configure: error: Couldn't find required function socket

[baptx]

Hello, when trying to build, I get the error configure: error: Couldn't find required function socket. Do you have a solution to fix this issue? I tested on Ubuntu 20.04 LTS and Debian 10.

I did not find complete build instructions (like someone mentioned at https://github.com/mawis/jabberd/issues/11), the README has install instructions saying we first need to run the configure script but there is not configure script by default and it also says:

If you need support for your jabberd14, please go to http://jabberd.org/gettingSupport

Which returns a "404 Not Found" error page. So I used generic build instructions found at https://stackoverflow.com/questions/2531827/what-are-makefile-am-and-makefile-in/30511996#30511996:

autoreconf --install
mkdir build
cd build
../configure

I am trying to build the server myself because it looks like there is no Ubuntu or Debian package.
