[odb-users] C++17 and Exception Specifications

[Brian Coggins]

Hello,

I am using ODB 2.4.0 in a project which I would like to switch to C++17.  However, the ODB headers use exception specifications, and these are not allowed under C++17.  See the following error from clang:

>                                                 noexcept(false)

I was wondering if there is any plan to update the ODB headers to allow compilation in C++17?

Thanks,
