Hello,

I build RDKB RPI image and flash the image to RPI device. I want to enable ldd on the RPI, to quick identify the libraries which the binary linked.

Can you help to share how to enable ldd? Thank you very much!

    Hi Tang Heming ,

    Please add ldd package to packaging file .

    For reference check the below code

    diff --git a/recipes-core/packagegroups/packagegroup-rdk-ccsp-broadband.bbappend b/recipes-core/packagegroups/packagegroup-rdk-ccsp-broadband.bbappend
    index 87a66a2..965494b 100644
    --- a/recipes-core/packagegroups/packagegroup-rdk-ccsp-broadband.bbappend
    +++ b/recipes-core/packagegroups/packagegroup-rdk-ccsp-broadband.bbappend
    @@ -6,6 +6,7 @@ RDEPENDS_packagegroup-rdk-ccsp-broadband_append = "\
         libseshat \
         notify-comp \
         start-parodus \
    +    ldd \
         \
     "

    Then Compile and flash the image . ldd should be available
