Thanks. I have changed the use of sqlite3CreateFunc to sqlite3_create_function. I did not need to include the source code for sqlite3utf8CharLen because there's a sqlite3Utf8CharLen (note different capitalization) in the library. However, the definition of sqlite3ReadUtf8 and needed definitions READ_UTF8, xtra_utf8_bytes, xtra_utf8_bits, utf_mask are not in 3.4.2, so I needed to salvage from 3.3.13 source. This compiles and loads OK, but I'm wondering if there is a 3.4 way of doing what sqlite3ReadUtf8 did so that I don't have to carry the definitions. If anyone has a suggestion I'd appreciate hearing about it.
