I have not done a whole lot of work with Qt, but they install all their binaries into /usr/lib/qt$ver/bin (at least for Qt4), and everything in /usr/bin is just a symlink to qtchooser, which then launches the correct tool and version and stuff. This looks like an upstream bug, since they should test for “moc -qt=5”, not just “moc” and/or use qtchooser to determine the available version(s) of Qt (or whatever Qt’s recommended way is). The easiest way to deal this this right now as far as I can tell would be to disable the Qt gui and go with the wxWidgets gui. You could also build it manually. Alec

My portage problem appears to be fixed. I hope. If anyone can splain what introspection does I'd be grateful. Alan did a fine job explaining what introspection is in general. In Gentoo, the introspection flag is only used by GObject based libraries; all the languages that natively supports introspection does it inconditionally, and (as far as I am aware) GObject is the only C object oriented library that provides introspection. Some years ago, you could get away without activating it, but nowadays is for all practical purposes mandatory. At least this is the case for GNOME 3; but I would not be surprised if it's also the case for basically any GObject based software; that covers all GTK+ 2 and 3 applications. The instrospection infrastructure is not only used (as Alan mentioned) to look inside a compiled class; it's also part of the automatic binding generation for other programming languages used by all GObject libraries (or at lest that's what I understand, please correct me if I'm wrong). Therefore, if you use Inkscape, for example, you'll need introspection since Inkscape is wrote in C++ using the gtk-- bindings. In general, I would recommend not to set USE=-* (an opinion shared by basically all Gentoo devs and most rational people), and let the default use flags to do their magic. But everyone is free to break their systems as they please. Regards. -- Canek Peláez Valdés Profesor de asignatura, Facultad de Ciencias Universidad Nacional Autónoma de México

[gentoo-user] booting from a usb flash drive
I believe I correctly dd'ed a minimal cd onto a usb flash (aka thumb) drive. I set the boot order on my new system (dell 7450) to have the usb storage device first. Sure enough I get the isolinux prompt and the kernel is loaded. However after asking for the keymap (I just hit enter) it types looking for the cdrom. There is no cdrom. It then tries to mount media /dev/sda[123] (which are dell and windows partitions). When this fails it announces no bootable medium found I tried adding the doscsi option, no change. What did I do wrong? thanks in advance, allan PS I did buy an external usb cdrom player and can dd the minimal cd to a blank media. However, I thought that I can install linux from a usb stick without a CD at all.

Why do you want to use the gentoo minimal CD? if your laptop has EFI I don't think you will be able to configure it properly. (I'm not aware if the minimal cd has an EFI boot partition, but by the way you describe your boot it seemes it doesn't, is this right? you can check the iso with fdisk -l ) Either way I still don't know why the manual keeps recomending using a minimal installation cd for amd64 platforms, especially desktop types. I recommend you to boot somthing that has X, a browser and Networkmanager, I see no point the unnecessary pain of installing gentoo with a console only CD on such newer hardware. It's just complicating your life because you want to.

Re: [gentoo-user] Re: grub-2 update
Solution that works for me:
- Compile the kernel with everything built-in leaving modules for the
few things that really need to be reloadable. Turn everything in
the bloody thing off. This avoids the need for a kernel-specific
filestem in the initrd.
- This since you don't need any modules in the initrd a
simple, static solution with busybox and init something
like:
#!/bin/busybox sh
/bin/busybox --install -s;
sync;
mount -t proc none /proc;
mount -t sysfs none /sys;
/sbin/mdadm --verbose --assemble --scan;
/sbin/vgscan--verbose;
/sbin/vgchange --verbose -a y /dev/vg00/root;
mount /dev/vg00/root /mnt/root;
mount;
exec /sbin/switch_root /mnt/root /sbin/init;
Add whatever you need for encryped filesytems, but it
won't have to change over time unless you change the
boot requirements.
Add a copy of busybox, switch_root, init, a static copy of lvm
into something like /boot/standard-init.cpio.gz. Mine is in
/usr/src/initrd with two sub's standard and rescue differing
only in the init script. A second initrd the last line commented
out as /boot/rescue-init.cpio.gz for cases where switch_root gets
unhappy.
#!/bin/bash --login
cd $(dirname $0);
for i in */init;
do
dir=$(dirname $i);
name=$(basename $dir);
(
cd $dir;
kleenfilz;
find . |
cpio -o -Hnewc |
gzip -9v /boot/$name.cpio.gz)
done
wait;
ls -lt /boot;
exit 0;
builds and installs the initrd's easily enough (kleenfilz
is a shell sub that removes editor cruft, no reason to leave
*~ files :-).
- Add /etc/grub.d/09_custom (i.e., into the config *before* the
junk that 10 adds in) like the one below. Note that this uses
the symlink /boot/vmlinuz with the static init. The current
portion comes from a second vmlinuz.stable symlink I curate
manually to the last kernel that lived for a while and never,
ever caused problems [not that I've ever botched a config
siwtch. no, really...].
The standard link and fixed init-script allow a static copy of the
grub config file with /boot/vmlinuz and /boot/standard.cpio.gz
hardwired.

- Run grub2-mkconfig once.
- Never touch the grub.cfg file ever again (unless you switch the

more.

