How can I detect g++ and MinGW in C++ preprocessor?
提问by EddieV223
I want to do something like:
我想做类似的事情:
#ifdef GCC
#define GetFunctionName() string("My function name is ") + __PRETTY_FUNCTION__;
#endif
Since I want to use pretty PRETTY_FUNCTIONthis is only supported by gnu as far as I know so I need to detect if I am compiling for g++ and MinGW, how can I do that? I'm guessing all I need to know are the compiler's preprocessor definitions, like I did for Microsoft below.
由于我想使用漂亮的PRETTY_FUNCTION,据我所知,这只受 gnu 支持,所以我需要检测我是否正在为 g++ 和 MinGW 进行编译,我该怎么做?我猜我需要知道的只是编译器的预处理器定义,就像我在下面为 Microsoft 所做的那样。
#ifdef WIN32
#define LogFuncBegin() gLogger.FuncBegin( __FUNCTION__ );
#define LogFuncEndSuccess() gLogger.FuncEndSuccess( __FUNCTION__ );
#endif

For GCC:
对于海湾合作委员会:
#ifdef __GNUC__
For MinGW:
对于 MinGW:
#ifdef __MINGW32__
x86_64-w64-mingw32-gcc defines both __MINGW32__
and __MINGW64__
.
x86_64-w64-mingw32-gcc 定义了__MINGW32__
和__MINGW64__
。
