From FEDORA_PATCHES Mon Sep 17 00:00:00 2001 From: Kevin Buettner Date: Thu, 18 Feb 2021 23:04:29 -0700 Subject: gdb-rhbz1930528-fix-gnulib-build-error.patch ;; Backport fix for rawhide build error (RH BZ 1930528). amd64-linux-siginfo.c: Adjust include order to avoid gnulib error On Fedora rawhide, after updating to glibc-2.33, I'm seeing the following build failure: CXX nat/amd64-linux-siginfo.o In file included from /usr/include/bits/sigstksz.h:24, from /usr/include/signal.h:315, from ../gnulib/import/signal.h:52, from /ironwood1/sourceware-git/rawhide-gnulib/bld/../../worktree-gnulib/gdbserver/../gdb/nat/amd64-linux-siginfo.c:20: ../gnulib/import/unistd.h:663:3: error: #error "Please include config.h first." 663 | #error "Please include config.h first." | ^~~~~ glibc-2.33 has changed signal.h to now include which, in turn, includes . For a gdb build, this causes the gnulib version of unistd.h to be pulled in first. The build failure shown above happens because gnulib's config.h has not been included before the include of . The fix is simple - we just rearrange the order of the header file includes to make sure that gdbsupport/commondefs.h is included before attempting to include signal.h. Note that gdbsupport/commondefs.h includes . Build and regression tested on Fedora 33. On Fedora rawhide, GDB builds again. gdb/ChangeLog: * nat/amd64-linux-siginfo.c: Include "gdbsupport/common-defs.h" (which in turn includes ) before include of . diff --git a/gdb/nat/amd64-linux-siginfo.c b/gdb/nat/amd64-linux-siginfo.c --- a/gdb/nat/amd64-linux-siginfo.c +++ b/gdb/nat/amd64-linux-siginfo.c @@ -17,8 +17,8 @@ You should have received a copy of the GNU General Public License along with this program.
