Configure failure with qt-mobility-opensource-src-1.0.0 on QT4.6.2 on Ubuntu9.04

[borton]

Dear sirs,
After I set up QT4.6.2 on Ubuntu, I downloaded qt-mobility-opensource-src-1.0.0 and followed the instructions in doc/installation.html, I encountered a failure after running ./configure . The error messages are extracted as follows:
..............
Package conninet was not found in the pkg-config search path.
Perhaps you should add the directory containing `conninet.pc'
to the PKG_CONFIG_PATH environment variable
No package 'conninet' found
QMAKESPEC has not been set, so configuration cannot be deduced.
Error processing project file: /android_src/EB306/QT/qt-mobility-opensource-src-1.0.0/qtmobility.pro

I surveyed the suggestions from internet:
export QMAKESPEC =/opt/qtsdk-2010.02/qt/mkspecs
or export QMAKESPEC =/opt/qtsdk-2010.02/qt/mkspecs/arm-linux
But still in vain with same error message.

I've also tried another codebase qt-mobility-src-1.0.0-tp2, but it went to the same result.

Could someone help provide your suggestions or opinions?

If this is not a proper place for this question, please kindly let me know as well.

Thanks a lot!

Here comes the update for this issue.
I found that it's due to my mis-using the cross compiler. I should use the g++ instead of arm-linux-g++. Then "./configure" works well! :)

However, while perfoming "make" , there are so many compiling errors.Ex:

I'm wondering if it's related to C++/4.3?

If anyone has any idea, please kindly let me know.
Thanks a lot!
