Subject: [dpdk-dev] [PATCH v2 6/6] mk: add "make examples" target in root makefile
Date: Fri, 9 May 2014 12:32:10 +0200 [thread overview]
Message-ID: <1399631530-24956-7-git-send-email-olivier.matz@6wind.com> (raw)
In-Reply-To: <1399631530-24956-1-git-send-email-olivier.matz@6wind.com>
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
