I have a .cpp file which has usage of *NULL* at several places. When I try to compile this cpp file for Android/x86 platform using clang++ on Windows machine + standalone tool chain, I am running into "expected expression" error at the places where *NULL* is used. I find the definition of *NULL* in stddef.h of clang headers provided by Android NDK as below.
#if defined(__need_NULL)#undef NULL#ifdef __cplusplus# if !defined(__MINGW32__) && !defined(_MSC_VER)# define NULL __null# else# define NULL 0# endif#else# define NULL ((void*)0)#endif As far as I know, __null is specific to GNU compiler. In my case both _MSC_VER and __MINGW32__ are undefined because I am compiling for Android platform using clang++ and standalone tool chain. So it is hitting into define NULL __null. Since clang++ has no clue of what __null is, it is resulting into "expected expression" error. My question is, why is clang using macros(like __null) provided by GNU compiler? Or am I missing something here? Could somebody please help me understand. Thanks
