Re debug symbols
Should stay by default.
Another question is: What do you mean by "default" above?
When you "cmake .." w/o further adjustments, this should result in an O2
build.
Whether you'd like to support a build type type that switches from O2 to O0
+ gdwarf is orthogonal to my opinion in this regard.
I'm for setting default CMAKE_BUILD_TYPE to RelWithDebInfo and
not for modifying CXXFLAGS.
The problem here are the impacts beyond. Certain macros as Q_ASSERT are
noop if debug is disabled (and also some debug message printing) - I assume
this is why Jan would prefer to keep Debug as default. And the default
should be O2 ;-)
=> Either a new build type would be required or RelWithDebInfo be turned
into a more "Debug"-a-like mode (unfortunalely leaving Release as the only
"true" release mode)
I'd have to lookup whether it's possible w/ cmake to perform some smart
handling here (ie. either introduce another "FullDbg" build mode or detect
whether "Debug" was issued explicitly)
Cheers,
