You will need the Coq proof assistant (>= 8.4)
with the Reals theory compiled in.
The .tar.gz file is distributed with a working set of configure files. They
are not in the git repository though. Consequently, if you are building from
git, you will need autoconf (>= 2.59).
Ideally, you should just have to type:
./configure && ./remake --jobs=2 && ./remake install
The environment variable COQC can be passed to the configure script in order
to set the Coq compiler command. The configure script defaults to coqc.
Similarly, COQDEP can be used to specify the location of coqdep. The
COQBIN environment variable can be used to set both variables at once.
The option --libdir=DIR can be set to the directory where the compiled
library files should be installed by ./remake install. By default, the
target directory is `$COQC -where`/user-contrib/Flocq.
The files are compiled at a logical location starting with Flocq.
