Let's see if things work out and if it gets any better ;-)

[gentoo-user] gcc 4.7.3 -- 4.8.3
Ok so I'm still on 4.7.3; but if I set 4.8.3 as the default, should I rebuild @system ? # gcc-config -l [1] x86_64-pc-linux-gnu-4.7.3 * [2] x86_64-pc-linux-gnu-4.8.3 I saw the news item about 4.8.3-SSP, which I think is a good idea, but how deeply, if at all, do I need to rebuild packages ? Is there any special steps I should take now in prepartion for 4.9.x? caveats? @system ? @world ? a specific list of packages only ? James

Based on my experience going from 4.7 to 4.8 was seamless, you can choose to not rebuild anything if you'd like. If you want to start taking advantage of -fstack-protector by default you can rebuild whatever you'd like, although if you're paranoid about security you should rebuild everything, ie. @system @world to make sure all your binaries and the libraries they dynamically load have the stack smashing guard built in. Going to 4.9 though is another thing.

James If I remember correctly (and I may not) the only thing I *had* to rebuild was webkit-gtk with 4.8 as I was getting errors with apps built with 4.8 and webkit-gtk built by 4.7. But I tend to set up a @world rebuild to run when I'm not on my machines if I have any issues anyway so I may not have run into other problems I might have had otherwise. Todd
