Hmm, strange. I can't reproduce this issue on Arch Linux and never experienced it either. It seems you get this message while building the game using the provided makefile (by OpenRA devs).

This means the compilation process itself fails. Not sure if this has anything to do with the script. The message indicates this may be an issue of missing dependencies or conflicting packages...not sure, anyway. Have you checked your system and cleaned the /data/linux/arch_linux/ folder, excluding files openra-bleed-tibsunra2.install & PKGBUILD?

Btw. I've never got any messages related to Open.Nat installation.

My building process looks like this on Arch:

No, everything is clean.

Have you tried

• https://aur.archlinux.org/packages/openra-git/ (especially this one since it's practically the same openra version my script uses)

or

• https://www.archlinux.org/packages/community/any/openra/

if the compilation succeeds by using either of them? (as a reference, so we can narrow down your issue)
