UPDATE: Sorry for the broken tabs/spaces in the Makefile above. I don't know how to fix this here, you'll have to fix it in the editor of your choice.

I was not able to compile any recent adb for arm on a Raspberry Pi so far, even after upgrading to Raspbian 10/buster which offers gcc 8.3.0. It also comes with adb v1.0.39, 1:8.1.0+r23-5. And to my surprise, Raspbian 11/bullseye actually includes adb v1.0.41, 28.0.2-debian Even better, bullseye is also available for arm64 now!

1. adb-compile-env-setup.sh

    #!/bin/bash
   
    # some steps found here: http://android.serverbox.ch/?p=1217
   
    sudo apt-get install libssl-dev
   
    mkdir ~/adb-dev/5.1.1
    cd ~/adb-dev/5.1.1
   
    mkdir system
    mkdir external
   
    cd system/                
    git clone -b android-5.1.1_r1 https://android.googlesource.com/platform/system/core
    git clone -b android-5.1.1_r1 https://android.googlesource.com/platform/system/extras

    cd ../system/core/adb
   
    cp ~/adb-dev/Makefile .
   
    echo "Ready to hit *make* now and pray?"
    read -rsp $'Press any key to continue...\n' -n1 key

Sp lets compile adb on the Raspberry Pi itself - without any cross-compiling madness. It was actually easier than you'd think. All you should need is git and gcc (and the package libssl-dev, which is installed by the bash script).
