Those are not errors. Those messages are expected on Mac OS X. Did you get a
cryptest.exe at the end of the make? If so, run "./cryptest.exe v" and see
if the test completes. And then you can link your application with
libcryptopp.a.
Also, you can just type "make" and it will use the GNUmakefile
automatically.

Subject: Problems compiling crypto++ on OSX with GCC 4.2.1
I attempted to compile crypto++ using the standard GNUmakefile (make -
f GNUmakefile) on my Mac.
I need a 32bit build.
I've successfully compiled it on Windows 7x64 (MSVC2008SP1) and Debian
Lenny AMD64 (gcc-4.4)
(c++ -DNDEBUG -g -O2 -arch i386 -DCRYPTOPP_DISABLE_ASM -pipe -c)
The compilation succeeds, however I get the following errors
afterward:
libtool: file: algebra.o has no symbols
libtool: file: cryptlib_bds.o has no symbols
libtool: file: eccrypto.o has no symbols
libtool: file: eprecomp.o has no symbols

libtool: file: simple.o has no symbols
libtool: file: strciphr.o has no symbols
libtool: file: winpipes.o has no symbols

I'd appreciate any insight you guys might have, I assume there's some
flag I need to change to get this to build properly, but I've gone
through the makefile and haven't been able to find it through trial
and error. Let me know if there is any other information you need.
