Does any C library implement C11 threads for GNU/Linux?
c, c11, multithreading
Solution
musl now (as of Sep 2014-ish) implements C11 threads!
According to this recent musl mailing list post and other conversation on that list in Jul-Sep 2014, it appears that the musl library now (as of 2014-09-07) implements the C11 threads interface, though the comparison chart; does not as of this writing reflect this.
Since this question is re-opened, I moved this content to a proper answer.
Problem
There have been a lot of questions about C11 and C11 threading, but I don't see a definitive answer anywhere: Does any C library implement the C11 threading interface usable on GNU/Linux-like? e.g., provide the "optional" `<threads.h>` and the thread support library like `thrd_create()`, from the C11 standard near p. 376. Ideally, I'd like to find a library that is common-ish, open-source or free, for common/generic/multi architecture (e.g., GNU/Linux, x86_64, or portable-ish). A few of the more helpful and relevant SO links: - this one and this one on `glibc`; - this one that's talking about the standard; - this one about `clang`; - this one about C11 in general and this one about Windows and other platforms; - a lot more about C++11 threading, but I am only interested in C11. Some non-starter options for libraries: - `glibc` library does not; there is an open bug since 2012; there was GSoC proposal but seems not accepted; - LLVM/Clang project does not have a C library; - musl library does not; -- now does! See edit below and answer. - Newlib library supports threading (docs), but not using `pthread` nor C11 threads; - uClibc does not; - this comparison chart, which is dubious (e.g., I see no evidence in musl sources for C11 thread-local storage support); - Some various posts about BSD, - Pelles, which appears closed and Windows-only. I am not interested in POSIX threads (many fine options), Windows, an IDE, nor C++11 (I know that GNU `libstdc++` and LLVM/Clang `libc++` provide C++11's `std::thread`, which uses `-pthread`) Thanks! (re-)Edit: question re-opened, so migrated content to answer to clean up.
