Hello;
I'm trying to implement some old code to update an old C++ MacOS
application, which uses an old version of Cryptopp (5.1.2) and, no matter
which version of cryptopp I use, I'm getting a "Duplicate Symbols" error on
linking.
What I'm doing:
1) Downloading a version of cryptopp from Cryptopp.com (as an example,
version 5.6.2) and uncompress the archive
2) There's "bug" in our source that requires a minimal change to
"filters.h" and "filters.cpp", adding a constant
3) In Terminal, navigate to that folder, enter $ export CXXFLAGS="-DNDEBUG
-g2 -O2 -stdlib=libc++"
4) Then enter $ CXX=clang++ make -j 4
5) After a bit, it builds just fine
6) Add the library to my Xcode project and make the headers available
7) Clean the project
8) Build the project, and at linking I get:
ld: 33 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
Expanding that out, it's finding duplicate symbols in "AESSupport.o" and in
"CryptoLib.o":

My "Minimal Case" project consists of nothing but the compiled cryptopp
library, main.cpp and the two cpp files that I'm attempting to integrate.
Any help would be appreciated, I've been banging my head on this problem
for a couple of days.
Thanks!
