IIUC, that symbol demangles to:
std::basic_filebuf<char, std::char_traits<char> >::open(wchar_t const*, std::_Ios_Openmode)
That is a symbol that should be exported by the standard libraries.
It looks like you copied some (but not all) necessary libraries to a different folder with the executable. Either, copy the standard libraries to that folder, too, or try compiling with `-static-libstdc++` to check if that makes a difference.
mkoctfile --link-stand-alone embedded_ashwin.cc -o embedded.exe -static-libstdc++
Please note that although the screenshot says callOctave.exe, inside it is the same embedded.cc program. I thought of clarifying.
When I execute the program using .exe created using mkoctfile --link-stand-alone embedded.cc -o embedded.exe
I get the following error. My computer is Windows 10, Gnu Octave v6.4.0. This was working in the previous version v 6.2.0. Could you please guide.
