Ahoj,

I am trying to build this (latest git checkout (commit 2b5787e)) on Artix GNU/Linux (rolling release), according to this recipe.

GCC version: 14.2.1

Build fails with fe_util.hpp:283:19: error: ‘sf’ was not declared in this scope:

Same for me, in Garuda Linux, Arch based

gcc versión 14.2.1 20250207 (GCC)

Tried with release attract-2.6.2, and attract-2.7.0

Do you possibly have SFML-3 version? My compilation started fail after SFML upgrade from 2.6 to 3.0. I reverted back tp 2.6 and it compiles fine on Linux both with clang and gcc (14.3.0).

Do you possibly have SFML-3 version?

Of course. My distribution is rolling release, so almost up to date version of software.

If you require SFML 3.0.0 compatibility you might consider switching to Attract-Mode Plus
