[gentoo-dev] gcc3 rebuilds and hints :

[Spider]

heres a script that lists all the packages that will require to be
rebuilt once you change your profile to gcc3 instead of gcc


it lost some formatting here, so you'll have to make sure its working
before using it. 


emerge gentoolkit first :)

//Spider



#!/bin/bash
# highly unoptimized.
# First, find all executables that link to c++ libraries


find / -type f -perm +o+x  | while read FILE;do ldd "${FILE}" |grep
"libstdc++" - >/dev/null && echo ${FILE} >>/root/REBUILD.files;echo
${FILE}; done

# then, get the package they belong to.
cat /root/REBUILD.files |while read FILE; do qpkg -nc -f "${FILE}"
>>/root/REBUILD.packs;echo ${FILE};done

#Now sort the list and get only relevant issues
cat /root/REBUILD.packs |sort |uniq >/root/REBUILD.packs.new
