Title: A13 Olinuxino debian QT4.8.5
Post by: mimi1962 on May 12, 2014, 12:20:30 AM
hello

i was compiled qt with the method of nick guthrie with this ./configure (i use the video vga with gnome-core)

./configure -v -opensource -confirm-license -prefix /usr/local/qt485 -embedded arm -xplatform qws/linux-arm-g++ -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 -fast -little-endian -host-big-endian -no-pch -no-sql-ibase -no-sql-odbc -no-sql-psql -no-webkit -no-qt3support -nomake examples -nomake demos -nomake docs -nomake translations -qt-mouse-tslib

the compile and the link are ok

but with i launch the application ./gpio i find this error

./gpio: symbol lookup error: ./gpio: undefined symbol: _ZN7QWidget8qwsEventEP8QWSEvent

best regards and thank you for your response
