在 beaglebone black上的Linux系统 开机启动自己的QT程序
把自己编译好的mycomtest程序放在/usr/bin/qtopia/myproject
看/etc/init.d下有没有rc.local，没有的话，创建一个，有的话，就在里面直接的exit 0前添加 /usr/bin/qtopia/myproject /mycomtest -qws & ,开机就能启动。
我的机子里没有rc.local文件，则有以下步骤：
#touch /etc/init.d/rc.local
#chmod +x /etc/init.d/rc.local
#vi /etc/init.d/rc.local
#ln -sf /etc/init.d/rc.local /etc/rc0.d/K999rc.local
#ln -sf /etc/init.d/rc.local /etc/rc1.d/K999rc.local
#ln -sf /etc/init.d/rc.local /etc/rc2.d/S999rc.local
#ln -sf /etc/init.d/rc.local /etc/rc3.d/S999rc.local
#ln -sf /etc/init.d/rc.local /etc/rc4.d/S999rc.local
#ln -sf /etc/init.d/rc.local /etc/rc5.d/S999rc.local
#ln -sf /etc/init.d/rc.local /etc/rc6.d/K999rc.local
/etc/init.d/rc.local的内容为：
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
/usr/bin/qtopia/myproject /mycomtest -qws &
exit 0
结果：开机自启动成功。
