How do I configure CLion standard console output?

问题

Problem: CLion doesn't output any console output for debugging purposes.

I'm using CLion with the MingW compiler and cmake. No matter whether I use:

std::cout << "Testing" << std::endl;

Or:

printf("Testing");

I don't see any console output.

Attempts at Resolution:

1: I've checked "Run", "Debug", "Terminal" and "Cmake". I've attempted to edit my configurations but "Debug" doesn't show up.

2: Next, I went to Settings->Build,Execution,Deployment->CMake to edit the Generation types. I added Debug and RelWithDebInfo and still to no avail.

3: I also attempted to add "-Debug" to Cmake, but I still have no output.

4: The closest thing I've received for debugging is using GDB to view variable values at break points. This only works in the "RelWithDebInfo" generation.

Solution:

I ended up figuring out what the problem was.

I'm developing a Qt GUI application within CLion on Windows. You have to specify a console for console output to print onto.

Call this Console() function early in your main for a console prompt to open up. Now, whenever you run

QDebug() << <string>;

std::cout << <string> std::endl;

You'll see your debugging statements. Hope this helps somebody else out there with the same problem.

Code:

void Console()
{
    AllocConsole();
    FILE *pFileCon = NULL;
    pFileCon = freopen("CONOUT$", "w", stdout);

    COORD coordInfo;
    coordInfo.X = 130;
    coordInfo.Y = 9000;

    SetConsoleScreenBufferSize(GetStdHandle(STD_OUTPUT_HANDLE), coordInfo);
    SetConsoleMode(GetStdHandle(STD_OUTPUT_HANDLE),ENABLE_QUICK_EDIT_MODE| ENABLE_EXTENDED_FLAGS);
}
