I'm working with a library that has a class that throws in its dtor. It dates back to the 1990s, so we are paying the tax now... According to GCC 4.6 release notes (https://gcc.gnu.org/gcc-4.6/changes.html), GCC got noexcept in 4.6. However, I'm testing the change under MinGW with the 4.8.1 compiler. Its resulting in: g++ -DNDEBUG -g2 -O3 -march=native -Wall -Wextra -Wno-type-limits -Wno-unknown-pragmas -pipe -c algparam.cpp In file included from algparam.cpp:7:0: algparam.h:262:2: warning: identifier 'noexcept' is a keyword in C++11 [-Wc++0x- compat] virtual ~AlgorithmParametersBase() CRYPTOPP_THROW ^ algparam.h:262:35: error: expected ';' at end of member declaration virtual ~AlgorithmParametersBase() CRYPTOPP_THROW ^ In file included from pch.h:10:0, from algparam.cpp:3: config.h:519:34: error: expected identifier before 'false' # define CRYPTOPP_THROW noexcept(false) ^ algparam.h:262:37: note: in expansion of macro 'CRYPTOPP_THROW' virtual ~AlgorithmParametersBase() CRYPTOPP_THROW ^ config.h:519:34: error: expected ',' or '...' before 'false' # define CRYPTOPP_THROW noexcept(false) GCC does not appear to define __cplusplus under MinGW, so I can't perform the test __cpluplus >= 201103L. $ g++ -dM -E - < /dev/null | grep cplusplus $ $ g++ -std=c++11 -dM -E - < /dev/null | grep cplusplus cc1.exe: warning: command line option '-std=c++11' is valid for C++/ObjC++ but not for C [enabled by default]= How do I test for the noexcept feature?
