Pass -Werror=shadow in args of cc.compiles in meson.build otherwise test will always succeed, causing -Werror=shadow to be passed, even on older gcc versions. GCC 4.8 changed the behaviour of -Werror=shadow to no longer complain about local variable declariations shadowing functions, which systemd has. From the changelog: The option -Wshadow no longer warns if a declaration shadows a function declaration, unless the former declares a function or pointer to function, because this is a common and valid case in real-world code. https://www.gnu.org/software/gcc/gcc-4.8/changes.html Fixes: - http://autobuild.buildroot.org/results/ffd71c473d3b29618c18cd2e04705370266696f2 [Peter: extend commit message, add gcc 4.8 link] Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
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.
