From ac31906909ef7db7e111920f340cc6edd812e8e0 Mon Sep 17 00:00:00 2001 From: Philippe Proulx Date: Sat, 29 Oct 2016 13:32:57 -0400 Subject: [PATCH] Fix: lttng-ust-elf.c: define NT_GNU_BUILD_ID if not defined On uClibc, NT_GNU_BUILD_ID is not defined, so we define it manually in this case. This definition is the number given to the .note.gnu.build-id section (of type SHT_NOTE) of a linked ELF object. The ELF note headers give name "GNU" and type 3 (NT_GNU_BUILD_ID) for a build ID note, of which there can be only one in a linked object [...] See http://fedoraproject.org/wiki/RolandMcGrath/BuildID Signed-off-by: Philippe Proulx Signed-off-by: Mathieu Desnoyers --- liblttng-ust/lttng-ust-elf.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/liblttng-ust/lttng-ust-elf.c b/liblttng-ust/lttng-ust-elf.c index 5f27920e..beaa7f3b 100644 --- a/liblttng-ust/lttng-ust-elf.c +++ b/liblttng-ust/lttng-ust-elf.c @@ -29,6 +29,10 @@ #define BUF_LEN 4096 +#ifndef NT_GNU_BUILD_ID +# define NT_GNU_BUILD_ID 3 +#endif + /* * Retrieve the nth (where n is the `index` argument) phdr (program * header) from the given elf instance. -- 2.34.1
