But the Wiki page says that it is faster than native compilation on RPI. To be honest, I prefer to compile using crossdev... Ok then, I will try re-setup crossdev on my PC and see if everything compiles well. If not, I will post the error message here. Thanks.

[gentoo-user] Questions on Raspberry Pi cross compiling
Hi guys, I am setting up cross compiling environment for my newly bought Raspberry Pi 3, under the guide of: https://wiki.gentoo.org/wiki/Raspberry_Pi https://wiki.gentoo.org/wiki/Raspberry_Pi/Quick_Install_Guide My original idea was to use crossdev to cross compile packages on my PC and install binaries on RPI. However I found it really nasty because it kept giving me the error message about "libintl: no such file or directory" during compilation of packages such as attr, python etc. And if some (even very few) packages fail to build on the PC, it is hardly possible to keep PC and RPI 'consistent'. (Yes, I did setup the 'make.profile' symlink to the right place.) So my question is: 1) If some packages are *doomed* to fail, how do you keep the emerge world environment consistency between PC and RPI? Or is my understanding of this method incorrect? 2) If it is not really a good idea to use crossdev, which one do you recommend between distcc and chroot method? (I googled but did not really get one answer about compilation speed.) Thanks in advance for any potential help. ;-) P.S. Does anyone have any idea about the 'libintl' error? I googled a lot but it seems that it should be part of glibc... Danny

Heck, if her phone works, that is likely all she plugs into USB except for a keyboard and rodent. I think this one still has PS/2 connectors for those tho. Pretty sure it does. Thanks for the ideas tho. I've heard of Mate but never seen it. Heck, I may end up switching if I find something I like. :-D Dale :-) :-)

I suspect someone put it there when I wasn't at home and knows where I keep them but it could be one I forgot about too. Anyway, I got four 1Gb sticks of ram in and am running memtest right now. So far, no errors. It has a small hard drive in it but not sure if it will be big enough for everyday use. May have to remove the one from the current rig she has. It should be big enough for me to test some distros out tho. ;-) Oh, single core running at 2.8GHz. It ain't blazing fast but it's likely faster than what she currently has plus the memory will help a lot. It's a older Dell. It has that flip up front that covers the CD/DVD drives. Some may recall all the torn up CD/DVD drives that caused. :/ Dale :-) :-)

I would actually expect more culture shock going from Windows to KDE than Windows to MATE. MATE and Gnome 2 are fairly close to Windows XP in design, granted some things are moved around. Gnome 3 is closer to Windows 8 and 8.1. Plasma 5 implements more of the things that one finds in Windows 10. (Notably those desktop environments came out *before* the respective Windows versions that share UI/UX design elements with them.) When you get to the low end of desktop environments or window mangers, they tend to clash with default window stylings and don't offer any window chrome. They were made by programmers with little or no background in graphic design. > The thing about her, she doesn't know a lot about puters but she doesn't > mind clicking around to find a way to get things to work.

First, I'm pretty clueless on what you are doing but notice something
that just may be related. Do you have zsh installed on your system? It
says zsh can't be found basically so perhaps it needs to be
installed??? I checked, I don't have it installed here but Nikos may
have it installed on his rig for some reason.

Again, I'm pretty clueless on this but thought maybe it might help. If
not related, ignore me. lol I have no clue what I'm talking about. ROFL

Emerging with USE="-gallium -llvm" works, but I was pleased with the solution provided by IceAmber, as it allows me to update mesa with the default flags (i.e. with those enabled). Since I don't use X11 much I feel happier using the default flags wherever possible (irrational of me, perhaps), unless they pull in too many dependencies. I appreciate all the help, Stroller.

Full Gnome or KDE are are probably as close as you're going to get to a Windows-like environment. Another option I'd toss out there is ChromiumOS, though it isn't really intended as a mainstream option on non-Chrome hardware. For $120 a Chromebook is pretty hard to beat, IMO (and a Chromebit or similar solution is even cheaper). That isn't what you're looking for, but when relatives ask me about PC recommendations I tend to lean Chromebook unless they REALLY need to run thick applications, because they're basically zero maintenance and idiot proof. Oh, and they're Gentoo derivatives. :) Nobody seems to be mentioning full Ubuntu - assuming it performs well it should of course be considered as an option as well. I'm all for Xubuntu but it might not be the best fit depending. -- Rich

The reason I went with KDE, I use it and it is closest to being windozeish. On occasion I read where some of those other "lighter" desktops are 'feature rich' like KDE is. Example, plug in a USB device and it pops up with a menu to select from a lot like KDE does. Is LXDE or Mate like that? The thing about her, she doesn't know a lot about puters but she doesn't mind clicking around to find a way to get things to work. Example, she plugged her phone in and figured out how to download pics and stuff. Heck, I don't know how to do that myself. Then again, my phone is so old, it may not can do that. It's a old Motorola Razr flip phone which I maxed out on contacts in my address book a while back. I want it to be easy for her but at the same time, she can figure things out. She also knows that as long as she is a user, she can't hurt much. She stays away from root except when doing updates. The biggest thing, her rig is old. It's older than my older rig and ancient compared to what I'm typing on now which is several years old itself but has upgrade room. lol Thinking about installing some of these on my rig and just seeing what it looks like. < thinking > Thanks.

