>>Further to my earlier message, the issue was fixed by amending the include for database.hxx from "database.hxx" to <odb/mysql.database.hxx> AND changing the line

>>auto_ptr<database> db (new odb::mysql::database ("odb_test", "odb_test", "odb_test"));

>>After these amendments, the files compiled and executed without any problems.  On running the make file included with the examples in the "hello" directory, libtool is used and perhaps this fixes the error.

 this is useful for anyone having the same problems I did.
