I own several packages that use cmake and I've taken to setting therelease type to RelWithDebugInfo like you suggest. One question I've had
but never gotten around to asking is: Regardless of whether you use
Release or RelWithDebugInfo, should we be building with -O3? It seems
odd that the rpm macro defaults to doing something that is explicitly
against the packaging guidelines.
Your sentence confuses me or I am missing somthing.
The FPG intention is to mandate using RPM_OPT_FLAGS. These so far have contained -O2. So, unless something has recently been changed, using -O3 would qualify as a bug somewhere.
I'd have to go back and look but the last flag wins, right? I've had cmake projects where RPM_OPT_FLAGS was used but the cmake options were appended, so I ended up with -O3...
