[yocto] Failed to cross compile kernel with Yocto toolchain

Wed Jun 29 18:54:52 PDT 2016

I think you mean /usr/lib64/ccache/gcc instead of /usr/lib64/gcc, it is a valid link. 

$ source /opt/poky/2.1+snapshot/environment-setup-ppce500mc-poky-linux 
$ which gcc
/usr/lib64/ccache/gcc
$ 
$ ls -l /usr/lib64/ccache/gcc
lrwxrwxrwx 1 root root 16 Jun 29 18:22 /usr/lib64/ccache/gcc -> ../../bin/ccache
$ ls -l /usr/bin/ccache 
-rwxr-xr-x 1 root root 128584 Jan 26 14:58 /usr/bin/ccache
$ 

Best Regards,

Zhenhua
