Thanks for the replies guys. Tom, I have modified this flowgraph
(extensively) from one of the examples and have been using its
CMakeLists.txt file (modifying it along the way of course). The commands
that I use to build it are
mkdir build
cd build
cmake ../
make
I believe that -l gnuradio-qtgui would be for g++. Since I am not using
g++ directly I tried adding the following to my CMakeLists.txt file.
# libgnuradio-qtgui.so
#find_package(gnuradio-qtgui)
include_directories(/usr/local/lib)
When the find_package command did not work, I commented it out and
included the directory absolutely. I have had to do this a lot lately.
Some of the library variables seem to have not gotten set by the build
script (granted, this build is from the summer). Unfortunately I am
still getting the
undefined reference to `qtgui_make_sink_c(int, int, double, double,
std::basic_string<char, std::char_traits<char>, std::allocator<char> >
const&, bool, bool, bool, bool, QWidget*)'
error. My syntax is
qtgui_sink_c_sptr qtsink = qtgui_make_sink_c (fftsize,
gr_firdes::WIN_HAMMING, 0, 1.0, "Spectrum Display", true, true, true,
true, NULL);
I am including the following relevant components
#include <qtgui_sink_c.h>
#include <QApplication>
#include <QWidget>
Can anyone spot my mistake?
-Dan
