[srslte-users] Device zmq not found while running srsue : Device zmq not found. Switching to auto mode

[Xavier Arteaga]

Hi Tushar,
Did you install zmq from sources?

First, one needs to install libzmq:
git clone https://github.com/zeromq/libzmq.git
cd libzmq
./autogen.sh
./configure
make
sudo make install
sudo ldconfig

Second, install czmq:
git clone https://github.com/zeromq/czmq.git
cd czmq
./autogen.sh
./configure
make
sudo make install
sudo ldconfig

Finally, you need to compile srsLTE (assuming you have already installed
all the required dependencies):
git clone https://github.com/srsLTE/srsLTE.git
cd srsLTE
mkdir build
cd build
cmake ../
make

Put extra attention in the cmake console output. Make sure you read the
following line:
...
-- FINDING ZEROMQ.
-- Checking for module 'ZeroMQ'
--   No package 'ZeroMQ' found
-- Found libZEROMQ: /usr/local/include, /usr/local/lib/libzmq.so
...
