Since version 0.15.0, qemu has an optional dependency to opengl:20ff075bb3Since version 2.4, libepoxy is also needed to enable opengl:dcf30025c3As a result if libepoxy is built before qemu, opengl support will be detected (see config.log): OpenGL support yes OpenGL dmabufs yes This will raise the failures in milkymist-tmu2: hw/display/milkymist-tmu2.c:35:22: fatal error: X11/Xlib.h: No such file or directory or in sdl2: CC /home/peko/autobuild/instance-0/output/targetui/sdl2-2d.o In file included from /home/peko/autobuild/instance-0/output/build/qemu-2.12.1/include/ui/egl-context.h:5:0, from ui/egl-context.c:3: /home/peko/autobuild/instance-0/output/build/qemu-2.12.1/include/ui/egl-helpers.h:45:55: error: unknown type name 'Window'; did you mean 'minor'? or in translate-a64: /accts/mlweber1/scripts/instance-3/output/build/qemu-2.12.1/target/arm/translate-a64.c: In function 'handle_shri_with_rndacc': /accts/mlweber1/scripts/instance-3/output/build/qemu-2.12.1/target/arm/translate-a64.c:7000:28: warning: 'tcg_src_hi' may be used uninitialized in this function [-Wmaybe-uninitialized] tcg_gen_mov_i64(tcg_src, tcg_src_hi); ^ ../ui/gtk-egl.o: In function `gd_egl_init': /accts/mlweber1/scripts/instance-3/output/build/qemu-2.12.1/ui/gtk-egl.c:52: undefined reference to `gdk_x11_window_get_xid' So, for the time being, disable opengl as done in xen since commit13c6754f3c.

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
