Mikael Pettersson <mikpelinux at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mikpelinux at gmail dot com --- Comment #1 from Mikael Pettersson <mikpelinux at gmail dot com> --- Ada only supports being built by the same or older releases, while you're trying to bootstrap gcc-10.5 using gcc-13.1. That won't work in general. (For Canadian crosses it must be the exact same version.)
