How can I import ares.h file on mosquitto protocol?

Question

I've implemented mosquitto on my ARM target board.

I added -DWITH_SRV in Makefile, because I need to add SRV Loopup function on my system.

But it returns error

fatal error: ares.h: No such file or directory

I have no idea how can I fix it.

1. Just add ares.h file in /include folder? If then, loop up feature will be work normally?

2. Should install ares library on my system?

Could anyone answer about my question?

Answer 1

You need to have the c-ares library installed in your system. It should be pretty straightforward to install the libc-ares-dev package using your Linux distro package manager.

Alternatively, and for other operating sytems, you can get the library from its official website.
