Python include warnings
|
|
===============================
|
|
|
|
Very often compile warnings of Python can be seen, something like ::
|
|
|
|
/usr/local/install/python-2.7.5/include/python2.7/pyconfig.h:1173:0: warning: "_POSIX_C_SOURCE" redefined [enabled by default]
|
|
#define _POSIX_C_SOURCE 200112L
|
|
^
|
|
In file included from /usr/local/install/gcc-4.8.1/include/c++/4.8.1/x86_64-unknown-linux-gnu/bits/os_defines.h:39:0,
|
|
......
|
|
/usr/include/features.h:162:0: note: this is the location of the previous definition
|
|
# define _POSIX_C_SOURCE 200809L
|
|
...
|
|
#define _XOPEN_SOURCE 600
|
|
|
|
|
|
It is due to the fact that Python.h must be included
|
|
before some other headers (cf python documentation).
|
|
|
|
Solutions:
|
|
|
|
#. include first some triqs library, like arrays.hpp, gfs.hpp, etc...
|
|
|
|
#. include first <utility/first_include.hpp>
|
|
that conditionally includes python if python is to be supported.
|
|
(used by all triqs libs, hence the first point).
