<br>
orionp and I were discussing on irc today, the idea to add<br>
-DCMAKE_BUILD_TYPE=ReleaseWithDebInfo<br>
to %cmake by default in /etc/rpm/macros.cmake , while making it easy to<br>
set/override manually, similar to how %_cmake_lib_suffix64 is currently<br>
handled.<br>
<br>
the idea being that many cmake projects default to Release (or not,<br>
sometimes goofy things like Debug)<br>
<br>
The idea being that many projects default to CMAKE_BUILD_TYPE=Release and<br>
end up pulling in -O3 (and -DNDEBUG).<br>
<br>
There's 2 issues we'd like some wider input. What disadvantages or side-<br>
effects are there to:<br>
<br>
1. setting a default CMAKE_BUILD_TYPE?<br>
<br>
2. building with -DNDEBUG by default?<br></blockquote><div><br></div><div>I own several packages that use cmake and I've taken to setting the release 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.</div>
