I am having trouble using the Atomic-Builtins in minGW. In particular I get that __sync_fetch_and_or, __sync_fetch_and_and and __sync_bool_compare_and_swap are said to be undefined when linking. Do I need some extra library or what? I updated minGW to the latest I could (gcc4.6) ==John ffitch ------------------------------------------------------------------------------ Symantec Endpoint Protection 12 positioned as A LEADER in The Forrester Wave(TM): Endpoint Security, Q1 2013 and "remains a good choice" in the endpoint security space.

The sourceforge download page seems to provide gcc 4.7: On 10 Mar 2013, at 15:53, Victor Lazzarini wrote:

In MinGW 4.6.2, these functions are builtins. SContruct for Csound5 tests for them and finds them.

Wait a minute, I was going too fast. These builtins may be only in 4.7 and not in 4.6. I am checking... There is a bug report at http://sourceforge.net/p/mingw/bugs/1585/ that seems related (it's for C++ not C). I tried the test program for the bug report and get undefined symbols here as well. I am going to try 4.7 now, and will advise how I installed it. Regards, Mike On Sun, Mar 10, 2013 at 12:07 PM, Michael Gogins <michael.gogins@gmail.com> wrote:
