[odb-users] error:Unknown pragma;

[袁袁斌]

Hi!
I've run all the examples successfully.After that,I start to build my own
project using odb.
Those files(.hxx,.c.xx,.ixx) are generated successfully,but after that,when
compiling the project on VS2008,
it says"error :Unknown pragma" in those lines that contain "#pragma db
....",
also it can't recognise the "db" from text " auto_ptr<database> db (new
odb::mysql::database (argc, argv));".
By the way, when adding the .ixx into the project, I ignored to create new
.rules file, since I don't know what that means.
So,my problem is, after the files are generated, how to build a new project
, how to compile , and at last create the .exe file.
Thanks!
Environment : vs2008, windows 7, sqlites.
