6 个解决方案
#1
"lily.h:13:22: qvariant.h: 没有那个文件或目录"
应该是缺少头文件。
应该是缺少头文件。
#2
在lily.h中include了qvariant.h， qwidget.h等几个文件，但是编译系统没有找到该文件。编译系统将在如下几个目录查找所需include的文件：
1） 执行make命令的当前目录
2） g++中-I选项后所指定的目录
3） 系统目录，既PATH环境变量设置的目录
你应该找到qvariant.h， qwidget.h所在目录，使用-I选项将其加入到搜索目录中。

2） g++中-I选项后所指定的目录
3） 系统目录，既PATH环境变量设置的目录

把 -i 选项加上，后面跟上你要包含的头文件
#4
我按大侠的意思把对应的头文件加进来，还是提示同样的错误啊

自动生成的，肯定已经加了！
再检查一下你的makefile！
估计是你的libs搞错了

qwidget.h 应该是 QT3 和以前版本的头文件
如果用 QT4 编译 QT3 代码需要定义
