CRC32 link error under gcc 3.2.2

[Michael Hunley]

My app is cross-platform, made using several custom libs as well as 
crypto++.  Under Windows (XP home) it is compiled using MSVC6, SP5.  Under 
Redhat Linux 8.0 it is compiled using GCC (g++) 3.2.2 from the Boost.Jam 
build system (v1, not v2 if that means anything to you).  Under Win32 I 
compile crypto++ as a sub-project in my workspace using the DSP supplied 
from CVS (with the code-gen set to multi-threaded DLL).  I am using the 
current of Crypto++ cut from CVS as of this morning (with the Base64 fix, 
thanks).  On windows both the debug and release compile & link without any 
issues.  Under Linux, my debug builds fine (with a few warnings about 
unused vars), but my release build reports:
        "undefined reference to 'CryptPP::CRC32::CRC32[in-charge]()'; and
        "undefined reference to 'CryptoPP::CRC32::Update(unsigned char 
const *, unsigned)'
For all the functions I use it in (3 files with a total of 12 functions).

I think this is something in my build setup, but I cannot find anything, so 
I thought it couldn't hurt to ask.  Has anyone else run into a similar 
issue?  If so, any fixes?  Has anyone successfully built an app under GCC 
with the latest CryptoPP (5.1) using CRC32 in release mode (meaning the 
normal full opts, etc).  Anyone know of any command line compile link 
settings that might cause this?

thanks for any help.
