C11 GCC threads.h not found?
c, c11, multithreading
Solution
The `gcc` document C11 status indicates that it does not support threading, it says:
Threading [Optional] | Library issue (not implemented)
As the document indicates this is not really a `gcc` or `clang` issue but `glibc` issue. As Zack pointed out it looks like there may be work under way soon to get support for this into `glibc` but that won't help you now. You can use this in the meantime.
Fixed for glibc 2.28
According the Bug 14092 - Support C11 threads this is fixed in glibc 2.28:
Implemented upstream by:
9d0a979 Add manual documentation for threads.h 0a07288 nptl: Add test cases for ISO C11 threads c6dd669 nptl: Add abilist symbols for C11 threads 78d4013 nptl: Add C11 threads tss_* functions 918311a nptl: Add C11 threads cnd_* functions 3c20a67 nptl: Add C11 threads call_once functions 18d59c1 nptl: Add C11 threads mtx_* functions ce7528f nptl: Add C11 threads thrd_* functions
It will be included in 2.28.
Problem
The following code ``` #include <threads.h> ``` Gives me this error: ``` fatal error: threads.h: No such file or directory ``` Using the latest GCC and Clang with -std=c11. Is C11 threading not supported by GCC and Clang? Or is there a hack (or something to install) to get it? I'm just using Ubuntu 14.04 with the gcc and clang packages from the Ubuntu repo.
