If Gentoo says it doesn't support graphite, then I'd stay away from it because Gentoo devs might not listen to your bug reports if you use it. I've been using gcc with graphite support for about a year or so and I've had zero problems so far. (I should also mention that I haven't measured how much difference it makes, either.) Very important to notice that *building* gcc with graphite support is not at all the same as *using* graphite support while compiling. To actually *use* your graphite support, you must include these CFLAGS while compiling each package: -floop-block -floop-strip-mine -floop-interchange That implies that you can turn off graphite support by removing those flags and recompiling your buggy package before filing a bug report. (I did that only once and discovered that it didn't change the bug at all.) IIRC, gcc doesn't use those flags while compiling itself, but I could be mistaken about that. I'll check again next time I compile gcc.

You know, bugs or > packages that don't work with it? I used it for @world and ran into a couple times when things were broken with it enabled... Don't really remember specifics. I didn't notice any perceivable speed difference, so I stopped using it just to simplify things in the future. :) In general,I have changed my CFLAGS to be less aggressive over the past years. I started with the most aggressive optimizations, and using -march=whatever... At some point I researched compile times for different optimizations and realized some packages were taking tens of minutes longer to compile! Surely whatever potential speed increase of -O3 vs -O2 was not going to give me tens of minutes cumulatively. If there is a package that really benefits from some specific optimization (and doesn't already set those flags itself in the ebuild), I'll set the CFLAGS for that individual package but leave the rest of world very simplistic. Same with -march, I've gone to using -mtune instead, after having to move hard drives into a system with different CPU feature set. And for virtual machines (in hosts I don't control, especially), they could be migrated to some other machine without my knowledge, and i don't want it to stop working if that happens.

[gentoo-user] DVD gives error but works fine
This is mostly for Joerg Schilling since he is the list guru for ALL things DVD but others with nice answers can reply too. ;-) Anyway. I have been making movie DVDs. Yea, I figured it out.

It does its preformat thing then pops up a error that it failed. Nothing more than that that I can see. It also spits the DVD out. I click load and it goes back in and finishes the burn normally and I might add that I have played several of these DVDs and they work fine.

OK, based on Stroller's responses to my DVD Movie backup thread (or whatever it was called) I'm trying out dvdbackup + mkisofs + growisofs. So far the best (as measured by my ease of getting through it) web site I found was an Arch Wiki page: https://wiki.archlinux.org/index.php/Dvdbackup From this I got 4 basic commands to try out: 1) Grab the data off the disc backing up everything dvdbackup -i /dev/dvd -o . -M 2) Create an iso image: mkisofs -dvd-video -udf -o ./dvd.iso ./MOVIE_NAME 3) Test that the iso works: mplayer dvd:// -dvd-device ./dvd.iso 4) Write the iso to a DVD disc: growisofs -Z /dev/dvd=dvd.iso So far I've had very mixed results, but it's early days: 1) The first movie I tried produced a black screen in mplayer with no audio and a number of messages telling me to file a bug report. 2) The second movie produced good results in mplayer but the iso file itself is bigger than 6GB implying to me that maybe it's dual layer or something else I haven't figured out yet.

Other than that, everything works fine. It gives the error but it appears there is no error. I just let it continue and it burns fine, plays fine on both my computer and a home DVD player. I just don't understand why I get a error. I also forgot to mention, it does this on any burn where I put in a new DVD. It doesn't have to be a movie, it can be plain data such as a backup or pictures etc. I just don't know why it is complaining when really nothing is wrong. I don't know if it is k3b or if it is something under the hood but I figure our guru would know. I can use that tkdvd program burner to test this if needed. I think it is still installed on here.
