What version of Crypto++ are you using? Try version 5.2.1 with the GCC4
patch (get it from www.cryptopp.com) or the latest code from CVS.

Subject: compiling with gcc 4.1.1 on Fedora 6
Hi, all!
I've been using Crypto++ on windows (with MSVS 2005 and cygwin, gcc 3.4.4)
with success. However, my code has also to compile on Fedora 6. When I try
to (with gcc 4.1.1), I get the template-related errors shown below. I find
those messages rather puzzling because I cannot see why a function
receiving an argument of type T would not be called with an argument of
type T&, where T is a (basic) type with copy semantics. Any ideas or
advice? Thanks in advance.
Jorge.
