I've never built xine myself, as I don't use it. It must have come as a dependency for kde or something but I'm 100% sure I've never ran nix-build or nix-env for it directly. > > If you get some output we'll know more, if you don't we'll have to > continue digging for the cause. Well it's not that big an issue. I think in this case it's pretty safe to manually delete it, but it would be nice to find out what happened. > > Marc Weber > _______________________________________________ > nix-dev mailing list > nix-dev@lists.science.uu.nl > http://lists.science.uu.nl/mailman/listinfo/nix-dev _______________________________________________ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