The trouble I introduced a few weeks ago when I disabled introspection was subtle enough that I didn't realize until yesterday that I even had a problem. Portage had been doing mildly insane things that other people were not seeing, so as a test I removed the -introspection useflag and spent the entire day rebuilding packages. My portage problem appears to be fixed. I hope. If anyone can splain what introspection does I'd be grateful. It's a tricky concept if you haven't worked with Object Oriented Programming, so lt's look at the USE description: introspection - Add support for GObject based introspection Doesn't say much, right? Object Oriented languages tend to compile to byte-code, just like Java does, and so does Python. It's so the run-time interpreter can look up at run-time which function exactly needs to be run (this can't be determined statically). A really neat trick is to look inside objects not just to see what it has, but also how the innards work, what properties an object has, and other neat stuff. That's what introspect means - to look inside. This magic is what makes dynamic IDEs possible, where they prompt you for all manner of stuff while typing code, and even generate boiler-plate code that it hasn't been hard-coded to deal with. All sounds very fancy and theoretical. I know what introspection does, but I can't know if I need this type of it or not. Apparently (because stuff breaks horribly when it's off), packages that use GObject seem to rely on this feature. Therefore, switch it on and let portage get on with it. That's the best answer I can come up with. -- Alan McKinnon alan.mckin...@gmail.com

But what can happen at worst when you update a boot loader? That your boot loader fails to boot. So you can still boot from a LiveCD and select the option Boot from harddrive. Then you can easily fix the boot loader.

The packages that need it are those that use the gobject libraries from other languages than C, using the bindings generated with by the introspection part, the idea is a framework for easily building bindings to other languages from the C gobject libraries, e.g. all applications that use gtk3 and are written in python use introspection.

It's a tricky concept if you haven't worked with Object Oriented Programming, so lt's look at the USE description: introspection - Add support for GObject based introspection Doesn't say much, right? Object Oriented languages tend to compile to byte-code, just like Java does, and so does Python. It's so the run-time interpreter can look up at run-time which function exactly needs to be run (this can't be determined statically). Yes, but introspection (as a part of the language specification) is not limited to object oriented languages, nor compiled to byte code languages. C++'s 'virtual' keyword can (sometimes) force the compiler to generate introspection code if it absolutely cannot determine which function to call at compile time. C++'s templates could (maybe?) be considered static introspection. A really neat trick is to look inside objects not just to see what it has, but also how the innards work, what properties an object has, and other neat stuff. That's what introspect means - to look inside. This magic is what makes dynamic IDEs possible, where they prompt you for all manner of stuff while typing code, and even generate boiler-plate code that it hasn't been hard-coded to deal with. All sounds very fancy and theoretical. I know what introspection does, but I can't know if I need this type of it or not. Apparently (because stuff breaks horribly when it's off), packages that use GObject seem to rely on this feature. It is very nice and very fancy, but the implementation is not incredibly complicated in most languages (just pointers to tables of functions if memory serves). If anyone is interested in playing around with this stuff, Ruby has a pretty advanced object model, and classes can have different function implementations depending on what module you're in. Alec

Is not about fanciness, Is abut having the tools you need for the job, I understand you would choose a minimal if you were to try to boot an old celeron with less than 1gb of ram that would take forever to boot a modern livecd, but that is not your case, and the minimal and a 'fancy' have the tools my point is about being practical. BTW, I think if you had chosen the bulky live-dvd of gentoo it would have worked as expected.

The trouble I introduced a few weeks ago when I disabled introspection was subtle enough that I didn't realize until yesterday that I even had a problem. Portage had been doing mildly insane things that other people were not seeing, so as a test I removed the -introspection useflag and spent the entire day rebuilding packages. My portage problem appears to be fixed. I hope. If anyone can splain what introspection does I'd be grateful. Alan did a fine job explaining what introspection is in general. In Gentoo, the introspection flag is only used by GObject based libraries; all the languages that natively supports introspection does it inconditionally, and (as far as I am aware) GObject is the only C object oriented library that provides introspection. Some years ago, you could get away without activating it, but nowadays is for all practical purposes mandatory. At least this is the case for GNOME 3; but I would not be surprised if it's also the case for basically any GObject based software; that covers all GTK+ 2 and 3 applications. The instrospection infrastructure is not only used (as Alan mentioned) to look inside a compiled class; it's also part of the automatic binding generation for other programming languages used by all GObject libraries (or at lest that's what I understand, please correct me if I'm wrong). Therefore, if you use Inkscape, for example, you'll need introspection since Inkscape is wrote in C++ using the gtk-- bindings. In general, I would recommend not to set USE=-* (an opinion shared by basically all Gentoo devs and most rational people), and let the default use flags to do their magic. But everyone is free to break their systems as they please.

I'd like to know if anyone else is seeing spectacular speed performance with vbox-5.0.0. No noticeable performance improvement for me using hardware virtualization. The USB issue is because it no longer pulls the extension pack or additions packages as a dependency so you need to add them to your world file. Thanks, I will. A comment on nerd humor: while using vbox-5.0.0 my eye was drawn to a little black spot in the vbox main window, and I wondered if it was a dirt speck on my monitor screen. I put on my reading glasses to take a closer look. It turned out to be a new icon for the Clone selected virtual machine button in the form of a black-faced sheep. I conclude that this must be a sly reference to Dolly the Sheep, the first 'higher' animal to be cloned successfully, except that Dolly didn't have a black face, according to this: https://en.wikipedia.org/wiki/Dolly_(sheep)
