Comment (by rycee):

 Sorry about the vagueness. I used upstream `cryptopp560.zip` and
 `cryptopp561.zip` downloaded from http://www.cryptopp.com/. The 5.6.0 make
 file didn't have a target for a shared library so I copied that build
 target from 5.6.1, this is the only change I made to them. Building the
 `cryptest.exe` program and running it with `./cryptest.exe v` didn't show
 any problems. Similarly, there were no errors reported for `./cryptest.exe
 tv TestVectors/all.txt`.
