I think I'm still misunderstanding the intention of the command.

install process? If so, which directory should I be running this from? (I
don't see a test.cxx in the cryptopp directory and searching online
suggests this is related to the google testing framework for C++).
If I run the following (without the test.cxx file as input, which probably
doesn't make sense but again I couldn't tell what function it's serving):
>> clang++ -g2 -O3 -I /usr/local/include /usr/local/lib/libcryptopp.a -o
test.exe
I get this error:
Undefined symbols for architecture x86_64:
"_main", referenced from:
implicit entry/start for main executable
ld: symbol(s) not found for architecture x86_64
Thank you for your help so far, I really appreciate it.
