While fixing a build error ../src/egl/drivers/dri2/platform_x11.c: In function 'dri2_x11_get_msc_rate': ../src/egl/drivers/dri2/platform_x11.c:1229:44: error: 'struct dri2_egl_display' has no member named 'screen_resources' with this defconfig: BR2_x86_64=y BR2_TOOLCHAIN_BUILDROOT_CXX=y BR2_PACKAGE_MESA3D=y BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_IRIS=y BR2_PACKAGE_MESA3D_OPENGL_GLX=y BR2_PACKAGE_MESA3D_OPENGL_EGL=y BR2_PACKAGE_MESA3D_OPENGL_ES=y BR2_PACKAGE_XORG7=y (crocus and i915 drivers are also affected) it turns out that we can assume the need for dri3 support when X.org is enabled as a hard depen- dency even if mesa3d's configure does not throw errors when missing, like for the Intel drivers. Before this patch these Config.in options were used: config BR2_PACKAGE_MESA3D_DRI3 select BR2_PACKAGE_XLIB_LIBXSHMFENCE select BR2_PACKAGE_MESA3D_DRI3 if BR2_PACKAGE_XORG7 which can be translated into: select BR2_PACKAGE_XLIB_LIBXSHMFENCE if BR2_PACKAGE_XORG7 and used at option BR2_PACKAGE_MESA3D_DRIVER. Configure option -Ddri3=enabled is passed to mesa3d when at least one driver is enabled along with X.org: ifeq ($(BR2_PACKAGE_MESA3D_DRIVER)$(BR2_PACKAGE_XORG7),yy) Signed-off-by: Bernd Kuhls <bernd@kuhls.net> Signed-off-by: Arnout Vandecappelle <arnout@mind.be>
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.
