铛C11 threads.h未找到 [英] clang c11 threads.h not found

问题描述

我试图建立以x code一C11线程的例子...但它似乎不具备threads.h头，虽然它不是complaning这里描述的宏：结果

I am trying to setup a c11 thread example in xcode... but it doesn't seem to have the threads.h header, though it isn't complaning about the macro described here:
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf

__ STDC_NO_THREADS__The整型常量1，意在表明该实现不支持的＆lt;＆threads.h GT;头。

__STDC_NO_THREADS__The integer constant 1, intended to indicate that the implementation does not support the <threads.h> header.

推荐答案

通过我的机器上铛（诉3.2在Ubuntu / Linux）的该功能测试宏没有定义。该功能支持将需要在C库的支持，这通常不来与编译器。所以基本上对铛答案不会比GCC很大的不同，他们通常建立在相同的C库，即glibc的，看的这里的答案GCC 。

With the clang on my machine (v. 3.2 on ubuntu/linux) that feature test macro isn't defined. Support for that feature will need support in the C library, that usually doesn't come with the compiler. So basically the answer for clang will not be much different than for gcc, they usually build upon the same C library, namely glibc, see here for answer for gcc.
