1 problem description

When I copied yocto cross toolchain from colleague, and test it as below:

$ cd i686-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi$
$ ./arm-poky-linux-gnueabi-gcc
bash: ./arm-poky-linux-gnueabi-gcc: No such file or directory

2 analysis

2.1 install source check

My colleague installed the toolchain by using his generated SDK shell.

poky-glibc-i686-fsl-image-gui-cortexa7hf-vfp-neon-toolchain-1.8.sh

2.2 cross tool header check

$ head -1 ./arm-poky-linux-gnueabi-gcc

We can see the cross tool's header contains my colleague's cross tool path info, which not exist on my machine!!!

install it by using the SDK shell.
