mesa3d uses very big switch statements, which causes the build to fail on m68k, beause the offsets there are only 16-bit. We fix that by using -mlong-jump-table-offsets on m68k, to use 32-bit offsets for switch statements, but this is only available starting with gcc 7 [0] [1]. Fixes: http://autobuild.buildroot.net/results/60c4653c2a93125edbdd0beb43cd47301643464a/ Note: we have two packages that select mesa3d, but: package/intel-mediadriver/ -> already depends on x86_64, so implies !m68k package/x11r7/xdriver_xf86-video-imx-viv/ -> imx is an ARM, but xdriver_xf86-video-imx-viv is missing a depends on BR2_arm (although the comments do have that dependency). However, it depends on other imx related packages, and they depend on either arm or aarch64, so that implies !m68k. As such, we do not need to propagate that new dependency.

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