When the host uses glibc 2.26 or newer, Flex will try to use the newly-introduced reallocarray() function, but as it would not define _GNU_SOURCE a segmentation fault would occur later on due to the compiler assumming that the function is implicitly defined. This issue manifests itself due to a crash of "stage1flex" during the Flex bootstrap: ./stage1flex -o stage1scan.c ./scan.l make[2]: *** [Makefile:1725: stage1scan.c] Segmentation fault (core dumped) This imports the patch from the upstream Git repository, and adds flags in the .mk file to rebuild the Autotools scripts and support files. Due to the latter, the patch to disable the documentation is changed so it modifies the .am file instead. Signed-off-by: Adrian Perez de Castro <aperez@igalia.com> [Arnout: - Add Adrian's Sob and upstream ref to new patch; - Keep patch 1 as patch 1; - Keep Vicente as author of path 1; - Add reason for autoreconf in a comment.] Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> |

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
