Remove /usr/lib64/ccache from PATH 2. Move /usr/lib64/ccache after /usr/bin in PATH 3. Set CCACHE_PATH equals to PATH 4. Unset CCACHE_PATH Another observation, before sourcing environment-setup-<core>-poky-linux, gcc can be found even if /usr/lib64/ccache is in prepend to PATH, but after sourcing the environment-setup-<core>-poky-linux script, the gcc can’t be found, this should be a bug of the environment-setup-<core>-poky-linux script.

Ideally you should just uninstall ccache from your build host.
