FYI, I always build from RPMs but I disable the whole separate-debuginfo part
(which I and AFAICT most developers find obnoxious). There are many formulae
out there to do this, but in case anyone's curious here's what I have in my
.rpmmacros:
%__arch_install_post /usr/lib/rpm/check-rpaths /usr/lib/rpm/check-buildroot
%__strip /bin/true
%debug_package %{nil}
Back to the topic, "just install the debuginfo RPMs instead if you want to
debug" seems to be about -g whereas the real change here is to do with -O0 vs.
-O2 (vs. nothing). Regardless of whether debug symbols are built in or
available in a separate package, trying to debug code that was built with -O2
is kind of annoying. Having an easy way to configure with -O0, that works the
same way across .rpm and .deb and .tar builds, seems worthwhile.
