Dear Activecat,

I run the whole GNURadio C++ codes in Qtcreator without any problem by  
adding these lines to its .pro file:

LIBS += /usr/lib/libboost\_signals.so\

/usr/lib/libboost\_signals.so.1.48.0\

/usr/lib/libboost\_system-mt.so\

/usr/lib/libboost\_system.so\

/usr/lib/libboost\_system.so.1.48.0\

/usr/lib/libboost\_thread-mt.so\

/usr/lib/libboost\_thread.so\

/usr/lib/libboost\_thread.so.1.48.0\

/usr/lib/libboost\_timer-mt.so\

/usr/lib/libboost\_timer.so\

-L/usr/local/lib -lgnuradio-audio -lgnuradio-runtime -lgnuradio-pmt  
-lgnuradio-blocks -lgnuradio-filter

LIBS+= -L/usr/local/lib -lgnuradio-analog -lgnuradio-runtime  
-lgnuradio-pmt -lgnuradio-audio -lgnuradio-blocks -lgnuradio-filter

LIBS+=-lboost\_system -lboost\_thread-mt -lboost\_thread  
-lboost\_filesystem-mt -lboost\_filesystem -lgnuradio-qtgui  
-lgnuradio-fft

LIBS += -lfftw3f -lfftw3 \

I didn’t reveal the big picture because I thought I doesn’t help to  
figure out the problem 🙂

I finally found the problem! That was so hard to me to do so! I  
suddenly recognized that the proceeding block which is connected to  
input ports of this block , have a problem and that is, I set the item  
sizes of the previous blocks output as gr\_complex but in its work  
function I set the pointer to the ouput\_items as “byte” instead of  
gr\_complex!!!

Anyway, I have to thank all of you following my questions sincerely.

Best,

Mostafa
