Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the simply-static domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.

树莓派开机启动GUI程序

树莓派开机启动GUI程序

1、如果是lite版,先安装界面,https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=133691

参考上面界面,多种界面添加方法及比较。

2、将我们的程序拷贝到树莓派,依赖库之类的也添加好。

3、要想启动自己的图形界面,就需要启动X server,这个东西是在你登录树莓派输入用户名和密码之前启动的,所以我们可以在启动树莓派之前和启动X server之后启动自己的程序,/etc/profile 这个文件就是这两个程序的中间,我们直接更改这个配置文件就行了

sudo nano /etc/profile
在文件开头输入你程序的路径prg,再执行你的程序guiprogram,如下:

cd /home/pi/prg
./guiprogram

另一种方法是增加环境变量,程序guiprogram在/home/pi/Downloads/dist/下,直接执行即可

# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).
if [ "`id -u`" -eq 0 ]; then
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games:/home/pi/.local/bin:/home/pi/Downloads/dist"
fi
export PATH
guiprogram
