In preparation for the upgrade of glibc to version 2.39, we need to backport some gcc patches. Indeed glibc 2.39 drops libcrypt, causing a build failure of libsanitizer (part of gcc) as it has code to intercept crypt() and crypt_r() calls. This has been fixed in gcc master, but we need to backport the fix for gcc 11.x, 12.x and 13.x. gcc 8.x doesn't need to be fixed because (1) its libsanitizer does not have an interceptor for crypt()/crypt_r() and (2) we only allow gcc 8.x for PowerPC SPE, for which we only support uClibc-ng, so this issue with crypt/crypt_r going away from glibc is not relevant.

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
