Subject: [Qemu-devel] [PULL 3/3] w32: Use gcc option -mthreads
Date: Mon, 30 Nov 2015 06:55:55 +0100 [thread overview]
Message-ID: <1448862955-22955-4-git-send-email-sw@weilnetz.de> (raw)
In-Reply-To: <1448862955-22955-1-git-send-email-sw@weilnetz.de>
QEMU uses threads / coroutines, therefore support for thread local storage
and thread safe libraries (-D_MT) must be enabled by using -mthreads.
