This is one of the features I really like about Gentoo. I specify
compiler flags in one place, /etc/make.conf, and everything that is
built uses those flags unless a package overrides it because it is
exceptional, which is rare. Hence, I build the entire Gentoo distro
with debugging enabled and it's as simple as adding something like this
to /etc/make.conf:
CFLAGS="-pipe -march=k8 -O2 -g"
CXXFLAGS="${CFLAGS}"
FEATURES="nostrip"
If *anything* crashes, I merely load gdb and debug it. Most open source
is fairly readable and most fixes are easily made. So I make the fix
and submit it to the caretakers of the project to which it belongs and I
never have to patch it again!
Regards,
Rob
