If there has to be interactive GUI then i somehow prefer Qt to
MS GUI and OpenGL to DirectX. Compiles and works with MSVC. Also
friendly i(something) and Linux addicts are lot happier with my
code. ;)
That sort of misses the point. You still need to ask for GUI subsystem when you
build that app for Windows. Unless you want a console window popping up...
Yes, i may want it to be there (popping up can be avoided by hiding
it),
Ah.
because without console the cin, cerr and cout go to god knows
where in Windows.
Well, in addition to God, you might ask me. :-) By default they go nowhere. But
they can be redirected, by the ordinary redirection operators.
Actually I have seen (portable to Linux and Mac)
code that has gone full round:
int main( int argc, char *argv[] ) {
Configuration::Load( argc, argv );
#if defined(_MSC_VER)
BOOL ok = ::AllocConsole();
"If the compiler is MSVC, allocate a console window". Hm. You better inform
those folks that they're doing meaningless things.
// ... mess with screen buffers of console
// ... redirect std streams to console
#endif
return Session::run( argc, argv );
}
"Full round" in sense that they had /subsystem:windows and they had
int main() and now what was missing was console.
That's my preference. An ordinary GUI subsystem app, with a standard `main`. Why
write more to get non-standard code? That's just silly. It's like writing `void
main`, one character more, just to get a non-standard idiot's[1] version.
Also the solution to
their issue was not as stupid as it feels. It sort of supports your
point, sort of argues with it and sort of misses it too. ;) The real
reasons behind the mess are in Windows architecture, the MS compiler
team feels to consist of decent specialists.
There's no mess wrt. this in the Windows architecture.
To wit, the MinGW g++ compiler / toolchain does not have this problem.
Technical: `main` and `wMain` and `winMain` and `wWinMain` are not supported at
the Windows API level (disregarding the MSVC runtime as part of the API).
Cheers & hth.,

Notes:
[1] When I'm writing "idiot's" that's just an exaggeration to put it to a point.
For example, Bjarne used that `void main` at least once in the second edition of
The C++ Programming Language, and I'm not calling him an idiot. :-)
