# \brief Rules for building software that uses the GNU build tools
|
|
# \author Norman Feske

# \date 2011-02-02

|
#
|
|
# This file is meant to be included by 'target.mk' files. Instead of building
|
|
# a normal Genode target, the 'target.mk' file will then trigger the build
|
|
# of the contrib package specified with the 'NOUX_PKG' variable. The build
|
|
# consists to the following steps
|
|
#
|
|
# 1. Configuring the package by invoking the package's 'configure' script
|
|
# with the arguments required for cross compiling the package for
|
|
# Genode.
|
|
# 2. Building the package by invoking the 'Makefile' generated by the
|
|
# 'configure' script.
|
|
#
|
|
# Limitations
|
|
# -----------
|
|
#
|
|
# In contrast to the Genode build system, library dependencies are not covered.
|
|
# So if a library used by a noux package is changed, the noux package gets not
|
|
# relinked automatically. In this case, 'make clean' must be invoked manually
|
|
# within the build subdirectory of the noux package.
|
|
#
|
|
|
|
#
|
|
# Use name of the directory hosting the 'target.mk' file as 'TARGET'
|
|
# and 'NOUX_PKG' by default.
|
|
#
