Install Qt for embedded ARM

[matteo.ceruti]

I compiled qt 4.7.4 for embedded arm without tslib include.
Now I must to compile and install with tslib for the touchescreen.
I follow the steps like the first time, then I exec

./configure -opensource -confirm-license -prefix /opt/qt -embedded arm -platform \qws/linux-x86-g++ -xplatform qws/linux-am35-g++ -depths 16,24,32 -no-mmx -no-3dnow -no-sse -no-sse2 -no-glib -no-cups -no-largefile -no-accessibility -no-openssl -no-gtkstyle -qt-mouse-pc -qt-mouse-linuxtp -qt-mouse-linuxinput -plugin-mouse-linuxtp -plugin-mouse-pc -qt-mouse-tslib -little-endian -host-little-endian -fast

but with the instruction
make clean
it is shown the following error:
Could not find mkspecs for your QMAKESPEC(mkspecs/qws/linux-am35-g++) after trying:
/usr/local/Trolltech/QtEmbedded-4.7.4-arm/mkspecs
Error processing project file: /home/l/qt-everywhere-opensource-src-4.7.4/src/plugins/sqldrivers/sqlite/sqlite.pro
make[3]: *** [Makefile] Error 3

Suggestions?
Thanks

Have you tried make confclean instead? What has changed in the configure from your previous successful build?
