build kernel - /bin/sh: 1: bison: not found

[tswaehn]

I created a fresh debian x64 VM on virtualbox, cloned the rpi23-gen-image and tried to create an image for RPI3 stretch (all settings default)

(first minor issue was, that Qemu was not installed automatically - fixed that manually)

but second issue is the one below:

make -C /home/siri/tmp/rpi23-gen-image/images/stretch/build/chroot/usr/src/linux ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- bcm2709_defconfig
make: Entering directory '/home/siri/tmp/rpi23-gen-image/images/stretch/build/chroot/usr/src/linux'

looks like manual install of bison solves the job

sudo apt-get install bison

Actually flex was missing too

sudo apt-get install flex

Question: is it expected to install these manually or shall we check and install automatically?

[tswaehn]

if needed, we could modify this line

REQUIRED_PACKAGES="debootstrap debian-archive-keyring qemu-user-static binfmt-support dosfstools rsync bmap-tools whois git bc psmisc dbus sudo"

and add flex,bison

Kernel package build dependencies change over time as the kernel developers change the configuration. Make sure you have deb-src entries in sources.list and use apt-get build-dep KERNEL where KERNEL is the name of a recent kernel package.

I just did setup a fresh debian and installed all "kernel depencies" as per you suggetion

apt-get build-dep linux-image-XXXX

and it did the trick.

However, for me speaking that step is missing in the README.md

Is there a general way of adding this to the README.md ?

it is unexpected. If flexand bisonare now required for default kernel, add it to the REQUIRED_PACKAGES. Last time i checked only nexmonand ubootoption required those packages.

Could you create a pull request?

Thanks/Danke!
