Well, it can be a lot more than two screens of text. I have 1300 lines of package.use, almost all of it for abi_x86_32. I suspect that this the result of stuff like steam, wine, android-sdk-update-manager, and eternal-lands - all packages that involve graphics libraries and toolkits with huge dependency trees. Does that include the several lines of comments, often repeated, that portage includes in the auto-unmask output? I just checked two systems for abi_x86_32 and got around 130 lines in one and 220 in the other. The smaller number is for a laptop with a lighter install, although there isn't a massive difference between the total number of packages installed on each. Enabling the flag globally would probably affect the lighter, and slower, system more. 1. Portage's error messages when it is unable to produce a resolution are really confusing - somewhere in that wall of text are some clues that might eventually lead you to the likely 1-3 use flag or keyword tweaks that will fix the whole mess, but good luck finding it. Your example isn't even a terribly bad one - when you get those errors with something like qt it goes on forever. 2. Portage requires non-package-default use flags to always be specified explicitly either globally or per-package. I don't have to put qt in my world file to install kde, because portage knows it is needed and just installs it, and removes it when it is no longer needed. However, if something needs the qt use flag, portage can't treat it the same way. Now, there are certainly reasons why both of these issues exist. Solving them may not be trivial, and in the case of #2 perhaps there may be unintended consequences like unnecessary package rebuilds to progressively add/remove flags. And, of course, somebody has to do the work and since I'm not busy writing patches to portage right now I'm not going to complain too much about it. However, I really think that these are the real issue here. That, and automatically solving depgraph issues isn't trivial. No argument there. Portage's output can be unhelpful, obtuse, even misleading at times, but as I'm not in a position to do something about it, neither am I in a position to complain about it. -- Neil Bothwick [ Printed on recycled electrons ] pgpHpychKlvgz.pgp Description: OpenPGP digital signature

I just checked two systems for abi_x86_32 and got around 130 lines in one and 220 in the other. Yes, it does. The number of actual configuration lines is much smaller of course - probably 1/5th of the total. My point wasn't so much that this was an inordinate number of 32-bit packages, given my list of installed packages. It was more about the fact that on a system that I'm trying to keep fairly minimal other than my explicit preferences I end up with a huge config file that tends to mix my preferences with a lot of stuff that exists solely to satisfy the depgraph. It would be like sticking every package I install in my world set. There are some ways around this which I'll probably get around to on a rainy day: 1. Take better advantage of the fact that package.use can be a directory and have several files. The 32-bit flags would go in their own file. Autounmask goes in a separate file with a z at the start of the name and the intent is that lines in this file get moved to the appropriate files. Then from time to time the 32-bit flags can be deleted and re-created to keep them minimal as installed packages change. 2. What I'd really like to get to is a point where all my systems are defined by ansible configs or the like. I've already started container-izing many of my services to cut down on interactions - this way when I do random package updates I'm not dealing with mysql breaking or apache or whatever. However, this increases the amount of updating I have to do, and I'd like to bring that back down using a tool like ansible. -- Rich

Unless your screen is IMAX-sized, two screens of text is a lot more lightfooted than add extra libraries to nearly 200 packages - and most of that text is comments anyway. As Mick says, you get to choose, but the per-package approach is definitely lighter on the system. Enabling it globally may be less work though. I say may because when I tried that it introduced some breakages, so I went for the per-package approach. -- Neil Bothwick Things are more like they are today than they ever have been before. pgpnHCm9w4gm2.pgp Description: OpenPGP digital signature

Unless your screen is IMAX-sized, two screens of text is a lot more lightfooted than add extra libraries to nearly 200 packages - and most of that text is comments anyway. Well, it can be a lot more than two screens of text. I have 1300 lines of package.use, almost all of it for abi_x86_32. I suspect that this the result of stuff like steam, wine, android-sdk-update-manager, and eternal-lands - all packages that involve graphics libraries and toolkits with huge dependency trees. I still recommend the per-package approach, but I really think we're barking up the wrong tree here. I don't see the depgraph itself as the issue, or the ability to tweak flags per-package. I really see the bigger problem as the combination of two things: 1. Portage's error messages when it is unable to produce a resolution are really confusing - somewhere in that wall of text are some clues that might eventually lead you to the likely 1-3 use flag or keyword tweaks that will fix the whole mess, but good luck finding it. Your example isn't even a terribly bad one - when you get those errors with something like qt it goes on forever. 2. Portage requires non-package-default use flags to always be specified explicitly either globally or per-package. I don't have to put qt in my world file to install kde, because portage knows it is needed and just installs it, and removes it when it is no longer needed. However, if something needs the qt use flag, portage can't treat it the same way. Now, there are certainly reasons why both of these issues exist. Solving them may not be trivial, and in the case of #2 perhaps there may be unintended consequences like unnecessary package rebuilds to progressively add/remove flags. And, of course, somebody has to do the work and since I'm not busy writing patches to portage right now I'm not going to complain too much about it. However, I really think that these are the real issue here. That, and automatically solving depgraph issues isn't trivial. -- Rich

Lukily, this approach worked out. Currently I am updating and recompiling 199 packages but the blockers disappeared. If that will not work, I will remove the libav USE flag from /etc/portage/make.conf and try to update the world for the last time. Now, when everything ended well, I can accept that by the phrase to update the world for the last time above I meant that I was going to switch to other Linux distribution if this issue with ffmpeg-libav-multilib could not be solved in an elegant way, that is, without poking with every single package, which is really ugly. Luckily, everything ended well and I am happy to stay with Gentoo, but I should mention that, having such issues with multilib profile, enabling abi_x86_32 on per package base really should be unrecommended way to maintain the system and users should be warned about it. I'm afraid I cannot agree with you on this. On older PCs I would rather did not have to install abi_x86_32 for packages that I don't need to. The granular approach suits me better and also aligns better with the light-footed Gentoo approach. With this light-footed approach I had about two full-screen rubbish in my /etc/portage/make.conf file and kept adding on almost every update. Correction: in /etc/portage/package.use I think had you followed my suggestion you could have found that by remerging half a dozen packages at most, your conflict would have been resolved. I think so, but this is what I call ugly. Either way you got a result, so whatever works. :-) Yes, thank you.

[gentoo-user] Question for users of the Firefox browser
Hi all, I've been using Firefox for ages and something struck me recently as a bit odd. In the Windows version, if I click up into the address or search boxes, the existing contents are highlighted and if I begin typing, the existing text is deleted and what I'm typing becomes the contents. On the Linux version, under KDE, it doesn't. I have to click into the appropriate edit box, highlight the contents and start typing or hit either home/end and then start deleting before typing my new URL. If, for example, the existing text happens to be a google search string, this can be quite a bit of text to delete. So my question, I suppose, is multipart: 1) Is this by design? Is this the normal behaviour? 2) Have I set a USE flag wrong somewhere that causes this behaviour? 3) How do people get around the problem I mentioned above regarding long URL's, such as a Google search results? Any thoughts, greatly appreciated, Andrew
