/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.
$ source /opt/poky/2.1+snapshot/environment-setup-ppce500mc-poky-linux
$ echo $PATH
/opt/poky/2.1+snapshot/sysroots/x86_64-pokysdk-linux/usr/bin:/opt/poky/2.1+snapshot/sysroots/x86_64-pokysdk-linux/usr/sbin:/opt/poky/2.1+snapshot/sysroots/x86_64-pokysdk-linux/bin:/opt/poky/2.1+snapshot/sysroots/x86_64-pokysdk-linux/sbin:/opt/poky/2.1+snapshot/sysroots/x86_64-pokysdk-linux/usr/bin/../x86_64-pokysdk-linux/bin:/opt/poky/2.1+snapshot/sysroots/x86_64-pokysdk-linux/usr/bin/powerpc-poky-linux:/opt/poky/2.1+snapshot/sysroots/x86_64-pokysdk-linux/usr/bin/powerpc-poky-linux-uclibc:/opt/poky/2.1+snapshot/sysroots/x86_64-pokysdk-linux/usr/bin/powerpc-poky-linux-musl:/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
