Re: [gentoo-user] why can't use print after installed CUPS ?
thanks for you reply, yes, i compile cups just by hand, and i compared with the files you send, though you cups version is 1.4.8, but i think the compare result is also value. most of files are the same as mine, but my libs are installed in /usr/lib64, not in /usr/lib. btw, my hadrware is ARMv7(omap3730). i think the test-page in web is good that means cups is working well, and i can get the right output while using lpstat -a, why application can't see print ? does there is something bettwen application and cups server ? if you emerge cups with no optional packge, you can use print well in application ? thanks again.

But it will probably work as long as you kernel included support for both types of hardware. If you're feeling adventurous, GCC 4.6, currently masked for testing, has specific -march options for the i7 and Sandybridge i7, according to the Gentoo Wiki CFLAGS page. Using 4.5.3 and -march=native, I had a couple of showstopping build failures, that were fixed by switching to -march=core2 -mtune=generic. Thanks a lot.

I agree with you (and not because my name is mentioned :-P).
I got lucky with USE graphite: gcc's homepage is quite clear; a 15-minute
reading convinced me to try graphite. But there are still lots of other USE
flags that sent me on hours of goose-chase before I can enable/disable with
conviction.
I'm not sure where to put the more detailed explanations, though; perhaps a
$PN.usedesc file in the package's directory? Kind of a complement to the
.ebuild file(s).

Pretty sure having the word 'optimizations' is sufficient for that.
The rest, you can look up. (Sorry, I hate Just google it answers
more than most, but I think it's appropriate in this case)
IMO, USE flags should have good meaning to people familiar with the
field the package is related to. Otherwise, to keep the same terse
length, you have to dumb it down...but how far do you go?
Now, in this case, I think the use of the word 'polyhedral' in the
description is just silly; that's not going to mean anything to anyone
not intimately familiar with compiler optimizations, if not intimately
familiar with graphite itself. It should probably read something more
like Add support for the experimental 'graphite' framework for loop
optimizations.
If I read his email correctly, Pandu indicated that multithreaded
environments are an example of the impact the new optimization engine
may have. I don't think he indicated that that was its specific
function, so I wouldn't go so far as to point out multithreaded
environments in the USE flag description.
and perhaps even a Kernel
help page style It is mostly stable. If unsure, say Yes.
I'm pretty sure that's the purpose of the default state of USE flags;
if it's enabled by default, it's if unsure, say Yes. If it's
disabled by default, it's if unsure, say No.
It would be ever so much more helpful for people who would like to
find out what new flags do before deciding whether or not to follow
the default recommended by the devs which are set into the profile.
Honestly, if you don't know (and I didn't), the best option seems to
me to be to ask a similar question to what Stéphane asked. Perhaps
what does the 'graphite' USE flag for gcc add?, but go on to say, I
see the USE flag description is '...', but what's the result?
(I'm not saying this type of hand holding is necessary for all flags:
enable support for non-Roman fonts via media-gfx/graphite2 is
perfectly understandable, as are most other flags about features a
user is likely to interact with. But for some of the more system
type flags (see also that python/perl flag business from the recent
months), I think the USE descriptions can stand some improvement.)
Sure. The problem is, what constitutes an improvement for each case?
(And perhaps it'd be a good idea to file bug reports against the
ebuilds.)
IIRC, the recent 'perl' USE flag kerfluffle was about removing 'perl'
support dropping tabs in an application, when those tabs were made
possible by a particular Perl script. I doubt that was the only
perl-based extension, but the argument made at the time was that the
USE flag that affected Perl support for the app should specifically
invoke that it affected that extensions.
That's like saying that a 'perl' or 'extensions' USE flag for irssi
should talk about disabling nick highlighting, when it would also
affect named windows, presence notifications...*anything* that depends
on its Perl extensions mechanism.

I don't know if libtool and binutils need to be remerged, but I did it just to be safe. 3. Now that gcc has been compiled with graphite support, you can turn on the CFLAGS flags necessary to fully utilize graphite. WARNING: some flags recommended by upstream *might* make some programs run worse; be careful. (I won't have access to my servers so I can't tell you which ones exactly). 4. At this point, I want gcc itself to be optimized. So, I remerged gcc and libtool and binutils (in that order). Might be unnecessary, but I'm anal like that :-) 5. Finally, universe-remerge (emerge --emptytree). As you can see, steps 4 5 are optional. And they indeed took a *humongous* time to complete. But I am quite satisfied with the result. Everything felt snappier compared to older boxen that haven't been graphite-ed :-) Of course, YMMV. Okay, found a forum thread discussing graphite and the proper CFLAGS: http://forums.gentoo.org/viewtopic-t-850087.html IIRC my CFLAGS looks very similar to the once @genstorm uses (scroll down to approximately 80% down the page). Now I never experienced *any* emerge failure, provided that I don't go higher than MAKEOPTS=-j3. Set it higher and several packages failed during compile. I don't know whose fault is that, but you've been warned ;-) Rgds,

Re: [gentoo-user] GCC with multiple targets
Which arch is it? Ppc, arm... ? If it is power pc I have a working gcc, but mine I got directly from Freescale - didn't emerged, but still got sources. Érico V. Porto 2011/11/18 Kamil Domański kdoman...@kdemail.net Hey guys, I've been trying to figure out a way to emerge GCC with multiple target architectures, so for example gcc-config -l would give me: [1] x86_64-pc-linux-gnu-4.6.2 [2] some-arch-linux-gnu-4.6.2 and with this I hope I could prepare a base system for an embedded device. Any information I find on the internet suggests using sys-devel/crossdev (which doesn't even support my target arch, according to it's wiki). Any suggestions? Regards, Kamil Domański
