Hello,
I test currently the GCC 4.9 release branch. Should <stdatomic.h> work
with C++? I use GCC as a cross-compiler for RTEMS targets. RTEMS uses
Newlib as C library. I ported the FreeBSD version of <stdatomic.h> to
Newlib and use this successfully with C/C++ and GCC pre-4.9 versions.
Now with GCC 4.9 I have the problem that two <stdatomic.h> files are
installed, e.g.
find /opt/rtems-4.11/ -name stdatomic.h
/opt/rtems-4.11/lib64/gcc/sparc-rtems4.11/4.9.0/include/stdatomic.h
/opt/rtems-4.11/sparc-rtems4.11/include/stdatomic.h
The first is provided by GCC, the second by Newlib. The GCC version is
the one used. Now I get this when I compile a C++ source which
indirectly includes <stdatomic.h>:
sparc-rtems4.11-g++ -std=c++11 somefile.cc
/opt/rtems-4.11/lib64/gcc/sparc-rtems4.11/4.9.0/include/stdatomic.h:40:9: error:
'_Atomic' does not name a type
typedef _Atomic _Bool atomic_bool;
Is this working as intended?
