It's just a change in const-correctness in gcc since the doc was written. Use this insetad for DumpMessage.cpp: http://cryptopp.pastebin.com/8eFBpQMH
So, for example, if you create a directory called "scratch" in your home directory, here's a transcript of a successful session: $ cd scratch $ mkdir cpp561 $ cd cpp561 $ curl -O http://www.cryptopp.com/cryptopp561.zip $ unzip -a cryptopp561.zip $ make -j4 libcryptopp.a $ cd .. $ mkdir dumpmessage $ cd dumpmessage $ curl http://cryptopp.pastebin.com/download.php?i=8eFBpQMH >DumpMessage.cpp $ env CXXFLAGS="-I../cpp561" LDFLAGS="-L../cpp561 -lcryptopp" make DumpMessage $ ./DumpMessage 48 6f 77 20 64 6f 20 79 6f 75 20 64 6f 3f That's on OS X 10.6.4 with the latest developer tools installed.
