[gentoo-user] distcc to compile Gentoo on the laptop
Hello Gentoo users, I have one of the higher end pentium 3s running at 1ghz on a laptop. I have started to install Gentoo on it. Once Stage 3 (Hardened) and Portage were installed, the first things I installed were vim and distcc. My desktop is a amd quad core at 2.8 ghz stock. When I had Gentoo on it once before, compiling went really fast using MAKEOPT=-j5. My desktop is now running Fedora 16 and it's 64-bit, LUKS, RAID0. I looked up from the Gentoo Handbook and the Gentoo Wiki documentation about distcc. It all seems to assume that all the other computers are also running Gentoo. Also because the desktop is running 64-bit Fedora, and the laptop can only run 32 bit, there is the need for cross compiling. Here's all the issues I am running into that I'm asking for help to solve. 1. Both systems are not Gentoo. 2. Fedora has distcc and distccd available in the repos, but both packages are 64 bit. 3. The need for cross-compiling between architectures. The Gentoo Wiki says use crossdev. That package is available in the Gentoo repositories through emerge, but when I checked with my Fedora system, it was not. 4. According to what I read, gcc version a.b.c where a, b, and c are numbers, a and b need to be the same on both systems. It is ok for c to be different. My Gentoo has gcc 4.5.x while Fedora has gcc 4.6.x. So my question is if this is do-able and if anybody has experience doing this. I want to do the distcc both for the learning experience and because just emerging distcc on the laptop alone took at least 2 hours.

Start 'alsamixer', press 'F6' and see a list of your sound cards. I'm not sure about it, but maybe your webcam would be there, in which case you should just choose it and tune the volume for it.

[gentoo-user] iftop and 'ipv6' USE-flag
Hello! During a recent upgrade, I noticed that 'net-analyzer/iftop' now needs 'net-libs/libpcap' with the 'ipv6' USE flag. It seemed strange to me and I decided to ask here. Does 'iftop' really needs IPv6? Can't it be optional? Thank you. Vladimir - v...@ukr.net

Of course some processor power is used for the VM itself, but it should still significantly decrease compilation time on the laptop. Plus you can easily equip other machines with that VM and use their power too.

What I have tried so far: syncing the tree again. deleting the files in /usr/portage/www-plugins/adobe-flash/ deleting anything adobe in distfiles and in http-replicator. syncing the tree again. I still get the same error. Another thing I noticed. When I delete the adobe files in distfiles and try to emerge them, I get this on the tail end: 6750K 100% 189M=0.02s I have DSL here but to put it bluntly, it ain't nowhere near that fast. Heck, my hard drives ain't that fast. I run http-replicator but I also removed those files too so it is not coming from there. If it is not local, it can't download it that fast, where is it coming from? I only have one rig running locally, not that my network is that fast either. lol Is this just me or is anyone else having this issue? If it is just me, what else can I do to fix this? Haven't tried the latest, but it has happened here too in the past. I recall following pretty much what you've done to resolve this problem (except for the replicator thing). I seem to recall that on one occasion I had to try again the next day to get it to work, because I did not want to risk it with manifest-ing a dodgy download. I guess you could try downloading it manually directly from adobe? -- Regards, Mick signature.asc Description: This is a digitally signed message part.

Alternativly you can use the chroot to build binnary pkgs that can be installed on the laptop. There are 3 solutions I can think of: 1. Get a cross compiler for i686 working under fedora (have no idea about that, except manually setuping and compiling gcc) and setup the Fedora's distcc to use that correctly (this should go more or less according to the docs on the gentoo wiki regarding cmake and i686 vs amd64) 2. Create a gentoo chroot on the Fedora OS. Much lightweight that a virtual machine, you can setup the cross toolchain and distcc according to the wiki, you just have to play a bit with how to start the distcc inside the chroot (a plain /etc/init.d/distcc start inside the chroot won't work). Note that you can run a i686 chroot in an amd64 system, so you actually don't need to set up any fancy crosscompiler inside the chroot. Just run the chroot as 'linux32 chroot /mnt/chrooot ...' to make sure uname and similar get correct info... 3. Mount the laptops root filesystem through nfs on the fast computer (use no_root_squash on the laptop export to have correct root access to files) bind-mount something local (disk or tmpfs if you have enough mem) over /var/tmp/portage, chroot into it (don't forget to mount /proc, maybe /sys and maybe bind-mount /dev, though that should not be needed and don't forget 'linux32 chroot') and run emerges there... you will actually be running everything on the fast computer, only the access to the laptops disk will be through the network. With a fast network it should be a lot faster then working ont the slower notebook (note that if you bind-mount /var/tmp/portage inside the chroot, most of the compilation will be working with a local disk...) Compared to the distcc method, even the configure phases will be much faster... I do this often with my Pentium M 1.6Ghz thinkpad laptop and my quad core amd64 desktop... yoyo

You also need to pay attention and set CFLAGS correctly and not to native. Like: CFLAGS=-march=pentium3 -O2 -pipe -fomit-frame-pointer
