Although BR2_DL_DIR is indeed a site-local setting, which does not actually define the target system, we've had it in the tree for a long time now, and people have been depending on it for a variety of use-cases. Furthermore, BR2_DL_DIR is far from the only such site-local setting, BR2_CCACHE_DIR springs to mind, and in the less-obvious category, we can also find BR2_JLEVEL, but also BR2_WGET, BR2_SVN, BR2_GIT et al. as they may be tweaked to set the timeout, number of retries or so on to work around stupid proxies. But of course, the most local site-local setting is probably BR2_PACKAGE_OVERRIDE_FILE, with its default value being explicitly just 'local.mk'. Ideally, we would like to have a clear separation between the configuration that actually defines the target system on one hand, and the site-local settings that drive and control how the build is performed, on the other hand. This is by far a much bigger endeavour than just dropping BR2_DL_DIR from the saved defconfig. This reverts commit36edacce9c(adapted to keep the fix from1a7873ec98). Closes: #13291 Note: thanks to Thomas; some phrasing above was borrowed from a discussion with him. 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 Freenode IRC.
