libv4l has some really special code that is built explicitly with _FILE_OFFSET_BITS=32, which doesn't work with _TIME_BITS=64, causing build failures when BR2_TIME_BITS_64=y. This build issue has been fixed upstream. While how the upstream patch exactly works is unclear, it's the patch that upstream has decided to implement to resolve the build issue, so we simply backport it. The issue exists since at least upstream commit 99f245f5e2826c7ae3ac8de530bc2fbd906eb62b, which was merged in v4l-utils 1.26.0.

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.
