Hi,

I have followed the installation instructions on ubuntu 18.04 64-bit using R 3.6, all the dependencies have been installed but I am still getting this error:

Error: package or namespace load failed for ‘mqtt’ in dyn.load(file, DLLpath = DLLpath, ...): unable to load shared object '/home/niaz/R/x86_64-pc-linux-gnu-library/3.6/00LOCK-mqtt/00new/mqtt/libs/mqtt.so': /home/niaz/R/x86_64-pc-linux-gnu-library/3.6/00LOCK-mqtt/00new/mqtt/libs/mqtt.so: undefined symbol: _ZTIN6mosqpp11mosquittoppE

Any idea why I am getting this error. cheers
