CCS/AM3358: GCC C/C++ Float Printing Support for Sitara

Hi,

is it possible to enable float support for the GCC/Sitara toolchain for float to string conversion via

    std::string buf;
    std::stringstream sbuf(buf);
    sbuf << 1.34 << std::endl;

std::string x = std::to_string(1.23);

char buf[25] = {'\0'};
sprintf(buf, "test: %.1f", 1.234);

I'm working with

Those are standard features of C++. As such, they are supported. What happens when you try it?

Be sure you have allocated enough memory for the stack and the heap. These operations use lots of stack and heap.

Thanks and regards,

I haven't checked if the same technique works for the C++ formatted output.

Thanks a lot, the

--undefined,_printf_float

flag solved my issue.

Both, the sprintf and the C++ stringstream work now with floats.
