when using both 4.1.2 and 4.2.2. No, I'm not using a hardened profile and none of my toolchain has been compiled using fstack-protector.

Yes, this seems to be a x86_64 profiled_bootstrap issue. Add this to the top of the ebuild.

Code:
GCC_MAKE_TARGET="bootstrap"

Thank you 'unK' for the how to.

I managed to install GCC 4.3 and sucesfully rebuilt world (emerge -e world). Now, im having errors when recompiling the kernel. I dont have the log at the very moment, but i was just wondering if any special steps or patch was required to rebuild the kernel in 4.3. I seem to find a few posts indicating im not alone having trouble building the kernel, but no concrete solution seems to exist.

anyone can provide a tip?

thanks guys, im learning a lot with all this :)

It is gcc 4.3 regression and I think it won't be solved soon due to the date of last post there.

Thanks unK,

Due to my lack of knowledge in the inner workings of GCC, i fail to understand how the problem with udivdi3 prevents from rebuilding the kernel. But in overall if i understand correctly, there is currently no way to rebuild the kernel in gcc 4.3; is that it?

If so, what do you guys do, rebuild your kernels with older versions of gcc?

thanks!


note: sorry if i ask noob questions, but gotta start somewhere ;)

edit: i just got home and i confirm the error message is: undefined reference to '__udivdi3'

This is a little patch to compile kernel with GCC 4.3.0. You need to apply it to the kernel source.

I am using it since yesterday, and it works nicely ;-)

Even after adding GCC_MAKE_TARGET="bootstrap" in the ebuild, I still get the following when emerging gcc-4.3-alpha snapshots. My last successful emerge was 20070810.

I also tried gcc-4.2.2 profile as well. Actually I use 4.2.2 instead of 4.1.2, which I think more stable.

Any idea? :roll: or...should I also enable "bootstrap" in USE flag? (testing right now...)

hello all,

tried tonight twice to compile gcc-4.3 20071012 and it fails at the same point ( end of stage 3 ) :

 *


and of course no error in the log.I added the line on top of gcc ebuild.
Maybe some of you have some hints, i will try to find my way but it looks dark :roll:
BTW, i've installed portage-bashrc-ng tonight by hand, is there an ebuild ? i 've read something like "if you have already emerged..." in the doc.

thx

Same error here with gcc-4.3.0_alpha20071012 and gcc-4.3.0_alpha20071019, under amd64 (Core Duo 2).

In the absence of knowledgeable people, may I make a lay suggestion to try -fortran if you don't need it?

Great, with the multilib patch it compil :-) (not able to compil svn-ffmpeg with it unfortunately)

I did it with the portage-bashrc-ng from "layman -f -o http://gechi-overlay.sf.net/layman.xml -a gechi"

See https://forums.gentoo.org/viewtopic-t-472386-start-0-postdays-0-postorder-asc-highlight-.html :-)

Even after adding GCC_MAKE_TARGET="bootstrap" in the ebuild, I still get the following when emerging gcc-4.3-alpha snapshots.

I also tried gcc-4.2.2 profile as well. Actually I use 4.2.2 instead of 4.1.2, which I think more stable.

Any idea? :roll: or...should I also enable "bootstrap" in USE flag? (testing right now...)

The multilib patch is still needed:

what is this patch please ? where did u get it ?

anyway it seems ok , i have finally my gcc-4.3
I have appplied the above patchs to compile my kernel.

But is there a way to disable CFLAGS filtering ?

I've set -march=core2 to test , but it is replaced at compile time :
Code:

 * Filtering out invalid CFLAG "-mach=core2"
 * Filtering out invalid CXXFLAG "-mach=core2"

Are you sure it is "march", not "mach"? ;p
