20250408在荣品的PRO-RK3566开发板使用Rockchip原厂的buildroot系统时加入gnome-screenshot命令【直接编译进IMG】
2025/4/7 17:57
荣品的PRO-RK3566开发板，4GB+32GB内存。
缘起：请问在飞凌的OK3588-C_Linux5.10.209+Qt5.15.10_用户资料_R1如果使用 weston-screenshooter 截屏？
在Android12/13下都可以很方便的使用screencap截屏。
现在 在linux/Buildroot千辛万苦中找到了weston-screenshooter，失败/异常了。
请问该如何使用？语法错误？还是该如何配置呢？

修改步骤：
将/etc/init.d/S49weston中的：
/usr/bin/weston&
修改成为：
/usr/bin/weston --debug &
重启就可以使用weston-screenshooter了！

直接修改output目中的./buildroot/output/rockchip_rk3566/target/etc/init.d/S49weston
之后直接打包，是否可行，没有验证。

weston桌面系统截屏方法
二月 3, 2023
使用weston-screenshooter
但必须启用weston桌面--debug选项，否则会出现以下错误：
[root@RK356X:/]# weston-screenshooter
[02:41:05.145] libwayland: error in client communication (pid 776)
weston_screenshooter@5: error 0: screenshooter failed: permission denied. Debug protocol must be enabled
以RK3568开发板，buildroot系统为例，修改/etc/init.d/S50launcher，找到weston所在行，添加--debug选项。
......
# Uncomment to disable mirror mode
# unset WESTON_DRM_MIRROR
export XDG_RUNTIME_DIR=${XDG_RUNTIME_DIR:-/var/run}
export QT_QPA_PLATFORM=${QT_QPA_PLATFORM:-wayland}
weston --tty=2 --debug --idle-time=0&
{
# Wait for weston ready
while [ ! -e ${XDG_RUNTIME_DIR}/wayland-0 ]; do
sleep .1
done
/usr/bin/QLauncher &
}&
......
forlinx开发板使用的yocto系统也类似，修改/lib/systemd/system/weston.service，在weston后添加--debug选项。
$ vi /lib/systemd/system/weston.service
# 修改如下
# ExecStart=/usr/bin/weston --debug --log=${XDG_RUNTIME_DIR}/weston.log $OPTARGS
然后重启系统，之后就可以使用weston-screenshooter截取屏幕了。
