[mosquitto-dev] Undefined reference to mosquitto_subscribe@@VERS_0.9

[alessio troiano <alessio@xxxxxxxx>]

Hi all,

I'm trying to compile my c++ mqtt client using libmosquitto, but the compiler say me this error:

Undefined reference to mosquitto_subscribe@@VERS_0.9

If I comment the function, the problem is on another function, for example:

Undefined reference to mosquitto_new@@VERS_0.9

What's the meaning of the message and how I can solve this problem?

Thank you in advance
