    Why Copied Yocto Cross Toolchain Not Work

    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
    ELF��4H�
     4  (44�4�  TT�T���ܝ
                         ܝ
                                �
                                 lz��

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

    3 solution

    install it by using the SDK shell.
