[SOLVED] ftbfs: error: ‘enet_address_get_host_ip’ was not declared in this scope

[GunChleoc]

Are there any new dependencies that haven't been documented on the wiki yet?

I have Ubuntu 20.04-based Linux Mint. SVN r24660.

I cleaned the workspaces and rebuilt without any parameters.

Do you use with system enet ?

 

What's your gcc version

[GunChleoc]

gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

> Do you use with system enet ?

I have no idea how to do that and there is no such switch documented on https://trac.wildfiregames.com/wiki/BuildInstructions, so I guess the answer is "no". My system has libenet-dev version 1.3.13+ds-1 (= libenet7)

[Stan`]

Okay, so that rules out my two first hypothesis.

Make sure you don't have some extra unversioned files lying around. Sometimes files stay in the repo.

[s0600204]

@GunChleoc, you appear to have an old version of enet installed in /usr/local/include/enet, which is being used instead of the Ubuntu-repository-provided version.

[GunChleoc]

Yep, that's it. I deleted it and now the build system is picking the system-provided one in usr/include/enet.

[GunChleoc]

I have now found out where my 2 enet versions are coming from: I am also translating the Enigma game, which uses an older version of enet.

I don't know how the 0AD build system works; @wraitii would it be possible/worth the effort to look for the system enet before the usr/local enet, or to specify a minimum version and skip the usr/local match?
