Do not remove _FILE_OFFSET_BITS=64 from CFLAGS and CPPFLAGS to avoid the following build failure with BR2_TIME_BITS_64 raised since commit3c427c6472: In file included from /home/autobuild/autobuild/instance-9/output-1/per-package/libselinux/host/mipsel-buildroot-linux-gnu/sysroot/usr/include/features.h:394, from /home/autobuild/autobuild/instance-9/output-1/per-package/libselinux/host/mipsel-buildroot-linux-gnu/sysroot/usr/include/bits/libc-header-start.h:33, from /home/autobuild/autobuild/instance-9/output-1/per-package/libselinux/host/mipsel-buildroot-linux-gnu/sysroot/usr/include/stdint.h:26, from /home/autobuild/autobuild/instance-9/output-1/per-package/libselinux/host/lib/gcc/mipsel-buildroot-linux-gnu/12.3.0/include/stdint.h:9, from ../include/selinux/avc.h:9, from avc.c:10: /home/autobuild/autobuild/instance-9/output-1/per-package/libselinux/host/mipsel-buildroot-linux-gnu/sysroot/usr/include/features-time64.h:26:5: error: #error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64" 26 | # error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64" | ^~~~~ This LFS workaround for glibc < 2.23 was added in 2016 by commitebcca24c95and is probably not needed anymore as glibc 2.23 was released in February 2016: https://sourceware.org/glibc/wiki/Release/2.23 Fixes: - http://autobuild.buildroot.org/results/d85c81f87adf3a5945fa369bcec233e6def2ed12 Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> Signed-off-by: Arnout Vandecappelle <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 OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
