C++ operator new missing?

[kaido42]

in cpp demo, adding

B *test = new B

causes the following error during lnking:

demo\cpp/src/demo_cpp.cpp:79: undefined reference to 'operator new(unsigned int)'

in another project I was trying to use C++, I'm getting the following:

LD                kala.elf
mips-elf-ld: section .gcc_except_table.kalaSoundInit loaded at [ffffffff882490e0,ffffffff882490ef] overlaps section .cust_data loaded at [ffffffff882490e0,ffffffff882490ef]

please help.

I am facing same isssue , any suggestion how to utilise C++ library ?

void * operator new(size_t size) { return OS_Malloc(size); }

void operator delete(void * ptr) { OS_Free(ptr); } You can use this functions. I got new error "unwind_value"
