From: Max Filippov Date: Wed, 12 Dec 2018 15:13:14 +0000 (-0800) Subject: package/uclibc: add custom bits/poll.h for xtensa X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=95f11fb25d68a5b92426710eeeb0841771d151a4;p=buildroot.git package/uclibc: add custom bits/poll.h for xtensa Definitions of POLLWRNORM, POLLWRBAND and POLLREMOVE in xtensa linux kernel are non-standard. Provide bits/poll.h with correct values for these constants for uclibc-ng. 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"); ^~~~~~~~~~~~~ Fixes: http://autobuild.buildroot.net/results/5a0112b7a2c81fa5253c9adc93efe415256cd811 Signed-off-by: Max Filippov Reviewed-by: Baruch Siach Signed-off-by: Thomas Petazzoni --- diff --git a/package/uclibc/0002-xtensa-add-custom-bits-poll.h.patch b/package/uclibc/0002-xtensa-add-custom-bits-poll.h.patch new file mode 100644 index 0000000000..030938bbcd --- /dev/null +++ b/package/uclibc/0002-xtensa-add-custom-bits-poll.h.patch @@ -0,0 +1,93 @@ +From 0cae9700a4a421dc22c80d205fbae4d01fdd1356 Mon Sep 17 00:00:00 2001 +From: Max Filippov +Date: Wed, 12 Dec 2018 06:58:01 -0800 +Subject: [PATCH] xtensa: add custom bits/poll.h +MIME-Version: 1.0 +Content-Type: text/plain; charset=UTF-8 +Content-Transfer-Encoding: 8bit + +Definitions of POLLWRNORM, POLLWRBAND and POLLREMOVE in xtensa linux +kernel are non-standard.
