Subject: [boost] [boost config] BOOST_NO_CXX11_HDR_CODECVT question
From: Robert Ramey (ramey_at_[hidden])
Date: 2014-11-26 13:32:56
I'm building on Mac OS with Xcode. The following test program seems to
demonstrate a problem either with config or my understanding of it.
<code>
#include <codecvt>
#include <boost/config.hpp>
#ifdef BOOST_NO_CXX11_HDR_CODECVT
#pragma message "no C++ codevt support"
#endif
#include "../../../libs/config/test/config_info.cpp"
</code>
When I compile the following I get a compile time message "no C++ codevt
support" which is NOT what I expect to see. This surprises me since if the
message is correct, I would expect the compile would fail at that #include
<codecvt> statement.
When I run the program I get:

implements all of C++11 library standard
Any help appreciated,
