本文介绍了解决在ARM Linux环境下Qt应用程序因系统内核不支持Unix Domain Socket而导致的问题。主要内容包括如何编译Unix Domain Socket模块并将其加载到内核中，确保Qt应用程序能够正常运行。

$ modprobe unix # ./qt-app -qws need Unix Domain Socket module support

If you don't have unix module in your arm linux os, you need to compile unix module, which locates on linux-2.x.x/net/unix/ directory of linux-2.x.x source code tree. After make modules success, copy linux-2.x.x/net/unix/unix.ko to /lib/modules/linux-2.x.x/ kernel/net/unix/ directory of your arm linux os. Then $ modprobe unix.
