It should behave better now, but this is something I want to focus in next turn (branch) please, report any critical issues Top Quote

Aborting... This is using the AUR package for widelands-bzr on Archlinux which I always use. Did something change between 8401 and 8410? Top Quote

Please try to remove (rename) the build directory. The build directory is part of the directory 'src' (so src/build) in the directory where you run the makepkg command. After renaming try to run makepkg again. If this doesn't fix your issue, you may have to delete the directory 'widelands-bzr' and run over the whole process of downloading the PGKBUILD to create a clean build environment. If you are using yaourt: Looks like using yaourt for managing packages from AUR does not work for widelands: See the comments in AUR widelands-bzr Fight simulator for Widelands: https://wide-fighter.netlify.app/ Top Quote

I always get the warning too, but only once. So, I don't think that the warning itself is the issue. /usr/bin/ld: CMakeFiles/test_scripting.dir/scripting_test_main.cc.o: relocation R_X86_64_32 against.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC This looks like it might be an issue with the boild environment https://stackoverflow.com/questions/19364969/compilation-fails-with-relocation-r-x86-64-32-against-rodata-str1-8-can-not?rq=1 Busy indexing nil values Top Quote

They should be located in new folder: ai, in data dir, alongside with tribes, world, sound folders. Maybe problem with makefile Also line "There's no configuration file, using default values." is bit unclear/misleading. I will have to remove it, but this is not reason of the crash of course...

I have no such problems. SoundHandler: songset "ingame" does not exist! Never seen this. Fight simulator for Widelands: https://wide-fighter.netlify.app/ Top Quote
