# Generic package infrastructure
|
|
#
|
|
# This file implements an infrastructure that eases development of
|
|
# package .mk files. It should be used for all non-autotools based
|
|
# packages. Autotools-based packages should use the specialized
|
|
# autotools infrastructure in package/Makefile.autotools.in.
|
|
#
|
|
# See the Buildroot documentation for details on the usage of this
|
|
# infrastructure
|
|
#
|
|
# In terms of implementation, this generic infrastructure requires the
|
|
# .mk file to specify:
|
|
#
|
|
# 1. Metadata informations about the package: name, version,
|
|
# download URL, etc.
|
|
#
|
|
# 2. Description of the commands to be executed to configure, build
|
|
# and install the package
|
|
#
|
|
# The autotools infrastructure specializes this generic infrastructure
|
|
# by already implementing the configure, build and install steps.
