PostPosted: Sat Dec 12, 2009 9:25 pm    Post subject: GCC 4.5 testing Reply with quote

GCC 4.5 went into prerelease mode last weekish. I've created the tracker bug for 4.5 porting and have started build testing. As always, anyone filing good bug reports with patches included are welcome to help.

https://bugs.gentoo.org/show_bug.cgi?id=296658

At the moment I'm concerned about things failing with a standard configuration. Ie. if you want to test, please have your system built with safe CFLAGS, use the standard linker (not gold), and leave graphite and LTO off. Also, you need to be running ~arch. It might seem obvious but we always get people that try to run an unreleased compiler on a stable system.

Switching between compiler versions can break C++ programs that use symbol versioning. When switching to an older release from a newer one, if you encounter runtime errors like "libstdc++.so.6: version `GLIBCXX_3.4.9' not found", rebuild the package with the current compiler.

GCC snapshots and svn ebuilds are in the toolchain overlay. The gcc-porting overlay will be used again as a repository for patches not yet applied to the tree.

Bug reports must include patches, and all patches must go upstream.

To check, that warning's for using it as a system compiler, not for using it outside of portage for personal dev stuff, right?

(I thought I was fine, as I've been using 4.4.2 just fine in my mostly-stable install, but I got spooked.)

sure, that's fine. we just get always get a number of bug reports from people who use svn builds of toolchain packages on their stable systems and then complain when emerge @world fails. if it's not selected by gcc-config then you don't have to worry.

Thanks for confirming.

Running into this... I guess it's only an annoyance, but still...

Code:

/sbin/ldconfig: /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.0-pre9999/libstdc++.so.6.0.14-gdb.py is not an ELF file - it has the wrong magic bytes at the start.


What would be a good path to put this .py file? and would it require editing the toolchain eclass to fix this in the ebuild?

FYI. I hit this same problem too.

Would it be possible to get a lto useflag for the snapshots? Current gcc-4.5.0_alpha20100107 snapshot fails to compile.

LTO will be enabled if libelf is detected during the build. If you have elfutils installed it should work out of the box.

i know the ldconfig messages are annoying. just delete them if they bother you, they're just pretty-printers for gdb-7.0. i need to sit down and figure out where else they can be stashed that's outside of the library path.

if anyone's had trouble building boost the last week or two, it was fixed today.

gcc-4.5.0_pre9999 depends on elfutils with USE="lto" (which is wrong). And there is an --enable-lto, but I did not test if this is really needed.

why is it wrong?

lto is automatically enabled if libelf is found. i guess i could add a USE flag to make it explicit though.

it's an upstream issue. i think it's been fixed now, so wait until the next snapshot or try the svn ebuild.

My issue was that =dev-libs/elfutils-0.131-r2 isn't enough for lto. With 0.144, it works now . A use flag to have lto definitely enabled would be a good thing imo.

EDIT: Don't try to compile a kernel with gcc-4.5. Compile fine, but when udev it is trying to do it's magic you obtain a nice kernel panic.



I just found something tricky :( if you unistall libelf, gcc doesn't work any more.
I have to gcc-config 4.4.3; emerge elfutils gcc and then try again.
I suppose that at least a use flag shoul be used but I think that elfutils should be in system profile with a very VERY fat warnig.

On the other hand the following packages did not compile in a world rebuild (700+ packages) with graphite enable:

There are some of them that was related to gcc not being compiled with fortran, openmp and gcj. Some other hang in configure o link phase without any reason. I have to kill the prosses. I'm rebuilding gcc and then I will try again.

My issue was that =dev-libs/elfutils-0.131-r2 isn't enough for lto. With 0.144, it works now . A use flag to have lto definitely enabled would be a good thing imo.


Added.

GCC-4.5 finally hitting RC stage. I wonder if anyone gave up on testing GCC-4.5.0 ;P

that would probably do it. :wink:

i'd hold off LTO til libtool gets proper support. hopefully graphite works better than it does in 4.4.

rc1 isn't released yet. they're in code freeze right now, they'll branch sometime soon and then do RC's.

the 4.5 branch has been created and the live ebuild tracks it instead of trunk now. i'm not planning on adding ebuilds for the RCs - just use the live ones, they'll be close enough.
