Hi fellow Debian hams and Gnuradio experts,
I am currently trying to build a SDR experimental application based on Gnuradio for digital voice and data communications in the amateur radio VHF-UHF bands [1][2]. I am using Gnuradio 3.7.10 on Debian GNU/Linux from jessie-backports. I ran into some problems which I will describe below and which may be solved with your kind help.
1. Trying to build gnuradio-qtgui support in, I encountered these errors:
g++ -c -pipe -O2 -D_REENTRANT -Wall -W -DQT_WEBKIT -DQT_NO_DEBUG -DQT_SQL_LIB -DQT_GUI_LIB -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I../../qradiolink_mobile -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtNetwork -I/usr/include/qt4/QtGui -I/usr/include/qt4/QtSql -I/usr/include/qt4 -I. -I. -I../../qradiolink_mobile -I. -o dtmfcommand.o ../dtmfcommand.cpp

It seems as if the relevant header from gnuradio references the wrong path of QWT. I can make it build by editing the headers to provide the QWT directory:
