[odb-users] create_schema - compile error

[lemonnierk at ulrar.net]

Hi,

I started looking into odb a few days ago, and I decided to give it a try.
I used the binary packages on the download page to install it. I am trying to use SQlite.

When I try to use the function schema_catalog::create_schema(db) as seen in the examples, I get this

I am using a CMakeLists.txt found on github to compile both odb and Qt, worked fine until I added the schema.
I saw an old mail here with, I believe, the same errors, and the answer was that it was fixed in the next version.
Does the version on the website still have a bug for that ? Or am I just missing something.
I do include both ClassToPersist.hpp and ClassToPersist-odb.hxx in my main.cpp file, and the -odb files are generated and compiled.

Thanks
