An user is allowed to install the toolchain in the default location (/opt/poky/1.2+snapshot) only by running it it with sudo, like: [alex@alex-v toolchain]$ sudo ./poky-eglibc-x86_64-i586-toolchain-gmae-1.2+snapshot-20120916.sh A nice improvement would be to have a sudo passwd prompt during installation if the user doesn't run it with sudo.
