From a1b5ec256a03e12d667837fca8bf42f20675916f Mon Sep 17 00:00:00 2001 From: jsg Date: Fri, 1 Feb 2019 05:27:37 +0000 Subject: add libelf from elftoolchain r3669 A 2 clause BSD licensed implementation of the SVR4 ELF API also implemented by mr511.de libelf (devel/libelf in ports) and elfutils. It is being added to base to allow Mesa to use it in future. shlib major is higher than devel/libelf and pkg-config version is 0.8.2 to pass a glib2 configure test so this can replace the use of devel/libelf in ports. --- lib/libelf/elf_version.c | 50 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 50 insertions(+) create mode 100644 lib/libelf/elf_version.c (limited to 'lib/libelf/elf_version.c') diff --git a/lib/libelf/elf_version.c b/lib/libelf/elf_version.c new file mode 100644 index 00000000000..f9cdabd6c8b --- /dev/null +++ b/lib/libelf/elf_version.c @@ -0,0 +1,50 @@ +/*- + * Copyright (c) 2006,2008 Joseph Koshy + * 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.
