C++11 thread_local in gcc - alternatives

Question

As I can see at: http://gcc.gnu.org/projects/cxx0x.html thread_local keyword is unfortunately unsupported in gcc yet.

Are there any alternatives for that? I don't want to use boost library.

Answer 1

The gcc compiler has a storage class __thread that might be close enough.

Answer 2

According to this GCC documentation page, you should try to use __thread as a qualifier (like volatile or const are) for your thread local storage.

Answer 3

GCC 4.8.0 includes support for the thread_local storage class.
