    This is the output on voxl cross.but on voxl2 we couldn't run the command for opkg.
    Can you please tell the equivalent command for voxl 2 ?

    Can I double check. Did you run ./install_build_deps.sh before trying to build?

    If building for a VOXL 2 the full command would be ./install_build_deps.sh qrb5165 stable

    If we are building it for voxlcam, what should be used?

    If we use ./install_build_deps.sh apq8096 stable, we get the error,

    @Nishkala you can instead use ./install_build_deps.sh apq8096 sdk-0.8

    @Matthew-Booker Thanks a lot!

    What works for me is:

    voxl-cross:~/voxl-mapper(master)(0.0.7)$ ./install_build_deps.sh apq8096 sdk-0.8
    voxl-cross:~/voxl-mapper(master)(0.0.7)$ ./build.sh apq8096
    voxl-cross:~/voxl-mapper(master)(0.0.7)$ ./make_package.sh ipk
    scp voxl-mapper_0.0.7.ipk root@10.0.1.10:

    On voxl 1 board, I added arm64 7 to /etc/opkg/arch.conf
    voxl:~$ voxl-configure-opkg dev
    opkg install --force-reinstall --force-downgrade --force-depends --force-overwrite voxl-mapper_0.0.7.ipk

    Then everything seems to work so far!

    @Matthew-Booker However, when I try to save the mesh from the portal, in my compiled version, I get this symbol not found error. Any ideas why it can not find this function and how to fix it? Many thanks in advance.

    @Arjun-Jain Looks like a mismatch in the voxl-voxblox version. Since you've already configured opkg you should just be able to run opkg install voxl-voxblox and it should work.

    @Matthew-Booker How to do the same on voxl2

    I tried the below commands
    voxl-cross:~/voxl-mapper(master)(0.0.7)$ ./install_build_deps.sh apq8096 sdk-0.8
    voxl-cross:~/voxl-mapper(master)(0.0.7)$ ./build.sh apq8096
    voxl-cross:~/voxl-mapper(master)(0.0.7)$ ./make_package.sh
    voxl-cross:~/voxl-mapper(master)(0.0.7)$ ./deploy_to_voxl.sh

    On the voxl2 board
    voxl2:/$ voxl-configure-pkg-manager
    Chose sdk 0.8
    voxl2:/$ apt update
    voxl2:/$ voxl-mapper

    I got the below error
    '

    @Nishkala When you build for voxl2 you need to use qrb5165 not apq8096 so the full command would be:
    ./install_build_deps.sh qrb5165 sdk-0.8
    ./build.sh qrb5165
    ./make_package.sh

    @Matthew-Booker
    I ran the below commands on voxl cross:
    ./install_build_deps.sh qrb5165 sdk-0.8
    ./build.sh qrb5165
    ./make_package.sh
    ./deploy_to_voxl.sh

    I ran voxl-mapper after this on the board and got the error 'voxl-mapper: symbol lookup error: voxl-mapper: undefined symbol: _ZNK7voxblox5LayerINS_9EsdfVoxelEE10saveToFileENSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEb
    '

    I wanted to add arm64 to /etc/opkg/arch.conf but voxl2 uses apt. How to solve the above issue?

    That error occurs when theres a voxl-voxblox version mismatch. The version of voxl-voxblox on your voxl2 is older. On your voxl2 if you run the following it should update

    apt install voxl-voxblox
