一. 背景
从向日葵官网下载了linux版向日葵远程控制端软件，解压后直接执行Sunlloginremote发现以下错误:
jello@jello:~/sunlogin_remote_linux$ ./SunloginRemote
This application failed to start because it could not find or load the Qt platform plugin "xcb".
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, xcb.
Reinstalling the application may fix this problem.
Aborted (core dumped)
二. 解决方案
安装32bit的依赖库,命令如下:
sudo apt-get install libsm-dev:i386
三. 如何知道缺少sm依赖库呢？
3.1 先指定一个环境变量以便进入QT的调试模式,将会输出一些调试信息
exportQT_DEBUG_PLUGINS=1
3.2 启动程序后输出以下错误信息
QLibraryPrivate::loadPlugin failed on "/home/jello/sunlogin_remote_linux/plugins/platforms/libqxcb.so" : "Cannot load library /home/jello/sunlogin_remote_linux/plugins/platforms/libqxcb.so: (libSM.so.6: cannot open shared object file: No such file or directory)"
