Sir @kundfl , i found the solution one of ur posts as mention below, because for same problem
compiz:/opt/quartus/linux/libstdc++.so.6 version GLIBCX_3.4.15 not found required by compiz, but how to get gcc-4.6.2 and how to compile Compile gcc-4.6.2 with --prefix=/usr/local/gcc462/, plz tel me step by step procedure.
Solution : Compile gcc-4.6.2 with --prefix=/usr/local/gcc462/,
copy libstdc++.so.6.0.16 to /usr/lib64/,
and make a new symlink libstdc++.so.6 to libstdc++.so.6.0.16
Or grap libstdc++.so.6.0.16 from "libstdc++6_4.6.2-7_amd64.deb"
http://ftp.de.debian.org/debian/pool....2-7_amd64.deb
The package can be unpacked with 'ar -x <package> && tar xvf data.tar.gz'.
Thnks,
Alex.
