In addition to the generic installation instructions given in the
INSTALL file, note the following.  You can see all options to
configure by typing ./configure --help.

1. DEPENDENCIES

(a) Both NTL and PARI are required.  If they have not been installed
in a place where the system will find them automatically (such as
/usr/local) then you will need to specify where they are when you
configure, like this:

./configure --with-pari=<path> --with-ntl=<path>

If you have Sage installed in SAGE_ROOT then you can use
$SAGE_ROOT/local for both of these.  Note that when you specify these
locations, no check is done that a usable version exists in that
place: it will be assumed that <path>/include and <path>/lib contain
appropriate include files and libraries, and the build will fail if
not.

(b) FLINT is optional (from eclib-2013-01-01) and only used for one
part of sparse matrix reduction, which is used in the modular symbol
code but not mwrank or other elliptic curve programs.  If a suitable
FLINT version is found (which must be at least version 2.3, to contain
the nmod_mat module) it will be used.  If in addition you have the
optional FLINT module hmod_mat (which does modular matrix operations
using 32-bit data types) this can be activated as follows; the
advantage being that the modular symbol code will require less RAM to
run: either (i) after ./configure, edit ./Makefile and all */Makefile,
setting FLINT_LEVEL=2 (instead of =1); or (ii) edit configure itself
similarly (in two places) and rerun it; or (iii) append
CXXFLAGS='-DFLINT_LEVEL=2' to the make invocation (and ignore warnings
about FLINT_LEVEL being redefined).

(c) Boost is optional (from eclib-2013-09-00) and provides parallel
capabilities in the form_finder class. Configure with --with-boost
specifying location of a fully built version of Boost, i.e. not
just the header files. After initial configure, if an error occurs,
run autoreconf and configure again. Autotools will initiate the
macros in m4/ directory and look for Boost.asio, Boost.thread, and
Boost.system. Refer ti ./configure --help for more configuration
options.

2. By default a lot of programs, including test programs, are built
and will be installed by "make install".  We only provide one option
here:  if you do

./configure --disable-allprogs

then the only program built will be mwrank.  (The whole eclib library
will always be built).

3. After running make, "make check" will build and run a lot of test
programs (in the subdirectory tests) and check that they give the
expected output (using test input files in tests/in and comparing with
the expected outputs in tests/out).

4. "make install" will install header files, library files, and test
program binaries in subdirectories include, lib, bin in /usr/local by
default, so that you would need to run "make install" with superuser
privileges).  You can specify an alternative place either by adding
--prefix=<path> to the ./configure command line.
