Hello,

Now I have installed Linux in my laptop and I have tried to install gr-lora package, but I am still getting this error:

komro@komro-HP-ProBook-6560b:~/gnuradio/gr-lora/build$ make && sudo make install
make[2]: *** No rule to make target '/usr/lib/x86_64-linux-gnu/liborc-0.4.so', needed by 'lib/libgnuradio-lora.so.v0.6.2-54-g6111c350'.  Stop.
make[1]: *** [CMakeFiles/Makefile2:248: lib/CMakeFiles/gnuradio-lora.dir/all] Error 2
make: *** [Makefile:141: all] Error 2
komro@komro-HP-ProBook-6560b:~/gnuradio/gr-l

I have installed all the necessary dependencies too, but don't know what is wrong here!

Any hint would be much appreciated!

The solution is: sudo apt-get install liborc-0.4-dev

Apart from setting correct pythonpath, It is also important to use the 'DCMAKE...' argument to make sure everything installs in right path!

While installing 'gr-lora' module please use the command

komro@komro-HP-ProBook-6560b:~/gnuradio/gr-lora/build$ cmake -DCMAKE_INSTALL_PREFIX=/usr ../

instead of

komro@komro-HP-ProBook-6560b:~/gnuradio/gr-lora/build$ cmake ../

This solved my issue!
