Hi,
backup done!
now...
gcc-4.8.3 is installed, gcc-config points to the new compiler, the
environment is updated (I logged out and in again) and I checked
/etc/env.d/04gcc-armv7a-hardfloat-linux-gnueabi for using the new
compiler. So everything is fine...except...
If I would remove the old compiler now, my system would again be
broken.
I run the following little loop (zsh) "(.)" means: "only files"):
for i in /sbin/*(.) /bin/*(.) /usr/sbin/*(.) /usr/bin/*(.)
do
ldd $i | grep -q -s
'/usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.7.3/libgcc_s.so.1'
if [[ "$?" == "0" ]] ; then echo $i >> /tmp/gccfiles6.txt ; fi
done
I did find
1033
executables still linked against
/usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.7.3/libgcc_s.so.1
and may be there are more being linked against other libs of the old
compiler.
Should I rebuild Gentoo?
This would take a very very long time on this little system...
How to proceed now?
Best
Meino
