I haven't followed the thread too closely, where is the best ebuild for the gcc snapshots right now (toolchain overlay?) and do I need to manually add patches, or are they in the overlay?

ebuild refers to gcc's files in main portage tree, so there is no additional files needed.

If you wait a day or so there will be a new snapshot available.

enderandrew · Post by **enderandrew** » Fri Sep 21, 2007 6:55 pm

Will do. I don't have much time today regardless. So I'll probably start the install tonight, and then build the toolchain tomorrow.

unK · Post by **unK** » Fri Sep 21, 2007 7:39 pm

kdelibs are fine. but there are some packages which still don't compile and tar is one of them, so I don't know if you'll be able to bootstrap from stage1.

nbvcxz · Post by **nbvcxz** » Fri Sep 21, 2007 7:47 pm

you can build almost whole system with 4.3.0 - some packeages will fail; I made a small table with the most common failed packages - but if they refuse compiling with 4.3.0 there are no problems to build them with 4.2.0; details

hope it is useful

btw. has anybody succesed with compiling any recent kernel with 4.3.0?
mine always fails with System.map creating (tried with mm, kamikaze, ragnarok etc.)

me not.

Btw, I recompiled world using latest snapshot and my system is still working

so I made a table similar to nbvcxz's where I put packages, which failed for me. I also wrote several small patches which allow some of them to build -> http://www.unknownart.webd.pl/o/gcc43/

cheers.

Just a little question, at the start of this topic it was specified that gcc isn't supporting
sse3 and sse4 and the -msse3 ,-msse4 flags are worth nothing.

However, the gcc-4.3 changelog is saying a different thing:

Support for SSSE3 built-in functions and code generation are available via -mssse3.
Support for SSE4.1 built-in functions and code generation are available via -msse4.1.
Support for SSE4.2 built-in functions and code generation are available via -msse4.2.
Both SSE4.1 and SSE4.2 support can be enabled via -msse4.

(from http://www.gnu.org/software/gcc/gcc-4.3/changes.html, note that's not just support
but also code generation claim....)

Can anybody say who's wrong (and why...)?

have a look at

100% Core2Duo Gentoo happing here. AKA GCC-4.3.0

I think DualCpuUser's modifications should do the trick for you

catchword: flag-o-matic.eclass

Yup, I've compiled kamikaze9 with gcc-4.3 happily. It's my current running kernel.

Why do you use "-march=native" ?

Nevermind, read about native, seems fine.

yay as [profile=159137]unK[/profile] announced at Polish forum - I can confirm that you can compile the whole toolchain (with glibc but must use glibc-omitfp) and almost whole system (except of cpio tar and openssl) from portage with gcc-4.3.0_alpha20070921

thanks for the heads up, i've been meaning to do a bootstrap with gcc-4.3 and -march=core2

I have all the above compiling, I use autopatching from bash-rc (look at previous posts).

A little update here, I added a few patches more.

b33fc0d3, have you got any patches for packages which still fails?

openssl didn't even need a patch here ... and when my world compile completes i'll add the patches for the things i can fix, usually simple header includes.

nbvcxz · Post by **nbvcxz** » Fri Sep 28, 2007 5:06 pm

regarding the patches - is this any chance to have them in official portage tree soon?

@laughinggnome
I use no additional patches to compile toolchain and system with gcc-4.3.0_alpha20070921
the only packages that failed with system recompiling are: cpio, tar, openssl - they are built with gcc-4.2.0
I have no idea if any of the three affect on compilig busybox or grep - but I don't think so.
It can be specific for march=core2, but it need to be confirmed. The second reason could be taht you haven't recompiled toolchain / system properly
than try to use http://68.111.182.197:9002/emwrap.sh
