报错：GDBusSignalInfo **signals error: expected unqualified-id before 'public'.原因:signals为QT关键字. 但是在glib2里把signals当做变量来使用，两者需要做兼容处理.解决方案：1.在xxx.pro文件加入CONFIG += no_keywords2.将项目文件使用public signalspublic slotsemit 这三个关键字的地方统统改为QT的宏:Q_SIGNALS (or Q.

C语言自身并没有提供IO，内存管理，字符串操作等类似的机制。作为弥补，C语言有一个标准库帮助C语言实现这些机制。我们在编译C程序的时候基本上都需要链接到这些库文件。 GNU C Library定义ISO C标准还有其他一些标准（POSIX）规定的函数库。...
