To build the Schoof application, you must compile and link the modules 
together, with MIRACL C++ classes, and with the MIRACL library.

A precompiled Windows executable is available from
ftp://ftp.compapp.dcu.ie/pub/crypto/schoof.exe

So for Borland C++ (although MS C++ is a fair bit quicker)

bcc32 schoof.cpp poly.cpp polymod.cpp ecn.cpp big.cpp zzn.cpp crt.cpp
miracl.lib

For Microsoft C++

cl /O2 /GX schoof.cpp poly.cpp polymod.cpp ecn.cpp big.cpp zzn.cpp crt.cpp miracl.lib

On UNIX using g++, something like

g++ -I. -c poly.cpp
g++ -I. -c polymod.cpp


g++ -I. schoof.cpp poly.o polymod.o big.o zzn.o ecn.o crt.o 
miracl.a /usr/lib/libm.a -o schoof

should work

Note that the headers poly.h and polymod.h are assumed to be in 
the local directiory
