From 36d9324ed0a195cc7b84583ad8570fdc92ba1c80 Mon Sep 17 00:00:00 2001 From: Olivier Matz Date: Fri, 16 May 2014 10:19:01 +0200 Subject: [PATCH] mk: add "make examples" target in root makefile It is now possible to build all projects from the examples/ directory using one command from root directory. Some illustration of what is possible: - build examples in the DPDK tree for one target # install the x86_64-default-linuxapp-gcc in # ${RTE_SDK}/x86_64-default-linuxapp-gcc directory user@droids:~/dpdk.org$ make install T=x86_64-default-linuxapp-gcc # build examples for this new installation in # ${RTE_SDK}/examples directory user@droids:~/dpdk.org$ make examples T=x86_64-default-linuxapp-gcc - build examples outside DPDK tree for several targets # install all targets matching x86_64-*-linuxapp-gcc in # ${RTE_SDK}/x86_64-*-linuxapp-gcc directories user@droids:~/dpdk.org$ make install T=x86_64-*-linuxapp-gcc # build examples for these installations in /tmp/foobar user@droids:~/dpdk.org$ make examples T=x86_64-*-linuxapp-gcc O=/tmp/foobar Signed-off-by: Olivier Matz Acked-by: Thomas Monjalon --- doc/build-sdk-quick.txt | 14 ++++---- mk/rte.sdkexamples.mk | 77 +++++++++++++++++++++++++++++++++++++++++ mk/rte.sdkroot.mk | 4 +++ 3 files changed, 89 insertions(+), 6 deletions(-) create mode 100644 mk/rte.sdkexamples.mk diff --git a/doc/build-sdk-quick.txt b/doc/build-sdk-quick.txt index 8989a32a60..d768c446a7 100644 --- a/doc/build-sdk-quick.txt +++ b/doc/build-sdk-quick.txt @@ -1,12 +1,14 @@ Basic build make config T=x86_64-default-linuxapp-gcc && make Build commands - config get configuration from target template (T=) - all same as build (default rule) - build build in a configured directory - clean remove files but keep configuration - install build many targets (wildcard allowed) and install in DESTDIR - uninstall remove all installed targets + config get configuration from target template (T=) + all same as build (default rule) + build build in a configured directory + clean remove files but keep configuration + install build many targets (wildcard allowed) and install in DESTDIR + uninstall remove all installed targets + examples build examples for given targets (T=) + examples_clean clean examples for given targets (T=) Build variables EXTRA_CPPFLAGS preprocessor options EXTRA_CFLAGS compiler options diff --git a/mk/rte.sdkexamples.mk b/mk/rte.sdkexamples.mk new file mode 100644 index 0000000000..111ce91d99 --- /dev/null +++ b/mk/rte.sdkexamples.mk @@ -0,0 +1,77 @@ +# BSD LICENSE +# +# Copyright(c) 2014 6WIND S.A. +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions +# are met: +# +# * Redistributions of source code must retain the above copyright +# notice, this list of conditions and the following disclaimer. +# * Redistributions in binary form must reproduce the above copyright +# notice, this list of conditions and the following disclaimer in +# the documentation and/or other materials provided with the +# distribution. +# * Neither the name of 6WIND S.A. nor the names of its +# contributors may be used to endorse or promote products derived +# from this software without specific prior written permission. +# +# THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +# "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +# LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +# A PARTICULAR PURPOSE ARE DISCLAIMED.
