There are three things you need to know in Redox build system to achieve full offline build system.
The first thing that you need to do is fetch as many package sources that you might want to download before going offline. I recommend following these steps:
- Set
CONFIG_NAME=ci. It will match to all packages proven to build correctly - Run
make fetch. It will download all of them without building it
After fetch is done you can revert CONFIG_NAME to a kind of image you wish to build.
