[Qt-interest] Why all my program run with error which compiled by qtopia-phone-4.2.1?

[Kermit Mei]

Hello, I compiled qtopia-phone-4.2.1 on ubuntu9.04 with gcc/g++4.1.3.
I compile my program like this:

$ qtopiamake -project
Created Calendar.pro
$ qtopiamake
Cleaning out stale build files...
Finding project files...
  1 projects found.
$ make
... (everything goes well) ...

Then I setup qvfb:
kermit at kermit-desktop:~$ qvfb 
Using display 0

After that, I run my program with the argument '-qws' like this:
/****** show files ******/
$ ls
Calendar      Calendar.pro        dayview.h  Makefile.target
calendar.cpp  Calendar.pro.cache  main.cpp   monthview.cpp
calendar.h    dayview.cpp         Makefile   monthview.h

/****** Errors ******/
$ ./Calendar -qws

All of the executable program compiled with qtopia run with this error,
included the qtopia's example. I don't know what's wrong.

Can anyone help me,plseas?


Thank you.