We went and ate supper and let it go for a couple hours and it still wasn't done upgrading. Still, same problem after it was done upgrading. Someone else mentioned it being a bug for the older hardware and that could be it. Could be that old video card isn't well supported or at all. I'll keep Mint KDE in mind. I'm going to try to piece something together but most of the stuff I have laying around is old or doesn't work at all. Not good options really. Thanks for the info. Dale :-) :-)

Sticking to Ubuntu based distributions might be a good idea because there is a large userbase that has easy to search for answers to common problems. Plasma 5 might load her hardware too much.

Why does the task of flashing firmware walk hand in hand with mental illness so
near at the abyss of bricked hardware that often ?
Why can't it that easy as scripting plain TeX?

Re: [gentoo-user] Hardened again
Hello, I'm pretty certain that switching to the hardened profile won't cause any slot conflicts, it pretty much just enables some compiler flags ( PIE ( it's enabled in not-hardened profiles since 6.3.0 too iirc ) , stack hardening, fortify source, RELRO ) and hardening flags on a few packages ( e.g. glibc ). Please try it again, maybe the output of emerge --info and the output of your world emerge ( or just the error message , both as pastebin or something ). I'm not quite sure if I understand the second part correctly, but I guess you want to compile packages on your workstation for that smaller box? In that case it doesn't matter which kernel your host uses, just make sure to choose the correct -march value. You don't have to run the hardened kernel for the hardened profile to work ( although it greatly enhances it - but maybe not for long since GRSEC stopped publishing their patches ).

And as Mick mentioned, run your tool with linux32: $ linux32 ./tool It might just work without you having to do anything else. Since its statically linked, you shouldn't need any 32-bit libs. One thing that might prevent it from working, is that it might need an old kernel version or a compatibility kernel option that is disabled by default on modern kernel versions. But in the end, you won't know until you actually try it.

By default, Gentoo is multilib. Meaning it runs 32-bit software too. What libraries does the tool need to run? You probably can build those libraries with 32-bit support enabled. So what error message do you get when you try to run the tool? We can figure out which libraries it needs, and for those libraries you can then enable the "abi_x86_32" USE flag in package.use. On my system, I have that enabled for all libraries by default. My package.use has this in it: */* abi_x86_32 But you can just set it only for some packages if you don't want every package (that supports this flag) to be also built for 32-bit.
[gentoo-user] [OT] Small and dirty 32 bit environment just to flash my Bus Pirate
Hi, My Buspirate v36a needs a newer firmware. Unfortunately the flasher software is only available in 32bit and I run a 64bit modern Gentoo. The flasher is a commandline tool and needs no fancy movie player or fat surround sound. If there is no way (I fear) to setup a tiny quick'n' dirty 32bit environment on my Gentoo just to flash the firmware I woyld install a tiny quick'n'dirty 32bit Linux for my Virtual Box. Does one knows of a simple straight-forward distro, which knows of /dev/ttyUSB and is not a BEAST to download? Thanks a lot in advance for any help! Cheers Meino
[gentoo-user] Hardened again
Hello list, The recent discussion of hardening Gentoo prompted me to have a go at hardening this workstation. I followed the wiki[1] but when I got to emerge -e world I got scores of slot conflicts, maybe hundreds. So I backed off and restored the original system. Now I'm tackling a smaller box, following the same wiki, for which this machine is a compile host with a chroot containing the client's NFS-exported $PORTDIR. I have a question. The chroot and everything in it uses the host's kernel, which is not hardened. If I emerge -e world in the chroot, can I then use the resulting packages to install on the client? I suspect there will be subtle differences (or not so subtle) that prevent me from doing this. That would be a pity, because recompiling everything on the client, a quad- core Celeron N3150 at 1.8GHz, is likely to take a day or two.

This sounds like a video driver/compositor problem. My guess is some xorg/mesa driver was updated and the box is not able to process the latest code. However, to make sure no hardware problem is present, I suggest you take a look inside and blow away any cobwebs from video card cooling fan and heatsink. Removing and reseating the video card may also clean the contacts from any oxidization, which an old box may have. Finally, if there is an Xorg.0.log on this box take a look at it to confirm if this is a video driver problem. With systemd you would probably need to run: journalctl -e /usr/bin/Xorg (someone more knowledgeable with systemd could chime in here if I got this wrong) > What I'm looking for.

I don't know what Mageia has changed in their distro to cause these problems, but if cleaning/reseating video cards, RAM modules, etc. does not fix the problems you observed, then it's time to blame the software. Have a look at Mint with a KDE desktop: http://blog.linuxmint.com/?p=3292 Or Kubuntu: http://www.kubuntu.org/ However, I would expect both of the above to require 256MB video card memory and capability for hardware video acceleration. Really old video cards won't be able to provide this. Also 2G RAM is the absolute minimum for running Plasma or Gnome. If she can live without KDE, then I would recommend Lubuntu/Xubuntu: http://lubuntu.net/ https://xubuntu.org/ These can probably run with as little as 512MB RAM. > I've used Gentoo for so long, I don't know what other distros offer > nowadays.

There's a bigger world out there and there will be replacements for many of the desktop features she currently thinks are irreplaceable. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
[gentoo-user] On making customized profile again.
Hi. Trying to remove several packages from the "common" profile, i did copy mine to the same directory w/ that difference, that mine is located in /usr/local/portage instead of "common's" /usr/portage Then i copied /usr/portage/profiles/profiles.desc to /usr/local/portage/profiles/profiles.desc In the "local" file, i copied, in the corresponding section (x86), line x86 default/linux/x86/13.0/desktop stable pasted it right after it, and changed just its name: x86 default/linux/x86/13.0/customized stable But, when i run eselect profile list i don't see mine profile enlisted. So, where did i make mistake? Thank you for your time, Sthu.
