This could be that the test machine is misconfigured, or that atomic_count.hpp needs a patch for this version of GCC.
GCC 4.3 has moved this header into ext/atomicity.h and all of its functions into namespace __gnu_cxx.
For GCC 4.1 and above, we need to switch atomic_count and sp_counted_base to
http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc/Atomic-Builtins.html
If someone can submit a patch for that I'll incorporate it, otherwise it will happen whenever I find the time to implement and test it myself.
Please note that if the target platform is not supported with these extensions, the compiler will generate external function call which will most likely result in link errors. For example, I tried to make use of them under Cygwin (I was hoping they would do just like interlocked functions) and got this problem. -- Best regards, Andrey mailto:andysem@mail.ru
