I note that that page says "The WinNTL distribution of NTL can be used
on any Windows 95 or NT platform (but not on Windows 3.11 or
earlier). Actually, there is nothing Windows-specific about
WinNTL. The source code is identical to the UNIX NTL distribution;
only the packaging is slightly different, and no assumptions are made
about the program development environment."

That "not on Windows 3.11" sounds discouraging but "identical to the
UNIX NTL distribution" sounds good. If this WINDOWS package fails, you
should try with the Unix distribution.


For us who isn't born with the knowledge what NTL is,
<http://www.shoup.net/ntl/doc/tour-intro.html> reveals that "NTL is a
high-performance, portable C++ library providing data structures and
algorithms for arbitrary length integers; for vectors, matrices, and
polynomials over the integers and over finite fields; and for
arbitrary precision floating point arithmetic."

After that you need to create the library. "info ar" for that
information.

That isn't very modularised. Use "-I" to gcc/gpp instead. "info gcc"
for more information.

Well as there aren't very many questions about NTL, it's no wonder if
it isn't in the FAQ. Furthermore that is ordinary compilator usage so
the compilator documentation is where you should look. To let gcc/gpp
know about libraries and include files you want to use "-L", "-l" and
"-I". Again, "info gcc" is your friend.


Right,
