Re: [gentoo-user] Sync'ing and compiling pkgs for multiple PCs
Yes, your words about dependency and flexibility are valid, but this is also the most straightforward way to sync multiple machines at once. If you do need to emerge a package when the laptop is away from home then just --sync and it builds a portage tree at the missing mountpoint (if that makes sense). I'll consider that, but seriously, I've tried many ways, including rsyncd, to sync portage on my computers and I've settled for unison. Really, I like it for its simplicity of use and maintenance and the fact that my host only has the ssh port open. Sync'ing portage is not a problem, i'll explore different ways along the way. Dont try to convince me of other ways, this one is working (and I don't mind whatever downsides). Great! I'm glad you're happy with this. You're NFS exporting a sub-directory of /usr/portage, then, in order to share the built packages? As said, no. I'm using a separate copy on each host, which is sync'ed manually between those hosts. It may sound awful, but it actually syncs my /home directory, as well as my /root dir (where I keep important system stuff, like dev drivers source). The sync'ing is not very long and once done, each computer is completely independant and contains all my stuff i need. Which creates redundancy. I had tried NFS before, and failed, but I was not very interested and the first few obstacles made me drop it. It was before I tried gentoo and started my own personal 'renaissance' and learned so much. I'll try it again soon, but it's not my priority for now. I assume compilation errors. My usage is that I can turn distcc off for the duration of the compile when I see something like this, and not bother investigating it further, but I think the most likely cause is that a library is needed for compilation that is not present on the distcc server. Portage accepts the compile-time dependency because it is filled on the distcc client, the machine on which you've run emerge, but when that particular bit is sent off to the distcc server then that machine doesn't have the lib needed. Well, this is the whole problem. You were right about the compilation error. And if it *may* happen, then a full emerge -e will take days (considering system has 143 pkgs and world has 499 pkgs to build). Turning it off, emerge the package, turn it on, resume emerge once in a while is really against my idea of automatism! I might make a script that checks for binpkgs after emerge returns, and if no pkg was created, then disable distcc for that one, re-enable automatically... maybe prepare a report to send to the ebuild maintainer, to let him know of the issue and all relevant details. I would imagine that, assuming the above belief is correct, then the workaround would be to `emerge -o` the package on the other machines on your LAN (or the fastest machine, if you are using only that to emerge) before distcc'ing it. This is slightly inelegant. Clearly less and less transparent... i'd say cloudy. Seriously at this point, i'd just drop distcc completely. But I don't think I'll have to go that far. If you mostly have the same packages on all machines then hopefully you shouldn't encounter this scenario too often, although I'd also think that different USE flags could affect it.

Change flags in make.conf for generic compatible ones, compile a new kernel (I used genkernel for the migration, and compiled a specific kernel for the new machine later), emerge -e world and transfer the system (I used rsync, and had to deal with some network issues), everything worked (after some fine tunning for the new hardware) for me. Yeah, but that way you're doing emerge -e world twice. One on the old system, and one on the new system (to optimize for the specific CPU again; -march=native). It's usually faster to install from scratch and only transfer your setting to the new system. You are right too. IMHO, a new install is what you have to do for a such occasionally hardware upgrade. Note the emerge -e world is not what we need here as it will leave broken system packages (the system won't boot on the new processor). The '-e' option looks for the USE flags only. We are supposed to know what we do with Gentoo. Having hardware specific options makes the distribution in a possibly jail. Nevertheless, Gentoo and Linux offer all generic options to ensure x86 processor-like migrations. -- Nicolas Sebrecht

[gentoo-user] [maybe ot]Accelerometer hacks for Lenovo and -possibly- Macbook laptops
Sorry if spamming, but this is too juicy not to share.

Looks damn cool. Anyone with experiences to share? m.

Re: [gentoo-user] Sync'ing and compiling pkgs for multiple PCs
I would perhaps do some more investigation start a new thread about distcc problems. Yup, I'll do this major update on friday and report here about any issues strictly related to emerge and distcc. However, no news is good news! =) Thanks
[gentoo-user] [slightly OT] recommendations for streaming audio solutions
Hi all, This is a tiny bit OT but not totally. I used to have a streaming audio server setup using tunez (http://tunez.sourceforge.net/) but that is no longer in development (since 2004). Is there something in portage that I can use to stream audio over icecast, both mp3 and ogg and control it from a web frontend (maybe using mysql backend)? Grateful for any suggestions anyone has on this topic. thanks Matt No virus found in this outgoing message.

