Subject: Re: [RFA]: Patch to handle new libunwind release
Date: Wed, 04 Aug 2004 18:17:00 -0000	[thread overview]
Message-ID: <4111283B.9000902@gnu.org> (raw)
In-Reply-To: <410FB16F.80107@redhat.com>

> The attached patch changes libunwind-frame.c to dlopen "libunwind-xxxx.so" instead of "libunwind.so".  This is needed as the design has changed in libunwind 0.97 and the interface functions are no longer found in the vanilla library.  Without the patch, ia64 debugging will revert to the examine prologue method which cannot handle a number of scenarios, including backtraces on threads.

I feel ill

+#ifndef LIBUNWIND_SO
+#define LIBUNWIND_SO "libunwind-" STRINGIFY(UNW_TARGET) ".so"
+#endif

however, we've clearly got no choice, so "obvious".
