Missing bison error
-------------------

.. code-block:: guess

[ 1% 322/20069] Yacc: checkpolicy <= external/selinux/checkpolicy/policy_parse.y
FAILED: /bin/bash -c "prebuilts/misc/linux-x86/bison/bison -d -v --defines=/home/builder/workdir/out/host/linux-x86/obj/EXECUTABLES/checkpolicy_intermediates/policy_parse.h -o /home/builder/workdir/out/host/linux-x86/obj/EXECUTABLES/checkpolicy_intermediates/policy_parse.c external/selinux/checkpolicy/policy_parse.y"
/bin/bash: prebuilts/misc/linux-x86/bison/bison: No such file or directory

The error message is very misleading here. The issue stems from the bison shipped with ``halium-7.1`` at ``prebuilts/misc/linux-x86/bison/bison`` being 32-bit only, with the host system lacking 32-bit compatibility.

The fix is to install 32-bit support for Ubuntu via:

.. code-block:: guess

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
