    3
    
    
    
Please follow the below steps to complete AI simple test.





    4
    
    
    





    5
    
    
    
(1)Download the test APP package linux_sample_2019_10_25_UTC.rar from





    6
    
    
    





    7
    
    
    
https://onlinedcc.innocomm.com/seeddms/out/out.ViewFolder.php?folderid=1464&showtree=1





    8
    
    
    





    9
    
    
    





    10
    
    
    
(2)Extract linux_sample_2019_10_25_UTC.rar you will have folder named linux_example





    11
    
    
    





    12
    
    
    
(3)After fully built SB50 Yocto linux, we'll export toolchain path as below:





    13
    
    
    





    14
    
    
    
   This is my compile environment for your reference:





    15
    
    
    





    16
    
    
    
<pre>





    17

export SDKTARGETSYSROOT="//home/inncomm/root/sb50/build/tmp/work/aarch64-poky-linux/apunn/1.0-r0/recipe-sysroot"





    19
    
    
    
export OECORE_NATIVE_SYSROOT="/home/inncomm/root/sb50/build/tmp/work/aarch64-poky-linux/apunn/1.0-r0/recipe-sysroot-native"





    20
    
    
    
export CXX="aarch64-poky-linux-clang++ --sysroot=$SDKTARGETSYSROOT"





    21
    
    
    
export CC="aarch64-poky-linux-clang --sysroot=$SDKTARGETSYSROOT"





    22
    
    
    
</pre>





    23
    
    
    





    24
    
    
    
(4)make makefile under linux_example





    25
    
    
    
<pre>





    26
    
    
    
   (a) Modify linux_example/CMakeLists.txt





    27
    
    
    
       SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")





    28
    
    
    





    29
    
    
    
   (b) If you meet lack of libcxx.so





    30
    
    
    
       Please add extract and copy the attached lib_1.rar to linux_example/ 





    31
    
    
    
       And add the below to linux_example/CMakeLists.txt





    32
    
    
    
       LINK_LIBRARIES("${CMAKE_CURRENT_LIST_DIR}/lib_1/aarch64-poky-linux/libc++.so.1")





    33
    
    
    
       LINK_LIBRARIES("${CMAKE_CURRENT_LIST_DIR}/lib_1/aarch64-poky-linux/libc++abi.so.1")





    34
    
    
    





    35
    
    
    
   (c)Move to /linux_example
