From c49fbc6c79e0c479371e0ba7be0c8d1137016864 Mon Sep 17 00:00:00 2001 From: John Baldwin Date: Mon, 4 Sep 2017 19:34:48 -0700 Subject: [PATCH] Define _KMEMUSER before including BSD kernel headers. Recent versions of NetBSD hide certain kernel structures needed by the KVM target from userland unless this macro is defined. gdb/ChangeLog: * bsd-kvm.o: Define _KMEMUSER. * configure.ac: Define _KMEMUSER when checking for "struct lwp". * configure: Regenerate. --- gdb/ChangeLog | 6 ++++++ gdb/bsd-kvm.c | 1 + gdb/configure | 1 + gdb/configure.ac | 1 + 4 files changed, 9 insertions(+) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 74b5d8f8da1..0d86e4705e0 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,9 @@ +2017-09-04 John Baldwin + + * bsd-kvm.o: Define _KMEMUSER. + * configure.ac: Define _KMEMUSER when checking for "struct lwp". + * configure: Regenerate. + 2017-09-04 John Baldwin * amd64-fbsd-nat.c: Add include of "x86-xstate.h". diff --git a/gdb/bsd-kvm.c b/gdb/bsd-kvm.c index 98e242836d9..8c2139462dc 100644 --- a/gdb/bsd-kvm.c +++ b/gdb/bsd-kvm.c @@ -17,6 +17,7 @@ You should have received a copy of the GNU General Public License along with this program.
