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
# ${RTE_SDK}/x86_64-default-linuxapp-gcc directory
user at droids:~/dpdk.org$ make install T=x86_64-default-linuxapp-gcc
# build examples for this new installation in
# ${RTE_SDK}/examples directory
user at droids:~/dpdk.org$ 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
# ${RTE_SDK}/x86_64-*-linuxapp-gcc directories
user at droids:~/dpdk.org$ make install T=x86_64-*-linuxapp-gcc
# build examples for these installations in /tmp/foobar
user at droids:~/dpdk.org$ make examples T=x86_64-*-linuxapp-gcc O=/tmp/foobar
