From 308746ac207de4f1c3429d6e61ff071809378b70 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Mon, 26 Oct 2020 22:10:02 -0700 Subject: [PATCH] Define __NR_futex if it does not exist __NR_futex is not defines by newer architectures e.g. arc, riscv32 as they only have 64bit variant of time_t. Glibc defines SYS_futex interface based on __NR_futex, since this is used in applications, such applications start to fail to build for these newer architectures. This patch defines a fallback to alias __NR_futex to __NR_futex_tim64 so SYS_futex keeps working Upstream-Status: Pending Signed-off-by: Khem Raj --- src/corelib/thread/qfutex_p.h | 3 +++ 1 file changed, 3 insertions(+) diff --git a/src/corelib/thread/qfutex_p.h b/src/corelib/thread/qfutex_p.h index f287b752d7..fa5307a604 100644 --- a/src/corelib/thread/qfutex_p.h +++ b/src/corelib/thread/qfutex_p.h @@ -76,6 +76,9 @@ QT_END_NAMESPACE # include # include # include +# if !defined(__NR_futex) && defined(__NR_futex_time64) +# define __NR_futex __NR_futex_time64 +# endif # define QT_ALWAYS_USE_FUTEX // if not defined in linux/futex.h
