From 99b737ae9f3f1d35a4696594821fa3bc39e8aa87 Mon Sep 17 00:00:00 2001 From: Matthias Vogelgesang Date: Fri, 28 Sep 2012 18:16:56 +0200 Subject: Fix #146: Make a new top-level directory for cams ... and build a package for each camera. Moreover, for some reason we can live without the CMake generated spec file for RPM generation. AFAICS, the RPMs are prefixed correctly. --- src/cameras/uca-ufo-camera.c | 497 ------------------------------------------- 1 file changed, 497 deletions(-) delete mode 100644 src/cameras/uca-ufo-camera.c (limited to 'src/cameras/uca-ufo-camera.c') diff --git a/src/cameras/uca-ufo-camera.c b/src/cameras/uca-ufo-camera.c deleted file mode 100644 index 7542fdf..0000000 --- a/src/cameras/uca-ufo-camera.c +++ /dev/null @@ -1,497 +0,0 @@ -/* Copyright (C) 2011, 2012 Matthias Vogelgesang - (Karlsruhe Institute of Technology) - - This library is free software; you can redistribute it and/or modify it - under the terms of the GNU Lesser General Public License as published by the - Free Software Foundation; either version 2.1 of the License, or (at your - option) any later version. - - This library is distributed in the hope that it will be useful, but WITHOUT - ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS - FOR A PARTICULAR PURPOSE.
