# rebar package infrastructure for Erlang packages
|
|
#
|
|
# This file implements an infrastructure that eases development of
|
|
# package .mk files for rebar packages. It should be used for all
|
|
# packages that use rebar as their build system.
|
|
#
|
|
# In terms of implementation, this rebar infrastructure requires the
|
|
# .mk file to only specify metadata information about the package:
|
|
# name, version, download URL, etc.
|
|
#
|
|
# We still allow the package .mk file to override what the different
|
|
# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
|
|
# already defined, it is used as the list of commands to perform to
|
|
# build the package, instead of the default rebar behaviour. The
|
|
# package can also define some post operation hooks.
|
|
#
|
|

# Directories to store rebar dependencies in.
|
|
#
|
|
# These directories actually only contain symbolic links to Erlang
|
|
# applications in either $(HOST_DIR) or $(STAGING_DIR). One needs
|
|
# them to avoid rebar complaining about missing dependencies, as this
|
|
# infrastructure tells rebar to NOT download dependencies during
|
|
# the build stage.
|
|
#
