Well actually, maybe saying that threading isn't activated is not the correct way to describe my problem. I am basically trying to take advantage of the C++0x implementation provided by GCC 4.4 through the <thread> header for example. The GCC 4.4 implementation of std::thread is guarded by the following preprocessing directive:
#if defined(_GLIBCXX_HAS_GTHREADS) && defined(_GLIBCXX_USE_C99_STDINT_TR1) When looking at the bits/c++config.h, _GLIBCXX_USE_C99_STDINT_TR1 is defined but _GLIBCXX_HAS_GTHREADS isn't. I know that GCC has its own implementation of threads called gthreads (that std::thread relies on) which itself is a wrapper around POSIX threads (or other flavours depending on configuration). Either I am not passing the correct flags to GCC (in addition to the -std=c++0x) or my installation of gcc is not correct, or last possibility, my GCC build configuration is not correct. Thanks, O.
