 Posted: Sat Sep 20, 2008 1:58 am Post subject: broke my system after changing CHOST [SOLVED] |
 |
|
I changed my CHOST flag, without folloeing the HowTo (yes, I'm guilty!)
I tried to change it from i486-pc-linux-gnu to i686-pc-linux-gnu
now I want to come back to i486, but there's no way i can compile gcc...
here's my make.conf
| Code: |
..
CFLAGS="-O2 -march=prescott -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"
CHOST="i486-pc-linux-gnu"
MAKEOPTS="-j3"
..
|
and here's the output of emerge gcc
/var/tmp/portage/sys-devel/gcc-4.1.2/temp/build.log
| Code: |
..
--enable-__cxa_atexit
--enable-clocale=gnu

mmm that /etc/env.d/binutils/i686-pc-linux-gnu-2.18 doesn't look too good...
and this is
/var/tmp/portage/sys-devel/gcc-4.1.2/work/build/config.log

running configure, to aid debugging if configure makes a mistake.

so I guess the error is "gcc: error trying to exec 'as': execvp: No such file or directory"
any idea???

Hi,
Does 'binutils-config -l' list i486* as an option? If not then I would try and recompile binutils with the i486 CHOST and try again.
Edit: I just noticed your other post. You just want to recompile binutils with the CHOST you want to use, then make sure it's selected with binutils-config.

thanks a lot for your reply
well, i guess now i knoe where the problem is:
| Code: |
gentoo ~ # binutils-config -l
[1] i686-pc-linux-gnu-2.18 *
gentoo ~ # gcc-config -l
[1] i486-pc-linux-gnu-4.1.2 *

I had already tried what you said, but no luck...
this is the build.log
| Code: |

i think I have an i486 gcc and a i686 binutils... so i can't compile anything
maybe I coul get a whole toolchain in a binary package???
...
anyway, I kept going around and found that "as" is a command
so
| Code: |
gentoo / # find / -name as
/usr/share/locale/as
/usr/libexec/gcc/i686-pc-linux-gnu/as
/usr/i486-pc-linux-gnu/bin/as
/usr/i486-pc-linux-gnu/i686-pc-linux-gnu/binutils-bin/2.18/as
/usr/bin/as
/usr/kde/3.5/share/locale/l10n/as
|
and saw that in usr/bin i have a bunch of broken symlinks
i had to
ln -s /usr/bin/as /usr/i486-pc-linux-gnu/i686-pc-linux-gnu/binutils-bin/2.18/as
and then I had to do the same with ld, ar, well... and who knows what else
right now it is compiling...
i hope that when this thing finishes, if it does, it will fix all the symlinks... |

wel it compiled!!!
now I have
| Code: |
gentoo / # find / -name as
/usr/share/locale/as
/usr/i486-pc-linux-gnu/binutils-bin/2.18/as
/usr/i486-pc-linux-gnu/bin/as
/usr/bin/as
/usr/kde/3.5/share/locale/l10n/as
|
which is good, no i686 anywhere
but the symlinks are still broken...
i just did
gentoo bin # ln -s i486-pc-linux-gnu-ar ar
gentoo bin # ln -s i486-pc-linux-gnu-as as
gentoo bin # ln -s i486-pc-linux-gnu-ld ld
...
binutils has compiled, now i'm compiling gcc |
