Subject: [Qemu-devel] [PULL 3/4] configure: use valid args testing sem_timedwait
Date: Wed, 26 Jun 2019 22:02:51 +0200 [thread overview]
Message-ID: <20190626200252.30220-4-laurent@vivier.eu> (raw)
In-Reply-To: <20190626200252.30220-1-laurent@vivier.eu>
From: Daniel P. Berrangé <berrange@redhat.com>
The sem_timedwait function has been annotated as requiring
non-null args in latest header files from GCC snapshot
representing the future 2.30 release.
This causes configure to fail when -Werror is used:
config-temp/qemu-conf.c: In function ‘main’:
config-temp/qemu-conf.c:2:25: error: null argument where non-null required (argument 1) [-Werror=nonnull]
2 | int main(void) { return sem_timedwait(0, 0); }
| ^~~~~~~~~~~~~
config-temp/qemu-conf.c:2:25: error: null argument where non-null required (argument 2) [-Werror=nonnull]
