Subject: [Buildroot] [PATCH v3 1/7] package/gcc: fix build issue with glibc 2.26
Date: Sat, 23 Sep 2017 23:24:00 +0200 [thread overview]
Message-ID: <20170923212414.16744-2-romain.naour@gmail.com> (raw)
In-Reply-To: <20170923212414.16744-1-romain.naour@gmail.com>
In file included from ../../../libgcc/unwind-dw2.c:403:0:
./md-unwind-support.h: In function ??aarch64_fallback_frame_state??:
./md-unwind-support.h:58:21: error: field ??uc?? has incomplete type
struct ucontext uc;
^~
The fix is already included in gcc 7.2 release [1]. We have to backport it to
all older gcc release since it's not included in any stable release yet.

+Subject: [PATCH] Use ucontext_t not struct ucontext in linux-unwind.h files.
+
+Current glibc no longer gives the ucontext_t type the tag struct
+ucontext, to conform with POSIX namespace rules. This requires
+various linux-unwind.h files in libgcc, that were previously using
+struct ucontext, to be fixed to use ucontext_t instead. This is
+similar to the removal of the struct siginfo tag from siginfo_t some
+years ago.
+
+This patch changes those files to use ucontext_t instead. As the
+standard name that should be unconditionally safe, so this is not
+restricted to architectures supported by glibc, or conditioned on the
+glibc version.
+
+Tested compilation together with current glibc with glibc's
+build-many-glibcs.py.
+

+This patch changes those files to use ucontext_t instead. As the
+standard name that should be unconditionally safe, so this is not
+restricted to architectures supported by glibc, or conditioned on the
+glibc version.
+
+Tested compilation together with current glibc with glibc's
+build-many-glibcs.py.
+
