ebin -eval "erl_make:make(development)" -s init stop -noshell

erl_make.erl

-module(erl_make).

-export([make/1]).

make(Mode) ->
    case make:all([{d, Mode}]) of
     error ->
      error;
     _ ->
      test_suite:test()
    end.

Answer 4

I propose my own tool :) Eake ... is very similar to rake from Ruby environment:

http://github.com/andrzejsliwa/eake

or

http://andrzejsliwa.com/2009/05/28/eake-narzedzie-budowania-dla-erlanga-bazujace-na-rake/

Here is example eakefile

-module(eakefile).
-compile([export_all]).
-import(eake, [task/3, namespace/3, run_target/2, run/1]).

execute() -> [

  namespace(db, "test", [
    task(migrate, "That is migration", fun(Params) ->
      io:format("in migration params: ~w", [Params]),
      run_target('db:rollback', [])
    end),

    task(rollback, "That is rollback", fun(_) ->
      io:format("in rollback"),
      run("ls")
    end)
  ])
].

and this is example using:

$ eake db:migrate
$ eake db:migrate db:rollback
$ eake db:migrate=[1,atom]
$ eake db:migrate=name

Use Sinan for building and Faxien for installing! Check out erlware.org. They are way better than a make file and provide ease of distribution. They are both in heavy active development and will be featured in: http://www.manning.com/logan/
