    Hi,

    I have failed compile and install the edgeai-gst-plugins, edgeai-tiovx-modules and apps_cpp demos , some errors for libtivision_apps.so，how can I fix it ?

    Hello,

    Apologies for the late response. From the log that has been posted, it seems like libdlr.so, which contains the functions required by libtivision_apps.so such as 'GetDLRInputSizeDim', is not being loaded.

    Could you do two things for me:

    • Post the full log when running setup_scripts.sh so that I can see if the issue is caused by a prior step in the setup script
    • Run "ls /usr/lib/gcc/aarch64-linux/9.2.1/../../.. | grep libdlr" to make sure that libdlr.so exists

    Regards,

    Takuma

    Hello,

    For others that may find this thread, this error may come up due to an issue with /opt/edge_ai_apps/init_script.sh.

    If manually running this script fails to complete, try commenting this line and rerun as a temporary workaround: #udhcpc -i wlp1s0 > /dev/null 2>&1

    When a WiFi card is connected and the board is in AP mode, this line of code may hang. This causes the rest of the init_script.sh fail to run and the symbolic link /usr/lib/libdlr.so is not created.

    Regards,

    Takuma
