env.sh in SDK is a symbol link that should points to the default tune's environment-seup file, so that WB can pick it up correctly. However in cav-octeon3's SDK, the link is created as env.sh -> environment-setup-octeon3-n32-wrs-linux while it should be env.sh -> environment-setup-octeon3-n32-wrs-linux-gnun32
wrlinux/configure --enable-board=cav-octeon3 --enable-rootfs=glibc-small --enable-kernel=standard make export-sdk # install SDK ls -l env.sh
