I'm trying to build OpenMPI with CMake under MinGW-w64 based on GCC
4.8.0 (POSIX Threads), and here is what I get:
In file included from ../opal/threads/mutex_windows.h:36:0,
../opal/include/opal/sys/atomic.h:577:2: error: #error Atomic arithmetic
on pointers not supported
#error Atomic arithmetic on pointers not supported
ninja: build stopped: subcommand failed.
