Re: [gentoo-user] Regex question
Hi, I just wanted to comment something about Iain's suggestion: '^\?.*(http|https|ftp)://' If you add that '^' you're assuming that's the beginning of the string (as you may already know); the thing is I cannot see the cases where your URL starts with '?', the characters, and finally protocol and rest of URL. I mean, I can understand you found that string somewhere in the URL, but I don't see it being like that from the very beginning. Perhaps I missed something by the way, can you guys enlight me?

gtk-doc-1.8-r2 is the package that gets blocked, it isn't installed

yes it is! equery just told you so!
More interesting is that the first equery didn't list anything, but
the gtk-doc-am ebuild exists:

yes, the ebuild exists, but it's not installed! Therefore equery didn't
show it to you.

I think it just means gtk-doc-am wants a newer gtk-doc, so it's blocking
the one you have installed. You need to uninstall gtk-doc, and then you
can install a newer gtk-doc and gtk-doc-am.

Hello, It seems that my portage or python installation or the combination thereof has become borked. Whenever I run a portage-related program (emerge, eclean, portageq, etc) I get segfaults. Due to these being scripts, gdb is not of much help... I am able to start python normally and get it to add numbers so python is not completely hosed.

No, I'm not sure. The more I read the more I see different opinions! That's why I'm asking.

However, my 'gut' is more focused on the 'kiss' principal: (kiss whoever does the cooking and cleans the dishes) aka keep it simple. well, I like your line ;) -- gentoo-user@lists.gentoo.org mailing list I like it too!! -march is more specific than -mtune, that means that it takes profit of processor-specific instructions to increase performance, but breaking compatiblity with other processors as a side effect. Since you will be using the same code for different processors you don't want to be *that* specific, so you'll have to stick on the more general -march option. That's my theory, however, there's some dark point: gcc guides usually state that the main difference between -march and -mtune is _backwards_ compatibility, but doesn't say anything about _family_ compatibility. Quoting Gentoo GCC Optimization guide: On x86 and x86-64 CPUs, -march will generate code specifically for that CPU using all its available instruction sets and the correct ABI; it will have no backwards compatibility for older/different CPUs. If you don't need to execute code on anything other than the system you're running Gentoo on, continue to use -march. You should only consider using -mtune when you need to generate code for older CPUs such as i386 and i486. -mtune produces more generic code than -march; though it will tune code for a certain CPU, it doesn't take into account available instruction sets and ABI. Don't use -mcpu on x86 or x86-64 systems, as it is deprecated for those arches. So I guess it depends on how much time you have before your firewalls are production-ready. If you have plenty of time, I'd try -march out and see if no horrible crashes appear; if you don't want to play the crazy-lab-folk role, go for the safer -mtune. My two cents :-).

Hello,
I keep driving to make the size of the (gentoo) firewall as small(fast) as
posible to run on minimal resources. I have a mixture of old pentiums and
amd (k6) machines. I'd like to have one make.conf file for all the
systems.
Anybody see anything wrong (not optimized) with these settings?

CHOST=i586-pc-linux-gnu
CXXFLAGS=${CFLAGS}
MAKEOPTS=-j2
USE= -* hardened acl ssl crypt nptl nptlonly
Will -march=i586 work well with the amd k6 arch?
-fomit-frame-pointer (as no debugging wil)l occur on said machines)
Any comments on the USE flags? (a better way to minimize the installed
packages (which is vim and iptables and sshd)

gentoo-user@lists.gentoo.org mailing list
If you'd like to use the same make.conf for different machines you should
make sure they all have same processors or, at least, same family of
processors; in your case, I recommend using -mcpu instead of -march. Keep
in mind that K6 processors have their own -marc=k6 and might not be
comptable with -march=i586. More in /etc/make.conf.example.
About USE flags, I recommend using -va options on every merge, check
wich USE flags are enabled or disabled for each package and dinamicaly
make your USE variable up.
