Like git which can have submodules, subversion can have externals. The default behaviour for subversion is to retrieve all the externals, unless told otherwise. For some repositories, the externals may be huge (e.g. a dataset or some assets) and may not be required for building the package. In such a case, retrieving the externals is both a waste of network bandwitdh and time, and a waste of disk storage. Like for git submodules and git lfs, add an option that packages can set to specify whether they want externals or not. Since we've so far been retrieving externals, we keep that the default, and packages can opt-out (rather than the opt-in for git submodules or git lfs). We must only set it when the package is actually hosted on svn, to avoid passing -r when the package is not hosted by svn; otherwise, -r would also be passed e.g. to a git-hosted package, triggering the download of git submodules even when they are not requested. We need to do so, because we have a default value, which we usually do not have in other download options. Signed-off-by: Yann E.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
