Virtualbox image ready for development somewhere?

[kev]

Hi,

Anyone made a virtualbox ready image for development? Or is there a script for debian or other to get all the requirements?

Thanks!

For Debian 9 -- Edit: base install, no graphical environment, allow at least 32 GB, 64 GB "expandable" is safer.

sudo apt install build-essential git gitk libncurses5-dev gawk unzip wget curl ccache rsync zlib1g-dev

Edit: gitk probably isn't required, but I find it so helpful that it's included.

Totally optional, though might be helpful for current versions of git format-patch and git send-email
(assuming here that overwriting /etc/apt/sources.list.d/backports.list is OK)

echo "deb http://ftp.debian.org/debian stretch-backports main" | sudo tee /etc/apt/sources.list.d/backports.list
sudo apt update
sudo apt -t stretch-backports upgrade git
sudo apt autoremove   # Optional to clean up disk space
sudo apt autoclean    # Optional to clean up disk space

If you want to use Alpine Linux (quite quick to pick up upstream compared to Debian) and usually a smaller in general

[solved] Cmake build error (and wolfssl error in alpine)

Default install of extended (no docker image) apk add git build-base bash ncurses-dev perl tar findutils patch coreutils gawk grep unzip bzip2 wget python2-dev linux-headers curl diffutils bsd-compat-headers less diffutils Create non root user cd openwrt make menuconfig .... Works great for me, no idea if 18.X works however

It does feel snappier than my Debian install but it might be placebo FWIW

ccache isn't needed at all and rsync would be optional

[jeff]

I speed my work with

CONFIG_DEVEL=y
CONFIG_BUILD_LOG=y
CONFIG_CCACHE=y
CONFIG_DOWNLOAD_FOLDER="/home/jeff/devel/openwrt_dl"

the last since I have multiple build trees going. But yes, ccache isn't required.

Minimal distro to build openwrt image

For the (newer) OpenWrt buildslaves we also use a base Debian 9 Docker image with the following packages: RUN apt-get update && \ apt-get install -y \ pwgen \ locales \ buildbot-slave \ build-essential \ git-core \ subversion \ libncurses5-dev \ gawk \ unzip \ wget \ curl \ ccache \ rsync This can be trimmed down some more since pwgen, buildbot-slave, ccache and rsync are not really required to build …

I've never found anything that I build to require subversion, but the buildbots try to build every available package.

@jeff since I had Debian, I tried to set it up your way. This was my first time and overall it went pretty well. Just finished compiling, will test with sysupgrade tomorrow!

@diizzy thanks for all the tips, I'll keep that in mind for future builds.

Overall, building in a VM with 4 cores was pretty slow, but I just read in the FAQ I can tell make to use multithreads (jobs), will try that next time :

make -j 5
