From fb51d98562a26b6dcde7d3597938a0b707b6b881 Mon Sep 17 00:00:00 2001 From: Bill Hoffman Date: Fri, 30 Oct 2009 13:10:56 -0400 Subject: Switch to using libarchive from libtar for cpack and cmake -E tar This allows for a built in bzip and zip capability, so external tools will not be needed for these packagers. The cmake -E tar xf should be able to handle all compression types now as well. --- .../libarchive/archive_write_set_format_mtree.c | 1050 ++++++++++++++++++++ 1 file changed, 1050 insertions(+) create mode 100644 Utilities/cmlibarchive/libarchive/archive_write_set_format_mtree.c (limited to 'Utilities/cmlibarchive/libarchive/archive_write_set_format_mtree.c') diff --git a/Utilities/cmlibarchive/libarchive/archive_write_set_format_mtree.c b/Utilities/cmlibarchive/libarchive/archive_write_set_format_mtree.c new file mode 100644 index 0000000000..68dc92b563 --- /dev/null +++ b/Utilities/cmlibarchive/libarchive/archive_write_set_format_mtree.c @@ -0,0 +1,1050 @@ +/*- + * Copyright (c) 2009 Michihiro NAKAJIMA + * Copyright (c) 2008 Joerg Sonnenberger + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
