From 06e4fe64bbd01f16ee84da161b8e1a61e73b4cdb Mon Sep 17 00:00:00 2001 From: Alexey Neyman Date: Thu, 31 Mar 2016 13:02:47 -0700 Subject: [PATCH] Provide an alias to _obstack_free GDB 7.11 does not build if compiled against uclibc-ng (1.0.12 was used, but the problematic code exists in 1.0.13 as well). The reason is that GDB release includes its own obstack implementation, but elides the code if declares a compatible obstack implementation in libc. uclibc-ng does claim compatible obstack interface (GDB expects version 2, but accepts version 1 if sizeof(int) == sizeof(size_t)), however, uclibc-ng does not provide the _obstack_free symbol that is a part of the interface (glibc does provide this symbol). This later causes a link failure. The attached patch makes uclibc-ng enables an alias _obstack_free -> obstack_free.
