Why nothing change after I modified some codes in C++ block and successfully compiled it?

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.
