meson allows to force all features set to "auto" to default to disabled except if explicitly enabled via the auto_features argument, c.f. https://mesonbuild.com/Build-options.html#features """ If the value of a feature option is set to auto, that value is overridden by the global auto_features option (which defaults to auto). This is intended to be used by packagers who want to have full control on which dependencies are required and which are disabled, and not rely on build-deps being installed (at the right version) to get a feature enabled. """ The only auto feature that we hadn't disabled explicitly is the gstreamer plugin. It is however expected that this wasn't a mistake as the dependencies for the gstreamer pluging wouldn't have been met thanks to the explicit LIBCAMERA_DEPENDENCIES we have based on the presence of the gstreamer symbols in the global config. This should make it less likely for future releases of libcamera to regress in terms of reproducibility because of "auto" features (though changes from "auto" to "enabled" wouldn't be caught and would be susceptible to race conditions with their dependencies in case they aren't properly specified and built after libcamera is).

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
