Error while following DRIVE PX2 ROS CROSS COMPILATION instructions

Autonomous Vehicles DRIVE PX 2 General

I followed the instructions as mentioned in the FAQ (DRIVE PX2 ROS CROSS COMPILATION), but I am getting an error after invoking cross-compilation command
sudo ./ros-bare-bone-src/src/catkin/bin/catkin_make_isolated
–install -DCMAKE_BUILD_TYPE=Release
–source ros-bare-bone-src/src
-DCMAKE_TOOLCHAIN_FILE=/home/nvidiapx2/modifiedToolchainRos/toolchainRos.cmake
-DCATKIN_ENABLE_TESTING=false

Dear swetha.rao,

This seems like a library missing problem.

Would you try to run the steps below?
$ sudo mkdir /lib/aarch64-linux-gnu
$ sudo mkdir /tmp/ros-cc-overlayfs
$ sudo mount -t overlay -o lowerdir=/lib/aarch64-linux-gnu,upperdir=/lib/aarch64-linux-gnu,workdir=/tmp/ros-cc-overlayfs overlay /lib/aarch64-linux-gnu

    Dear SteveNV,

    I tried the mentioned steps, but I am still getting the same error, but weirder. All the words are displayed twice as shown below,

    …
    The .so files mentioned in the error message exist in the targetfs/usr/lib/aarch64-linux-gnu/ folder, I don’t know why the files are not getting linked.
    Is there a way to try everything again by uninstalling the packages previously installed. Or can I install the ubuntu-xenial arm64 root file system again by running the .run files in DRIVE 5.0 Linux release?
