Hi Vasil,
1. How did you install gnuradio - from source or from the ppa repository? And how did you install gr-fcdproplus? > /usr/local/include/gnuradio/hier_block2.h:93:35: note: no known conversion for argument 1 from 'gr::fcdproplus::fcdproplus::sptr' {aka 'boost::shared_ptrgr::fcdproplus::fcdproplus'} to 'gr::basic_block_sptr' {aka 'std::shared_ptrgr::basic_block'} > 93 | void connect(basic_block_sptr src, int src_port, basic_block_sptr dst, int dst_port);
Since I needed a specific version of gnuradio, I built it from source and I didn't remember installing gr-fcdproplus seperately, it was all packaged together I guess! But anyhow it was found to be installed in my system.
2. One possible reason is two incompatible gnuradio versions installed on your system in different locations - `/usr/` and `/usr/local/`. Make sure to remove all other gnuradio versions and that there is no `/usr/include/gnuradio` directory. Then delete the build directory and start from scratch.
I removed the previous installations and built the new gnuradio from source (master branch) as you mentioned. But still the same error shows up. I also tried installing via sudo apt install gr-osmosdr, but still dind't get it in GRC Menu successfully!
3. Another possible reason is the version of gr-fcdproplus that you have installed is not compatible with your gnuradio version. > I just need the RTL-SDR component
You can try removing gr-fcdproplus as it is not needed for RTL-SDR devices. Seems like it is needed, when I remove it throws error earlier during any OOT module's make installation!
Is there any simple way where I can get both RTL-SDR and USRP blocks in GNUradio? Any advice would be much appreciated!
