SQLCipher + POCO C++

I'm trying to replace POCO's sqlite with sqlcipher on my Mac Lion. There's not a lot of info around in regards to the build process and replacement, however I figured I should give it a try.

I've got the sqlcipher amalgamation, then I've replaced sqlite3.c and sqlite3.h in the Data/Sqlite/src Poco directory with those of sqlcipher, added the SQLITE_HAS_CODEC and SQLITE_TEMP_STORE=2 params to the Makefile and tried to build this whole thing.

However I'm getting the following errors:

Undefined symbols for architecture x86_64:

Has anybody tried this before? Does anybody know a potential fix for this? Thanks!

Those are OpenSSL symbols, so you are probably not linking against libcrypto. Add -lcrypto to the linker flags.
