I installed pre-cog following the last section of
https://github.com/buoyboy/pre-cog/wiki/Installation only. I already had working GNUradio with grextras installed, which I did by simply running the installation script
http://www.sbrac.org/files/build-gnuradio . Now strangely I see that many blocks from GRC are missing, though new blocks from pre-cog are there. I don't see blocks such as throttle. Can anyone suggest how to fix this? I am not super expert on linux, by the way, just learning as required.
Installation dirs: ~/Downloads/gnuradio, ~/Downloads/grextras, ~/Downloads/pre-cog and other folders similarly such as 'uhd', 'gr-baz' etc.
Thanks.
