****************************************************************************** There are two binary executables here (and compressed copies). One of them, ecdl.exe, was compiled with the GNU C compiler gcc 2.95.2: gcc -O2 -freg-struct-return -DPROD=4 -static ... The other, ecdl-ccc.exe, was compiled with Compaq's C compiler ccc 6.2.9: ccc -O5 -tune ev5 -DPROD=3 -static ... The speeds are very similar, 207 k or 209 k on a 500 MHz EV5 chip. Download using shift-click, "gunzip" the file if necessary, then "chmod u+x" it. Information on how to run it can be found in a "readMe.html" file with the source code in: http://cristal.inria.fr/~harley/ecdl7/source/64-bit/ ******************************************************************************
