Currently glibc 2.30 is build by default with Werror enabled but it has only been tested with compiler version available at the time of the release [1] (gcc 6.2 up to gcc 9.2.1). It's recommended to use those version with glibc 2.30. For the same reason why we remove Werror in packages's compiler flags. Building with Werror is not bulletproof when we start using a newer compiler that introduce new warnings. This is the case here with gcc 10, as reported by Yegor Yefremov [2]. Fixing compiler warnings would require backporting many patches [3] not even backported by Glibc maintainers to the 2.30 stable branch. Instead, disable Werror by using --disable-werror. Most (if not all) gcc 10 warnings will be fixed with Glibc 2.31.

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
