Definitions of POLLWRNORM, POLLWRBAND and POLLREMOVE in xtensa linux kernel are non-standard. Provide bits/poll.h with correct values for these constants. This fixes the following strace build errors: In file included from xlat/pollflags.h:4:0, from poll.c:34: ./static_assert.h:40:24: error: static assertion failed: "POLLWRBAND != 0x0100" # define static_assert _Static_assert ^ xlat/pollflags.h:75:1: note: in expansion of macro ‘static_assert’ static_assert((POLLWRBAND) == (0x0100), "POLLWRBAND != 0x0100"); ^~~~~~~~~~~~~ ./static_assert.h:40:24: error: static assertion failed: "POLLREMOVE != 0x0800" # define static_assert _Static_assert ^ xlat/pollflags.h:117:1: note: in expansion of macro ‘static_assert’ static_assert((POLLREMOVE) == (0x0800), "POLLREMOVE != 0x0800"); ^~~~~~~~~~~~~ Signed-off-by: Max Filippov &lt;jcmvbkbc(a)gmail.com&gt; --- libc/sysdeps/linux/xtensa/bits/poll.h | 49 +++++++++++++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 libc/sysdeps/linux/xtensa/bits/poll.h diff --git a/libc/sysdeps/linux/xtensa/bits/poll.h b/libc/sysdeps/linux/xtensa/bits/poll.h new file mode 100644 index 000000000000..4588cc326006 --- /dev/null +++ b/libc/sysdeps/linux/xtensa/bits/poll.h @@ -0,0 +1,49 @@ +/* Copyright (C) 1997, 2001, 2006 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
