 |
|
This may be a silly problem, but it is stupid o'clock. My alpha stopped booting sometime in the last week, and now that I have something off the live cd, glibc has been masked, and wants to downgrade. Seeing as how the machine currently doesn't boot, I'd like to try downgrading, but portage refuses to let me do so. Any easy way to do this?

Portage says true. Thre is a way to downgrade glibc, but this would brake your system.
Copy all your system files, then use this script:
| Code: |
#!/bin/bash
CBUILD=$(portageq envvar CHOST)
PORTAGE_CONFIGROOT="/"
if [[ "$1" == "--root" ]] ; then
ROOT="$2"
shift 2
else
ROOT="$SYSROOT"
fi
export CBUILD PORTAGE_CONFIGROOT ROOT
LDFLAGS="-l/usr/armv5tel-gnueabi-linux-gnu/usr/lib/ -l/usr/armv5tel-gnueabi-linux-gnu/lib/ -l/pda/lib -l/pda/usr/lib ${LDFLAGS}"
emerge $*
|
xmerge --root "path where you copied your system files" -C glibc
xmerge --root "path where you copied your system files" =glibc-needed glibc version
After this that copy would contain older glibc, however it may (must) not work. But using the same script you car rebuild world with older glibc. |
