c++ emulation issue with std::cout << "Hello World!\n";

[decustom]

I get an error while emulating following MSVC++ code on Linux: std::cout << d << " Hello World!\n";
However, if I change to use printf("%d Hello World!\n", d); it is able to emulate!

Need to debug more too see the actual issue.

Well, Windows always a myth and windows + MSVC. i guess we are lost.

[xwings]

update issue #333 , we should support C++

[learn-more]

This is going to be a huge set of functions to support.
BTW this specific function translates to:
public: class std::basic_ostream<char,struct std::char_traits<char> > & __ptr64 __cdecl std::basic_ostream<char,struct std::char_traits<char> >::operator<<(__int64) __ptr64

Close for now.

We updated the codebase for Qiling and Unicorn since this issue being posted.

Feel free to try the latest version.
