Bug #: 53061
Summary: Stop assuming NULL for C++ is an integral type
Classification: Unclassified
Product: LibreOffice
Version: unspecified
Platform: All
OS/Version: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Libreoffice
AssignedTo: [email protected]
ReportedBy: [email protected]
Now LibreOffice uses gnu++0x mode for C++ compilation if available, we should
stop assuming NULL for C++ is an integral type (e.g., 0L) because some
platforms rightfully define it as nullptr. For example, recent FreeBSD defines
NULL like this:
#if !defined(__cplusplus)
#define NULL ((void *)0)
#else
#if __cplusplus >= 201103L
#define NULL nullptr
#elif defined(__GNUG__) && defined(__GNUC__) && __GNUC__ >= 4
#define NULL __null
#else
#if defined(__LP64__)
#define NULL (0L)
#else
#define NULL 0
#endif /* __LP64__ */
#endif /* __GNUG__ */
#endif /* !__cplusplus */
With GCC 4.7+ (and Clang 3.2+), __cplusplus is correctly defined as 201103L and
it is causing lots of build issues with these new C++ compilers.
