I fixed it by creating a symlink from /usr/lib/libstdc++.so.6 -> /usr/lib/gcc/3.4.4/i586-pc-linux-gnu/libstdc++.so.6

Ive done this also, but does this really need to be done? As I understand it CHOST is used only by gnu make. Though its nice to have it reflect your real i686 as oposed to i386, does it really mattrer one iota :?:

I recently changed the CHOST on my machine (I had set it incorrectly when I installed) I had no trouble emerging the toolchain (did this twice.) I had all of the "i386..." not found errors people had reported once I started emerge -e system. Emerging xorg-x11 and python first fixed those errors, I also did what was suggested here:

https://forums.gentoo.org/viewtopic-t-321340-start-0-postdays-0-postorder-asc-highlight-changing+chost.html

and it seems to be going fine. I am on my second emerge -e system and all seems to be going well.

Ok, finished all my emerge's everything went well. Only problem was the python and xorg-x11 one mentioned.

Hi,

I've installed an old harddisc with gentoo into a new computer with a pentium III processor. May I now change CHOST in /etc/make.conf from i486-.. to i686-.. without running into trouble?

The whole system seems to be compiled with CFLAGS="-03 -mcpu=i686 -pipe -fomit-frame-pointer".

And, ehm, I do have ssh connection to the box only...

Felix

Changing the CHOST will cause trouble the one way or the other. So you should really know what you're doing if changing it. If you only has ssh access to the box, you shouldn't do such experiments ;).

Regards,

Sino

Just thought i'd add my $0.02 worth:

I tried some of the suggestions as described in these posts, but they all failed miserably at some stage.
Then I came to thing about how gcc upgrades are handled, and came up with this:


Set your new CHOST in make.conf, and change optimization settings as needed.

in my case, I was changing from i686 to i586 (amd duron to pentium-mmx).

then:

emerge gcc
gcc-config -f i586-pc-linux-gnu-3.4.6
emerge --oneshot libtool
emerge -e world
env-update
source /etc/profile
emerge -e world

this seemed to work for me, even tho you're left with a stale copy of the old chost compiler.

Kind Regards,

John Hansen

I change i386 to i686 (CHOST) and I've the same problem...
and I fix it !!
Now not more:

    grep: /usr/lib/gcc-lib/i386-pc-linux-gnu/3.3.6/libstdc++.la: No such file or directory
    /bin/sed: can't read /usr/lib/gcc-lib/i386-pc-linux-gnu/3.3.6/libstdc++.la: No such file or directory
    libtool: link: `/usr/lib/gcc-lib/i386-pc-linux-gnu/3.3.6/libstdc++.la' is not a valid libtool archive


wait... I emerge kdelibs-3.5.3-r3 now... after - I give you needed command :)

p.s. I change CHOST from i386 on stage3 [for livecd] to i686.

Okay, kdelibs emerged successful !

just before
Code:

# emerge -av binutils-config gnuconfig m4 bison libintl gcc-config autoconf autoconf-wrapper automake pkgconfig make flex gdb patch
# env-update && source /etc/profile


:P

glibc is bugging me about changing CHOST:
Code:
 * glibc-2.4 is nptl-only!
 * NPTL requires a CHOST of i486 or better

!!! ERROR: sys-libs/glibc-2.4-r3 failed.
Call stack:
  ebuild.sh, line 1555:   Called dyn_setup
  ebuild.sh, line 668:   Called pkg_setup
  glibc-2.4-r3.ebuild, line 1079:   Called die

So I'm wondering, isn't it easier to just do a clean install rather than change the CHOST (and gcc-version) and do:
Code:
# emerge -e system
# emerge -e system
# emerge -e world
# emerge -e world

Especially nowadays, when Gentoo actually has an installer ?

I had the above problem. Being a bit lazy I have not reemerged world, but just the toolchain (twice), a few other tools and done a revdep-rebuild.

One thing I have noticed which does not seem quite right to me is that the revdep-rebuild does not catch all dependencies. The most recent one was that kdevelop depended on cervisia. As far as I can see, this is not explicit, but rather autoconf finds cersivia on the system and pulls it in. cervisia was only scheduled to be rebuilt later in the revdep-rebuild. Is this right, or is it a bug? I would have thought that a programme should not depend on libraries which happen to be on the system unless the USE flags explicitly state that it should.

I have changed the CHOST to i686-pc-linux-gnu and I am trying to update my system. Actually I use paludis instead of portage, and when I try to reinstall system says:

Any way to workaround this mess and get it working again? Well, my system is working perfectly but I cannot install/update packages due to Could not run/locate "i586-pc-linux-gnu-gcc".
