0/ Introduction
===============
Ccluster is a C library providing implementations of algorithms for computing
clusters of complex roots of univariate polynomials which coefficients are any
complex numbers, possibly given as oracle numbers.
It provides two binaries, bin/ccluster and bin/risolate, that take in input
a file .ccl (containing the definition of a polynomial)
and respectively compute clusters of complex roots and isolate real roots
of the input polynomial.
See bin/ccluster_spiral.c for example of use within a C program for
input polynomials given as oracles.
The implemented algorithm for complex root clustering is described here:
https://dl.acm.org/doi/10.1145/2930889.2930939
If you use Ccluster in your research, please cite:

The github repository is:
https://github.com/rimbach/Ccluster
There is an interface for Julia called Ccluster.jl:
https://github.com/rimbach/Ccluster.jl
and Ccluster can be used in Singular (see README.md for more informations).
1/ Installation and getting started
===================================
1 Satisfying dependencies
--------------------------
ccluster is based on FLINT and ARB.
In turn, FLINT and ARB depend on GMP and MPFR.
To satisfy the dependencies:
- download and install GMP, version 6.1.2 or later: https://gmplib.org/#DOWNLOAD
- download and install MPFR, version 4.0.0 or later: https://www.mpfr.org/mpfr-current/
- download and install FLINT, version 2.6.1 or later: http://flintlib.org/downloads.html
- download and install ARB, version 2.18.0 or later: http://arblib.org/setup.html#download
On linux OS, a proper installation place for those libraries is /usr/local
If your GMP and MPFR have been installed
2 Compile Ccluster
------------------
In ccluster repository:
./configure
make
optionally, you can install the binaries in /usr/local/ with
make install
if one of the 4 above mentioned library is not in a standard place, do
./ configure --with-XXX="path-to-XXX" where XXX is either gmp or flint or mpfr or arb
3 Run tests and get started about using the binaries ccluster and risolate
--------------------------------------------------------------------------
make test
