std::thread in Dev C++ 5.5.3

[Alby94]

When I insert a thread in my code...the compiler reports me an error:
"'thread' is not a member of std".

I alredy activated the standard language -std=c++0x in the options..

it sounds like you might want to upgrade your compiler.

Also, on windows, only some toolchains actually have thread support at all (Win32 threads isn't supported, you need POSIX threading for MinGW, for example). A good compiler that does support threading is TDM-GCC (>= 4.8).

i try to use the header ptrhead.h for create many threads...but the linker reports me this:
undefined reference to `__imp_pthread_create'... how to fix it?
