Anyone tried gcc 4.2.0?

[seren]

that patch was taken from Arch Linux for gcc 4.2.1 i would say its safe to remove in not 100% sure why i put it in anyways =/.

[kfiaciarka]

what is so special in gcc-4.2.0-piepatches-v9.0.7.tar.bz2 ? sth superior to portage patches?

[kernelOfTruth]

what is so special in gcc-4.2.0-piepatches-v9.0.7.tar.bz2 ? sth superior to portage patches?

it's hardened: pie, ssp

[kfiaciarka]

ok I've searched the web and I do know now. Sorry for ignorance before.

Having no luck with Gcc 4.2.1 hardened. The -Wno-overlength-strings error. Going from 2007.0 stage1 x86 to 4.2.1 with USE="-* nls vanilla multislot" emerge --oneshot gcc... Trying again atm. with "bootstrap" USE on

that won't work

you need to emerge a non-hardened gcc (e.g. 4.2.0 or 4.2.1) then build with it a hardened 4.2.1

ok, I didn't make it clear:
the ebuild of the non-hardened gcc (1st step) must not have support for hardened / pie

[Vlad.Sharp]

Sorry, I meant I did have the -hardened in USE as well. nvm. Building a vanilla 4.2.0 out of the official tree, then going to try your ebuild to build hardened

Edit: Grrr even the vanilla gcc from the tree won't emerge - same error. I think this is a stage1 problem - and I know how to fix it - gettext probably

Edit 2: STILL DOESN'T WORK - and it's nothing to do with the overlay ebuild - this is out of portage tree. Wait, do you need the toolchain eclasses from kevquinn's overlay?

The build of gcc was started like:

Code: Select all

USE="-gcj -gtk -hardened -multislot -openmp vanilla bootstrap" emerge -pv --oneshot =gcc-4.2.0

These are the packages that would be merged, in order:

Edit 3: Fixed somehow. Overwrote the sys-devel/gcc directory of /usr/portage (instead of having it in /usr/portage/local overlay) - and no more errors. Strange, as I don't have any custom eclasses defined. But it works (until the next sync, by which time I'll put the ebuild in /usr/portage/local overlay to keep it happy about version numbers and -uDn

kernelOfTruth - can you post the contents of your /etc/env.d/gcc/i686-pc-linux-gnu-4.2.1 file?

Also, (after emerging paxtest) - what does "paxtest kiddie" tell you? I can't get gcc and glibc to be hardened enough... (at least now I don't get text relocations made in every single program portage emerges...!)

if I look in more detail I think the only difference are the strcpy & memcpy functions [not those with "contains a NULL byte]

good luck

kernelOfTruth - you are definitely having more luck with hardened than I. What are your C(XX)FLAGS and LDFLAGS?

And what patches do you have for kamikaze5? (as an addon)

well I only replaced reiser4 with official latest reiser4-patch, grsecurity / pax unfortunately doesn't apply cleanly,
if I need additional security I use 2.6.21-klight6 with grsecurity + adaptive-readahead patch

it also works with -O2, -Os is somewhat better in terms of space & memory usage

[Vlad.Sharp]

kernelOfTruth: Thanks for the tip, I'll try -Os. Do you know why it keeps appending -fno-stack-protector when compiling paxtest??

Whatever -march=native is doing, it is not providing the equivalent code to -march=nocona.

-march=native should be equivalent to -march=nocona -mtune=generic on C2D. btw, use `size` when comparing binary files.

[Dinini]

Whatever -march=native is doing, it is not providing the equivalent code to -march=nocona.

Here's quick check to see what it is doing (I suspect it's "-march=nocona -mtune=generic" which I understand is the gcc 4.2 recommendation for core2). The output should show you the values native is using.

Code: Select all

touch test.c && gcc -v -c test.c -o test -march=native

where can I find working ebuild for gcc-4.2.1 ?

[kernelOfTruth]

where can I find working ebuild for gcc-4.2.1 ?

try my overlay:

click

it's based on seren's patchset + additional patches from kevquinn from pieworld

I built my whole world around it & it works

[Ishiki]

kernelOfTruth, I can't download patches for your ebuild...

[kernelOfTruth]

kernelOfTruth, I can't download patches for your ebuild...

you mean these ?

[Ishiki]

Thanks for the link.

It's just odd that those patches are not included in your overlay file and ebuilds have no information about the URL to them.

emerge -u gcc

You're welcome,

I don't know anymore where the post I posted the link to my overlay was / is but I think I referred to kevquinn / kevin quinn's overlay

EDIT: silly me, I just did emerge sync and emerge portage and now its working

[garythompson]

Hi people,
Is there a general consensus as to whether there is any advantage in moving my system to >=gcc-4.2.0 (I'm on 4.1.2)? I'm about to consider a recompile of my whole system and thought that while I'm at it, I will consider upgrading GCC.

Thanks.

[wrc1944]

IMO, if you're doing a complete rebuild and/or considering going to 4.2.0, you might as well go directly to 4.2.2, as it has a lot of the bugs worked out. However, I'm running only ~x86 systems for years, so if you're "stable" x86, you might need to do more researching. If "stable" emerge -upD gcc reports a 4.2.x version, you might be OK, but glibc and the toolchain might be a factor.

I'm just not sure about dealing with x86 systems, compiled with an ~x86 toolchain, as I've always been ~x86. This might be worth a look:
http://forums.gentoo.org/viewtopic-p-43 ... ml#4395755 My post at bottom of page one.

IMO, if you're going to adopt and compile a "stable" x86 system with an ~x86 "testing" version of gcc/glibc, you might as well go pure ~x86 in /etc/make.conf. Trying to mix the two causes more problems then pure ~x86.

Keep in mind the difference between "stable" and "testing" is relative to your level of Gentoo knowledge, and what apps you have installed on your base system. Some find more problems in stable than testing, as testing versions often have the needed fixes.

ah, well, sorry for the long delay

I simply must have overlooked your post

probably you'll get wrong results without that option that's why (not exactly sure ...)
