From 37eb913ed8c4798b736e678f4dbd9f4a91a68f74 Mon Sep 17 00:00:00 2001 From: Salvatore Cro Date: Thu, 9 Sep 2010 15:45:44 +0200 Subject: libubacktrace: Provide uClibc with backtrace functions A new shared object, libubacktrace.so.0 is added to uClibc to provide backtrace functions to support application self-debugging. This set of functions requires to dynamically load libgcc_s.so so they need to call dlopen/dlsym that are provided by libdl. For this reason they cannot be included into libc.so.0 but are provided by a new library. User application that wants to use backtrace needs to be compiled with -fexceptions option and -rdynamic to get full symbols printed and must be linked against libubacktrace.so Signed-off-by: Carmelo Amoroso --- libubacktrace/sysdeps/sh/Makefile.arch | 12 ++++++++++++ 1 file changed, 12 insertions(+) create mode 100644 libubacktrace/sysdeps/sh/Makefile.arch (limited to 'libubacktrace/sysdeps/sh/Makefile.arch') diff --git a/libubacktrace/sysdeps/sh/Makefile.arch b/libubacktrace/sysdeps/sh/Makefile.arch new file mode 100644 index 000000000..9b0de385b --- /dev/null +++ b/libubacktrace/sysdeps/sh/Makefile.arch @@ -0,0 +1,12 @@ +# Makefile for uClibc (sh/libubacktrace) +# +# Copyright (C) 2010 STMicroelectronics Ltd +# Author: Carmelo Amoroso + +# Licensed under the LGPL v2.1, see the file COPYING.LIB in this tarball. +# + +libubacktrace_ARCH_SRC-y := backtrace.c + +# -fexections is required for backtrace to work using dwarf2 +CFLAGS-backtrace.c := -fexceptions -- cgit v1.2.3
