Given the name clash it is an easy mistake to make, but your test has nothing to do with glib, which is a C library providing cross-platform support for various programming utilities (and which is connected with the GTK+ UI toolkit). Instead it is an indication of whether your g++/libc implementation supports threads for the particular gcc distribution in question. Clearly yours doesn't. You probably need to get a different MinGW package. Beyond that I cannot help, as I have never used MinGW. Chris |

A modified version of your original example: ____________________________________________________________ #include <iostream> // std::cout #include <thread> // std::thread, std::this_thread::sleep_for #include <chrono> // std::chrono::seconds static thread_local int g_tls = 0; void pause_thread_call() { std::cout << "pause of " << g_tls << " seconds ended\n"; } void pause_thread(int n) { g_tls = n; std::this_thread::sleep_for(std::chrono::seconds(n)); pause_thread_call(); } int main() { std::cout << "Spawning 3 threads...\n"; std::thread t1(pause_thread, 1); std::thread t2(pause_thread, 2); std::thread t3(pause_thread, 3); std::cout << "Done spawning threads. Now waiting for them to join:\n"; t1.join(); t2.join(); t3.join(); std::cout << "All threads joined!\n"; return 0; } ____________________________________________________________ ;^) |

I forgot to post the darn link: First, think about getting a windows live account which is required to activate the product. Then go here: https://www.visualstudio.com Click on the green button that says free in the upper right hand corner of the screen. Actually, msvc 2013 is not all that bad. Its debugger happens to be very nice. |

Simple example, I cannot get `_Thread_local' to work, however `thread_local' works fine... damn. |

MSVC 2013 does appear to support the `thread_local' keyword. There is a rather ugly workaround, something like: ________________________________________________ // `thread_local' keyword "workaround" for MSVC, damn! #if defined (_MSC_VER) # if (_MSC_VER <= 1800) # define thread_local_storage __declspec(thread) # else // assume more recent versions of msvc has `thread_local'... # define thread_local_storage thread_local # endif #else # define thread_local_storage thread_local
