float128 is now required on powerpc64le with glibc >= 2.26 toolchains. Fixes: running configure fragment for sysdeps/gnu running configure fragment for sysdeps/powerpc/powerpc64le checking if [...]powerpc64le-buildroot-linux-gnu-gcc supports binary128 floating point type... no checking if the target machine is at least POWER8... yes configure: error: *** binary128 floating point type (GCC >= 6.2) is required on powerpc64le. In order to prepare the glibc bump to this version, we enable binary128 floating point in gcc. This require at least gcc >= 6.2. Disable gcc 4.x and 5.x for internal 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 Freenode IRC.
