In order to not have to define all architecture bitness variants in src/LibSupport.h to conditionally define RADIX_BITS, a patch was created to depend on LONG_BIT being defined via limits.h For glibc, LONG_BIT is behind a _XOPEN_SOURCE define guard so patch the makefile to define this macro as well as _DEFAULT_SOURCE. Defining _XOPEN_SOURCE requires _DEFAULT_SOURCE to be explicitly defined for builds to succeed as it is no longer impliclty defined when _XOPEN_SOURCE is defined.

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.
