7// cdstd.h: define macros to select library API version.

9// This must be included before all library #includes.
10// Typically this done as part of cddefines.h, only required
11// independently when cddefines.h is not first include.

13// We *require* POSIX.1-2008 as a minimum (for strnlen()).
14// See e.g. Rochkind, Advanced UNIX Programming for more details.
15
16// There appears to be a bug in the POSIX implementation in FreeBSD that was
17// imported into Apple Darwin (at least version 11.4.2) where defining _POSIX_SOURCE
18// will cause compilation errors as a result of missing type definitions (e.g., u_int)
19// when including certain system header files. See e.g. this report:
20// http://lists.freebsd.org/pipermail/freebsd-bugs/2011-April/044049.html
21#if !defined(__APPLE__) && !defined(__FreeBSD__) && !defined(_POSIX_SOURCE)

26// Cloudy requires C++11, and we specify this using the -std=c++11 compiler flag.
27// However, cpp versions prior to 6.1.0 have a bug that causes the __cplusplus flag
28// to have inconsistent values during compilation, causing compilation errors, e.g.
29// when including <array>. The following hack works around that...
30#if __cplusplus < 201103
31#undef __cplusplus
32#define __cplusplus 201103

39// the Intel MPI implementation wants this file included before cstdio...
40// http://www.saii.ull.es/files/doc_intel/doc/HelpMe_FAQ.htm
41// so we include it here to make really sure that it is in front of
42// the system includes that may be done before cddefines.h is included
43//
44// we define OMPI_SKIP_MPICXX to silence compiler warnings/errors about a
45// poorly designed C++ interface in openmpi, see this thread for more details:
