QT5 compile error on ARM

[zhangshuang]

Hello everyone!
I want to build a QT5 embedded version. the compile method is the same as QT4.7.X,but I met a lot of errors,who can tell me the reason? Or,Is there any document about how to compile QT5 arm version?

complie tools:gcc version 4.4.1 (Sourcery G++ Lite 2009q3-67
compile command:

1. ./configure -opensource -arch arm -prefix /usr/local/qt5-arm -release -make libs -xplatform qws/linux-arm-g++ -force-pkg-config -no-xcb -I/usr/local/tslib/include - L/usr/local/tslib/lib
   2..make
