[Discuss-gnuradio] Why nothing change after I modified some codes in C++ block and successfully compiled it?

2013-03-05 Thread Yingjie Chen 
Hi guys,

Thanks in advance.

I have added some codes in c++ block, like *printf(i=%d\n,z);* for output
test. However, after I compiled the modified block *(.cc file)*and
generated the new  object file* (.cc.o file)*, nothing printed out from the
terminal, which means nothing changed in the original code. But actually I
did.  I feel so confused, hope everyone can help me.

The example I used is in */home/k/src/gnuradio/gr-digital/examples/ofdm*,
and the file I modified is
/home/k/src/gnuradio/build/gnuradio-core/src/lib/gengen/*
gr_peak_detector_fb.cc*, which is one c++ block connected by ofdm example.

Best,
Kay.

You have to run 'make install' after rebuilding or the system will
just use the old installed libraries.
