Hi Marcus, Thanks so much for the advice, I really appreciate it! So when I tried that, it did work, and I was able to run a flowgraph successfully in GNU Radio 3.7, so that's good.
In the process of attempting to install some more packages (specifically gr-ata), I found that I needed to upgrade to GNU Radio version 3.8 or 3.9. So I followed these instructions: https://wiki.gnuradio.org/index.php/InstallingGR#Ubuntu_PPA_Installation to install GNU Radio 3.9.0. Then, I deleted the gr-sigmf directory I had cloned and built from, then attempted to re-install gr-sigmf (again using these instructions: https://github.com/skysafe/gr-sigmf). For some reason I now can get through running cmake, but things get stuck when I try to run make; here's the output: [ 2%] Building CXX object lib/CMakeFiles/gnuradio-sigmf.dir/sink_impl.cc.o /home/ewhite/src/gr-sigmf/lib/sink_impl.cc: In static member function ‘static gr::sigmf::sink::sptr gr::sigmf::sink::make(std::__cxx11::string, std::__cxx11::string, gr::sigmf::sigmf_time_mode, bool)’: /home/ewhite/src/gr-sigmf/lib/sink_impl.cc:81:40: error: could not convert ‘gnuradio::get_initial_sptr(T*) [with T = gr::sigmf::sink_impl]()’ from ‘std::shared_ptr<gr::sigmf::sink_impl>’ to ‘gr::sigmf::sink::sptr {aka boost::shared_ptr<gr::sigmf::sink>}’ return gnuradio::get_initial_sptr(new sink_impl(type, filename, time_mode, append)); ~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from /usr/include/gnuradio/basic_block.h:16:0, from /usr/include/gnuradio/block.h:15, from /usr/include/gnuradio/sync_block.h:15, from /home/ewhite/src/gr-sigmf/include/sigmf/sink.h:24, from /home/ewhite/src/gr-sigmf/lib/sink_impl.h:33, from /home/ewhite/src/gr-sigmf/lib/sink_impl.cc:45: /home/ewhite/src/gr-sigmf/lib/sink_impl.cc: In member function ‘void gr::sigmf::sink_impl::on_command_message(pmt::pmt_t)’: /home/ewhite/src/gr-sigmf/lib/sink_impl.cc:306:55: error: invalid operands of types ‘const char [22]’ and ‘uint64_t {aka long unsigned int}’ to binary ‘operator<<’ GR_LOG_INFO(d_logger, "setting capture meta(" << index_int << "," << key << ", " << val << ")"); ~~~~~~~~~~~~~~~~~~~~~~~~^~~~ lib/CMakeFiles/gnuradio-sigmf.dir/build.make:110: recipe for target 'lib/CMakeFiles/gnuradio-sigmf.dir/sink_impl.cc.o' failed make[2]: *** [lib/CMakeFiles/gnuradio-sigmf.dir/sink_impl.cc.o] Error 1 CMakeFiles/Makefile2:174: recipe for target 'lib/CMakeFiles/gnuradio-sigmf.dir/all' failed make[1]: *** [lib/CMakeFiles/gnuradio-sigmf.dir/all] Error 2 Makefile:140: recipe for target 'all' failed make: *** [all] Error 2 Do you have any idea what might be going on here, or what I should do next? Thanks Marcus! Have a good morning. Cheers, Ellie On Thu, Jun 18, 2020 at 10:46 AM Marcus D.
