You will need the Coq proof assistant (>= 8.7)
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 library files are compiled at the logical location Flocq. The
COQUSERCONTRIB environment variable can be used to override the
physical location where the Flocq directory containing these files will
be installed by ./remake install. By default, the target directory is
`$COQC -where`/user-contrib.
