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/fabrice/buildroot/output/host/mips-buildroot-linux-gnu/sysroot/usr/include/features.h:394, from ../include/libcgroup/error.h:9, from ../include/libcgroup.h:21, from log.c:15: /home/fabrice/buildroot/output/host/mips-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" | ^~~~~ Indeed, this LFS workaround is there since the addition of the package in commitff7191c12eand is only needed to fix a build failure with the old codesourcery-arm toolchain from 2014 which uses glibc < 2.23. as glibc 2.23 was released in February 2016: https://sourceware.org/glibc/wiki/Release/2.23, drop this workaround as already done for libselinux in commitc1fa9bc2f7. A follow-up patch will also drop codesourcery-arm toolchain.

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.