Re: [gentoo-user] Sync'ing and compiling pkgs for multiple PCs
You might want to take a look at Coda instead of NFS. It supports disconnected read/write: http://en.wikipedia.org/wiki/Coda_(file_system) I haven't used it though. Hey thanks! This seems quite cool! I've read about it on their website also and it would clearly fit all my requirements for a network FS. I believe it could even be used to replace completely my current use of unison. Definitely worth experimenting and if that succeeds, I'll consider migrating to it! Thanks again! Simon
Re: [gentoo-user] Thinkpad T61 HDAPS and sound card support
2008/8/1 Fernando Antunes [EMAIL PROTECTED]: I moved gentoo-sources to ~x86 and it is very stable for me. Thanks about that, I will have a try about the 2.6.26 kernel soon, also the hdaps patch for the 2.6.25 didn't work for me, I can update it to 2.6.26 BTW, with the new kernel, does the LED of Intel 4965AGN works? No LED for wireless card. My T61 has an Atheros chip set and it is not working for me, TX and RX packets are dropped. The 2.6.26 recognize the card using ath5k driver, but no LED. I tryed ndiswrappe, but no much progress until now. I think you may have a try with madwifi, last time I used madwifi for my fujitsu U1010 and it works fine. -- BR, Zhou Rui
Re: [gentoo-user] QT versions
On Wed, 30 Jul 2008 19:25:03 -0400 Daniel D Jones [EMAIL PROTECTED] wrote: Is it safe to remove QT3 from the system now? It seems like at one point that there were still packages in KDE that needed version 3 installed. I have both version 3 and 4 on the system. If I remove the qt3 use flag, enable the qt4 use flag and do an emerge --newuse, can I then unmerge version 3? On a sane system, if qt3 is no longer needed you could clean it with emerge --depclean --ask. That should in fact clean anything that's not in world and is not a dependency (might it be directly or indirectly) of a package in world. If emerge --depclean --ask doesn't report it on the output list, then there's something depending on qt3 installed. Remember that setting USE=-qt3 doesn't magically remove the dependency on qt3 for those programs that needs qt3. Kde 3.x relies in qt3, and no USE flag can change that. USE flags only change optional settings, for kde 3.x qt3 is not an option. However, most people don't usually care about sanity, and in that case, you should be careful when using --depclean. -- Jesús Guerrero [EMAIL PROTECTED] pgpPdzoRBR1mG.pgp Description: PGP signature
[gentoo-user] ERROR: cannot start hwclock as fsck would not start
Hi all, I've had the above error during boot for quite some time now so clearly it doesn't have too major consequences. :-) I would, however, like to understand what's going on and then, if possible, fix it. The first thing I tried was to grep for (parts of) this error in the /etc/init.d scripts but that yielded nothing. Using extra ewarns in /etc/init.d/hwclock and /etc/init.d/fsck I discovered that both hwclock and fsck *do* indeed run (but after the error is displayed). Looking in other places (/usr/lib/portage, /usr/portage, /etc) didn't yield anything useful either. lion ~ # rc-update show gpm | default ntp-client | default fsck | boot hald | default mtab | boot ntpd | default root | boot swap | boot keymaps | boot local | default nonetwork vixie-cron | default syslog-ng | default maradns | default localmount | boot consolefont | boot modules | boot hostname | boot net.lo | boot net.eth0 | default procfs | boot netmount | default sysctl | boot urandom | boot termencoding | boot hwclock | boot bootmisc | boot device-mapper | boot alsasound | boot Any ideas?

[gentoo-user] distcc trivial issue (i'm sure)
Hi, I've followed several docs about setting up distcc, one from the gentoo manuals and the other on distcc's website. I believe I understand the whole concept pretty well, but my problem is: only the first host compiles. I have 3 hosts, if I use nmap, it can detect the distcc port is open what version of distcc and gcc it's using. This proves it's running on all hosts. I have scp all distcc config files to all hosts, including make.conf (3 pcs are the same arch, etc). And of course option -j4 If I run emerge on a pkg, I will see the log populating on the 3 machines, there must be communication! After manipulating DISTCC_DIR, I got distccmon-gui to work. The monitor will show at the begining that localhost is compiling a small file during the ./configure. Then when compilation kicks in, localhost stops working completely and 192.168.96.64(ip of localhost on lan) starts working steadily. IP:*.64 is the first host in /etc/distcc/hosts. I have set the logs to debug level, which i believe is the level that will show ALL information (right?). I have read through that log during a compilation, specially at the start, and found absolutely no mention of the IP of any other hosts, nothing talking about connection issues or similar. I'm stuck here, I don't know what I'm looking for and help would be greatly appreciated! Thanks, Simon
