Q1：

backend/event.cpp: In static member function ‘static int Event::dayOfWeek(char)’:

backend/event.cpp:419: error: ISO C++ says that these are ambiguous, even though the worst conversion for the first is better than the worst conversion for the second:

backend/event.cpp:419: note: candidate 1: operator<=(int, int) <built-in>

/home/henryfok/TrollTech/qt-2.3.10/include/qstring.h:312: note: candidate 2: int operator<=(char, QChar)

make[4]: *** [.obj/release-shared/event.o] Error 1

make[4]: Leaving directory `/home/henryfok/TrollTech/qtopia-free-2.1.1/src/libraries/qtopia'

make[3]: *** [all] Error 2

make[3]: Leaving directory `/home/henryfok/TrollTech/qtopia-free-2.1.1/src/libraries/qtopia'

make[2]: *** [sub-libraries-qtopia] Error 2

make[1]: *** [all] Error 2

make[1]: Leaving directory `/home/henryfok/TrollTech/qtopia-free-2.1.1/src'

make: *** [all] Error

解决办法：

修改 qtopia-free-2.1.1/src/libraries/qtopia/backend/event.cpp 文件的第419行

将while ( !( i & day ) && i <= Event::SUN ) 行改为

while ( !static_cast<int>(( i & day ) && i) <= Event::SUN )

哦，我编译的时候没有碰到过这个。呵呵。
