Beginning with version 3.18.7, `hpcups` fails with > DEBUG: imageProcessorStartPage failed and segfaults (tested with HP LaserJet 1000 printer). Upstream bug reports: * https://bugs.launchpad.net/hplip/+bug/1788706 * https://bugs.launchpad.net/hplip/+bug/1787289 There is a patch available in one of the reports: https://bugs.launchpad.net/hplip/+bug/1787289/+attachment/5176026/+files/hplip.patch It applies to 3.18.7, but not to later versions. This commit adds a slight adaption of the patch that applies to versions 3.18.9 -- 3.19.6. The patch fixes https://github.com/NixOS/nixpkgs/issues/58949 . Note that the patch is merely a workaround: It simply removes all calls into the ImageProcessor library from `HPCupsFilter.cpp`.
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels https://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-19.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-19.03
For pull requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
