Hello,
After a bit of a struggle, I finally managed to compile the dial_tone.cc
example included with gnuradio. The issue I was having was that when
running cmake and then make, make would return "fatal error:
gr_top_block.h: No such file or directory". I found the header it was
referring to in /usr/local/include/gnuradio/ and managed to get around the
error by adding "include_directories(/usr/local/include/gnuradio)" to
CMakeLists.txt. This works but it seems like there has to be a better way?
Is there a PATH that I can add this to or something of that sort? CPPFLAGS
seemed promising but adding "export
CPPFLAGS=$CPPFLAGS:/usr/local/include/gnuradio/" to my bashrc does not seem
to do anything. Also, I plan on writing some C++ flowgraphs in the near
future and was wondering how to determine which directories to include in
the CMakeLists.txt file? The dial tone example has ${GR_AUDIO_INCLUDE_DIRS}
and ${GNURADIO_CORE_INCLUDE_DIRS}. Is there a list of such variables that
correspond to certain header files, etc.? Thanks ahead of time!-Dan
