Hi,
VS2015 allows to disable the C++ library features deprecated in C++11:
[1] "By default, we provide auto_ptr/etc. If you define _HAS_AUTO_PTR_ETC to 0
project-wide (which you should do via the command line or project file,
not via #define), then we won't provide auto_ptr/etc."
Attempt to compile the following test.cpp based on up-to-date Boost
(master) fails:
#include
int main() { return 0; }
cl /EHsc /ID:\dev\boost.git /D_HAS_AUTO_PTR_ETC=0 test.cpp
Below are two problems that can be solved with additional define of
BOOST_NO_AUTO_PTR=1
D:\dev\boost.git\boost/get_pointer.hpp(48): error C2065: 'auto_ptr':
undeclared identifier
D:\dev\boost.git\boost/get_pointer.hpp(62): error C2923:
'std::unique_ptr': 'T' is not a valid template type argument for
parameter '_Ty'
I also expected _HAS_AUTO_PTR_ETC=0 should imply BOOST_NO_AUTO_PTR=1.
Then, I hoped this would work:
cl /EHsc /ID:\dev\boost.git /D_HAS_AUTO_PTR_ETC=0 /DBOOST_NO_AUTO_PTR=1 test.cpp
Unfortunately, it fails due to uses of std::unary_function and
std::binary_function
in boost/algorithm/string/detail/case_conv.hpp. Those functions have
been deprecated
since C++11 and are disable by _HAS_AUTO_PTR_ETC=0.
This basic evaluation made me wonder, does Boost support compilation
with _HAS_AUTO_PTR_ETC=0 defined at all?
