yocto-L4.1.15_1.2.0 ，Wayland/weston 没有启动成功

[zhangzy]

在rootfs 的/etc/init.d 目录有个weston文件，里面会启动weston :"openvt -s weston -- $OPTARGS
", 从终端log看weston 没有启动起来，没有如下log 打出：

[01:37:43.969] weston 1.9.0

[01:37:43.969] OS: Linux, 4.1.15+, #29 SMP PREEMPT Fri Dec 30 14:20:22 CST 2016, armv7l

在这个脚本里直接运行 自带的 Wayland 例子程序，也会报错。

是什么原因呢？

Hi,

Open the file:
 <YOCTO_DIR>/sources/meta-fsl-bsp-release/imx/meta-bsp/recipes-graphics/wayland/weston_1.9.0.bb

DEPENDS = "libxkbcommon gdk-pixbuf pixman cairo glib-2.0 jpeg"
DEPENDS += "wayland virtual/egl pango libinput"

Additionally to those dependencies, Weston requires the OpenGL ES and G2D libraries to do the final composition, Looks like you have no included they are already part of the default image.

Once your image has been properly generated, you will find the Weston source codes in:

<YOUR YOCTODIR>/build-wayland/tmp/work/cortexa9hf-vfp-neon-mx6qdl-linux-gnueabi/weston/1.9.0-r0/weston-1.9.0

Hope this helps

But， after system start up, launch weston manually in terminal, some logs can output  with compositor backend error , maybe just some configurations is wrong?:

root@(none):~/.config# export XDG_RUNTIME_DIR=/run/user/root/
root@(none):~/.config#
root@(none):~/.config#
root@(none):~/.config# weston
