GCC 4.9.x requires an old version of ISL to support graphite, and this old version of ISL is not sufficient to support graphite in modern GCC versions. Since GCC 4.9.x is getting older, and to keep things simple, we stop supporting graphite on old GCC < 5.x. This way, we will be able to bump ISL to a version that is suitable for modern GCC versions. In addition, this allows to drop the dependency on cloog, which was only needed for GCC 4.9.

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
