The /usr/lib64/ccache is added in PATH by /etc/profile.d/ccache.sh when ccache is installed on Fedora host, the issue disappears if one of the following changes is done.
1. 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. Should I open a Bugzilla ticket to track it?
$ echo $PATH
/usr/lib64/qt-3.3/bin:/usr/lib64/ccache:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/bjsimics/.local/bin:/home/bjsimics/bin
which gcc
/usr/lib64/ccache/gcc
$ gcc -v

/usr/lib64/ccache is unusual why do you have it in path and if you really need it add it after all other paths. Check your env first

[Luo Zhenhua-B19537] gcc can't be found after sourcing the SDK env script. but the /usr/bin is in the PATH env variable.
