[odb-users] Building ODB 2.4.0 on OpenSuSE Leap 15.0

[Alexander Kuznetsov]

Hello.

I'm using OpenSuSE Leap 15.0 and GCC 7.3.1 or 8.2.1. Both compilers have been built from sources to include plugin support.
Tried to compile odb on that system.

Need help or any insight how to compile ODB on systems with GCC > 5.

As a note I have compiled everything on OpenSuSE 42.3 using GCC 5, however we're planning to phase out those systems.


Here is what I have during compilation (handpicked errors, the entire list is very big) :
