Well, I mean, which kind of low-level API (maybe framebuffer driver) is
QtE based on.

Thanks, so I get "console" image and then cp below items to
"/opt/Trolltech/Qtopia" (FR), and finally launch qpe.sh in FR. Is it
right?

/opt/QtopiaSDK/build/qt-extended-4.4.2/image$ ls
bin  help  lib   plugins  qpe.sh            qt_plugins  sounds
etc  i18n  pics  qpe.env  qtopia_db.sqlite  services    weblets

I try to "Compiling an Example Qt Extended App" and found following
notes. See my environment variables, did I miss something?

daniel at daniel-laptop:/opt/Qtopia/build/myapps/example$
$QTOPIA_DEPOT_PATH
-bash: /opt/QtopiaSDK/qt-extended-4.4.2: is a directory
daniel at daniel-laptop:/opt/Qtopia/build/myapps/example$ $QPEDIR
-bash: /opt/QtopiaSDK/build/qt-extended-4.4.2: is a directory
daniel at daniel-laptop:/opt/Qtopia/build/myapps/example$ ls
examplebase.ui  example.desktop  help        main.cpp  qbuild.pro

You must run configure before you can run qtopiamake

Hmm... I seems that I can't be used for application based on OpenGL.
Maybe I have to Google again. Thanks :)
