In the deeply -embedded world, that is probably all that is necessary. If you -have a need for more extensive C++ support, the following libraries -are recommended: - - - libstdc++ (part of GCC) - - STLport http://www.stlport.org/ - - uClibc++ http://cxx.uclibc.org/ - - uSTL http://ustl.sourceforge.net/ - -There is a version of uClibc++ that is customized for NuttX that can -be found here: misc/uClibc++. See misc/uClibc++ for installation -instructions. - -At present, only the following are supported here: - - - void *operator new(std::size_t nbytes); - - void operator delete(void* ptr); - - void operator delete[](void *ptr); - - void __cxa_pure_virtual(void); - - int __aeabi_atexit(void* object, void (*destroyer)(void*), void *dso_handle); - - int __cxa_atexit(__cxa_exitfunc_t func, FAR void *arg, FAR void *dso_handle); - -operator new ------------- - - This operator should take a type of size_t. But size_t has an unknown underlying - type. In the nuttx sys/types.h header file, size_t is typed as uint32_t - (which is determined by architecture-specific logic). But the C++ - compiler may believe that size_t is of a different type resulting in - compilation errors in the operator. Using the underlying integer type - instead of size_t seems to resolve the compilation issues. Need to - REVISIT this. - - Once some C++ compilers, this will cause an error: - - Problem: "'operator new' takes size_t ('...') as first parameter" - Workaround: Add -fpermissive to the compilation flags |
