Man gcc. -pipe allows to use pipes (memory) instead of temporary files (disk). -O controls the resulting binary sometimes making it fast, large, and unreliable. I have seen ebuilds that enforce -O2 even when -O3 is specified. This can create a faulty impression that -O3 always works fine. -O and -pipe interact through the size of temporary files. Theoretically, -pipes may slow down compiles if there is not enough memory. Another factor that should be taken into account is the number of threads for make. For a PIII machine the generally recommended number is 2, but when the RAM is limited, say 384 megs, 1 thread with pipes works better. Ideally you should measure compile times for large projects like Open Office and find out what works best on your system. I would start with 1 thread -O2 and -pipe. -- Andrei Gerasimenko -- gentoo-user@gentoo.org mailing list

From the gcc manpage: -pipe Use pipes rather than temporary files for communication between the various stages of compilation. This fails to work on some systems where the assembler is unable to read from a pipe; but the GNU assembler has no trouble. The pipe is only for speeding up the compiling process. It does not speed up binaries. The -O3 contains some more optimizations than -O2, which can result in much bigger applications and may be contraproductive. The -O2 is widely recommended, but I guess you won't feel a big difference anyway. See man gcc for a more detailled description. - Sascha pgpBuPCWnDVK5.pgp Description: PGP signature

Dan, I used Sylpheed-Claws for several years, with the past 6 months being on Gentoo. Given the still rapid pace of claws' development (as Neil mentions), the only way to have new features and fixes for old is to turn on ~x86. Even though officially "experimental", the releases are all very, very usable. My recommendation is to add mail-client/claws-mail to package.keywords and run the latest version of claws-mail. You'll end up with a good program that, if not perfect, is 99.9% perfect :-> Regards, David -- gentoo-user@gentoo.org mailing list

I don't know exactly about kdm behaviour, but gdm reads .desktop files from /etc/X11/dm/Sessions/ directory.

I've found time to move things off the RAID to I can compare with freshly formatted filesystems.

[gentoo-user] Install Stage feature request and bug report.
Just a small request of the gentoo stage developers... Would it be at all possible to include rsync in the next round of development? Also, has ANYONE on this list been able to serve nfs shares from any of the 2006.1 stage3 iso's? I've recently cloned a 2006.1 install to a small cluster of Dell Optiplex GX50's and it would have been a god-send if I could have accessed the targets via rsync or nfs. On the 2006.1 stage3 iso, there's an nfs.ko kernel module and enough utilities to run a server, but it fails to work... It errors out with "nfssvc function not implemented" and rpc.nfsd fails to start Possibly the provided nfs.ko does not match the included kernel? However, the stage3 sshd daemon and nfs client works perfectly and a simple cp -a followed by a grub setup and each of the nodes in the cluster installed and runs perfectly. I now have Gentoo 2006.1 running as a 5 node distcc compile cluster... Awesome... -- Jerry McBride -- gentoo-user@gentoo.org mailing list

I know gdm, which I use, lists session managment options like Fluxbox and KDE based on the presence of startup scripts in some folder somewhere in /etc/X11. The ebuild should put them there, but I'm not sure, especially for kdm, what that entails or whether it'll actually be done in your case. You might be able to set up a custom script in ~/.xession to start up windowmaker, if you can figure out how to do so from the command line, and then select the "custom" option if the windowmaker ebuild doesn't support adding itself to the kdm menu.

If your system is not up to date across the piece, some software will no doubt will complain with whatever is left behind.
