Hi,

I have problem when compiling GCC 4.5.3-r1.

Here is error output:

Im using hardened gentoo profile: hardened/linux/amd64

I have this problem on all boxes.

Thank you for help

Another note:
It seems that ebuild for gcc has been changed few days ago

So your config.log isn't the one that were produce by this build failure...

You have already build that gcc version maybe, and re-building it is now failing -> disable ccache and retry

Maybe that I take different config.log
/var/tmp/portage/sys-devel/gcc-4.5.3-r1/work/build/config.log -- is that one OK?

It is not rebuild but new installation:

Code:
emerge -pv gcc

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

gave the build.log then, portage should gave you the full path to it at end of a build failure
(and please try to build it without ccache, this helper tools is more a bugger than an helper)

FYI
I had the same problem. I was using an old version of gcc and kept on failing to emerge any newer version between 4.4.4-r2 and 4.5.3-r1.
Errors were : segmentation fault, internal compiler error or even header file not found (!?).
Other ebuilds were failing randomly.
Disabling ccache in make.conf fixed them all.
Thanks a lot krinn.

I don't think ccache is the culprit in this case.
I have a similar problem, and have never used ccache.

Being unable to upgrade gcc is a real pita, since doing a -uDNav world isn't possible :(

can you tell me where exactly build log is? error is above
without ccache problem occur as well

Thank you

I had the same problem after emerging libpng:1.5.
Repeatedly executing
Code:
revdep-rebuild --library libpng14.so.14 -- --keep-going

solved the problem for me.

Looking at the log, it seems like the compiler created in the first phase of the bootstrap process does not work. It would be interesting to see the corresponding config.log, but I have the suspicion that your CFLAGS might be the culprit. Try reducing them, removing the -fforce-addr (if you don't exactly know what this does, you should remove it anyway) and changing -march=native to something more conservative for this one compile.

Hi,
-fforce-addr is safe flag (also for hardened-sources) and -march=native is supported by GCC for long time.
In fact I can try it, but this is default setup in my distribution so I would rather find the root cause of this problem and solve it.

I was able to compile apps few days before (this is new installation).

Thank you for your help

Actually I have the same problem when upgrading gcc.

What I found out is, it is due to the CFLAGS, more congrete the "march=native"
Up till now I had: CFLAGS="-march=native -O2 -pipe"
After removing march=native it is working.

In the config.log I found:

Code:

configure:3233: /var/tmp/portage/sys-devel/gcc-4.5.3-r1/work/build/./gcc/xgcc -B/var/tmp/portage/sys-devel/gcc-4.5.3-r1/work/build/./gcc/ -B/usr/x86_64-pc-linux-gnu/bin/ -B/usr/x86_64-pc-linux-gnu/lib/ -isystem /usr/x86_64-pc-linux-gnu/include -isystem /usr/x86_64-pc-linux-gnu/sys-include    -c -g -march=native -O2 -pipe  conftest.c >&5
conftest.c:1:0: error: CPU you selected does not support x86-64 instruction set


Removing the march=native the command works fine.

I'm running as a qemu/kvm guest.

Not sure what has changed and why the new gcc won't compile with that flag any more.

Any ideas?

Same here. On my desktop with an Intel i7 930 gcc compiles fine with march=native, but on my laptop with an Intel T 4500 and the same march=native, the build breaks.

Is there a way to change the march= for this build only? And what should it be?

if it's that you can solve it with
Code:
mkdir -p /etc/portage/env/sys-devel
echo "-march=generic -O2 -pipe" > /etc/portage/env/sys-devel/gcc

I tried that, but it still tries to compile gcc with march=native. Just to verify that I did follow your instructions:

Code:
barbara ~ # cat /etc/portage/env/sys-devel/gcc
march=generic -O2 -pipe

I tried that, but it still tries to compile gcc with march=native. Just to verify that I did follow your instructions:

Code:
barbara ~ # cat /etc/portage/env/sys-devel/gcc
march=generic -O2 -pipe


I sniffed around a bit on the net, and rewrote the file as

Code:
barbara ~ # cat /etc/portage/env/sys-devel/gcc
CFLAGS="march=generic -O2 -pipe"
CXXFLAGS="${CFLAGS}"


And now gcc doesn't compile with "march=native". Yet it breaks, after more than an hour of compiling:

The /var partition on this computer is 20 GB of which 18 GB is free, so I don't think there's a space problem.

I've posted the entire build.log (9 MB) as http://solumslekt.org/temp/build.log.txt.

Hi,

its good to see progress on this issue. Anyway I'm running in KVM/Qemu as well, but I was able to simulate same problem in VirtualBox. I have third server on VirtualBox as well and I was able to compile GCC 4.5.3-r1 fine with march=native... I don't understand.

I will try delete GCC archive and fetch it again.

If there is anything else what I can test please let me know.

Thank you

Hi all,

I try to use leifbk hint:

Code:
cat /etc/portage/env/sys-devel/gcc
CFLAGS="march=generic -O2 -pipe"
CXXFLAGS="${CFLAGS}"


And I compile GCC successfully.

Should we notify somebody? GCC team? Ebuild maintainers?

Thank you

compiling with march=generic works for gcc itself.

After that I cannot even compile vim with the new gcc version

output is:

Code:
checking whether the C compiler works... no
configure: error: in `/var/tmp/portage/app-editors/vim-7.3.266/work/vim73/src':
configure: error: C compiler cannot create executables
