My make.conf on my lappy. Really loving gentoo. recently (maybe a month ago) killed the win7 install and started using it full time. It's a challenge sometimes, being a hardcore windows user for so long (USED to play games before they all started to become crap), but overall it's a fun experience.

Any tips on how to tighten that up or nifty things to add would be awesome.

[gringo]

are this features not necessary from now?

confcache doesnt exist anymore and it should be preserved-libs IIRC, although im not sure the preserved-rebuild feature is available in 2.1.9.

thanks, it seems that preserved-libs have disappeared from portage, right now.

I found this page in the GCC documentation on Optimization Flags. It lists what -O3 imples, what -O2 implies etc, as well as a short definition of what each flag does.

Everything is just plain stable apart from kernels, openrc/baselayout, xorg/mesa/libdrm/radeon (from git, and mesa is linked with -z,lazy so it works properly with hardened gcc), and a bunch of apps (conky, gimp, mplayer, pidgin etc).

The next step is going no-multilib, but there's still a couple of things I use that rely on emul-linux-x86-* that I don't want to get rid of, as much as I hate installing big packs of pre-compiled, out of date binaries with multiple vulnerabilities in them, and I can't justify setting up a whole chroot just for wine and zsnes. If I was feeling brave/was bothered enough I'd just make my own emul-linux packages (tried it once before with little success, albeit following the deprecated guide) or try the multilib overlay

Note:-ffast-math breaks any javascript handling code that you compile.

It will cause konqueror, mozilla, firefox, (probably spidermonkey and openoffice) to crash.

It is just the particular js lib with the particular code. There really ought to be patches in portage prevent the flag since it is a a guaranteed code breaker.

You may be able to get away with -fassociative-math but I really don't know about that.

[darkstarbyte]

My Flags will drive you all crazy.

Wow. Are you guys editing your make.conf manually or do you have some sort of thing to manage it? The reason I'm asking, some people have some very cumbersome make files, but I'd like to explore my options without having to know every single flag, option etc.

Thanks
