Virtualbox image ready for development somewhere?

[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.
