Note: At present I am much more actively supporting the MAGMA
version of HECKE.
However, HECKE is completely open source GPL'd software, so anyone interested
in downloading the sources and doing further work on it is very much welcome to
do so!

To get oriented and see what HECKE does look at the short tutorial: tutorial files.

Primes database: HECKE uses some of the LiDIA
arithmetic, so you should download the table LIDIA_PRIMES.gz
of LiDIA primes and gunzip it.

Remark: The file LIDIA_PRIMES, a list of primes, is sometimes
needed for the LiDIA functions during HECKE's operation. This is expected
to be installed with LiDIA in the ".../share" directory. If
the file cannot be found, you can execute hecke with the environment variable
LIDIA_PRIMES_NAME set to its path. For example, if this file is installed
in the "/usr/local" tree, this may work:
% LIDIA_PRIMES_NAME=/usr/local/share/LiDIA/LIDIA_PRIMES
hecke
(if you are using sh/bash). The 2003-09-29 executables for Mac OS X and
Redhat 9.0 will not properly find this file, so the above workaround is
necessary.

Executables and source code from 1999:

LINUX executable: Download hecke-july99.gz
(3MB), type "gunzip hecke-july99.gz", then "chmod +x hecke", and finally
"hecke" to run.

SPARC Ultra executable: Ami Fischman created a Sun (SPARC ultra) executable.
Download hecke.SUN.gz (2.3MB), type "gunzip
hecke.SUN.gz", then "chmod +x hecke.SUN", and finally "hecke.SUN" to run.
There are some caveats.

C++ source code: hecke-july99-src.tgz.
Extract this file by typing gunzip hecke-july99-src.tgz followed by "tar
-xvf hecke-july99-src.tgz". Look at the readme file.
