It is the same form as with every project built with Autoconf and
Automake.
# Basic setup.
cd ovs
./boot.sh
# First build dir.
#
# I name my builddirs beginning with "_". It is only a
# personal convention, although I think I got it from Paul Smith (see
# http://mad-scientist.net/make/).
mkdir _build
(cd _build && ../configure && make)
# Second build dir.
mkdir _clang
(cd _clang && ../configure CC=clang && make)
# And then after that you can just run "make" in both directories. I
# use a simple script.
I am not sure that it is worth describing in INSTALL, because I am not
sure that most developers want to do it.
