From c7151401e09b677559b5f280c2b4e8b0b8d33a41 Mon Sep 17 00:00:00 2001 From: Jon Turney Date: Thu, 9 Jun 2016 18:21:35 +0000 Subject: Disable use of weak in threads_posix.h on Cygwin Weak doesn't work the same on PE/COFF as on ELF, they are only weak references. Specifically, since nothing else pulls in the object which contains pthread_mutexattr_init() (and coming from the C library, that is the only thing that object contains), means that it ends up as 0 Signed-off-by: Jon Turney --- include/c11/threads_posix.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'include') diff --git a/include/c11/threads_posix.h b/include/c11/threads_posix.h index 61b7fabf637..43e803ee8d1 100644 --- a/include/c11/threads_posix.h +++ b/include/c11/threads_posix.h @@ -184,7 +184,7 @@ mtx_destroy(mtx_t *mtx) * Thus the linker will be happy and things don't clash when building * with -O1 or greater. */ -#ifdef HAVE_FUNC_ATTRIBUTE_WEAK +#if defined(HAVE_FUNC_ATTRIBUTE_WEAK) && !defined(__CYGWIN__) __attribute__((weak)) int pthread_mutexattr_init(pthread_mutexattr_t *attr); -- cgit v1.2.3
