Ah, ok.

If you can get GCC 5 or later (just to build/run the ODB compiler,
everything else can continue using GCC 4.8.2), then I think it should
be pretty straightforward.

I would look into getting the RedHat developer toolset:

https://developers.redhat.com/products/developertoolset/updates

It seems you can get version 7 for RHEL 7 which has GCC 7.2.1.

Not sure exactly what you mean by this (if you want to use 2.5 ODB compiler
with 2.4 libodb* libraries, then no).

Generally, I don't believe there are any breaking changes in 2.5 compared
to 2.4 so it should be a matter of re-compiling your headers with the new
ODB compiler and linking to new libodb* libraries.
