Summary0014685: cmake-gui does not display text in console
DescriptionCmake-gui does not display any text in a windows console.
Steps To Reproduce1. Start console: cmd.exe.
2. Execute: cmake-gui --help.
Additional InformationI expect the help text to be displayed, just like cmake does.
Instead nothing seems to happen, no gui, no help text.

Running: cmake-gui --help cmake-help.txt creates the file with the expected text. I was looking for the command-line parameters (-H and -B).


Probably the cause is that when writing to the console in a Qt GUI project (in windows 8.1) the text is not written to the parent console. Redirecting the text works.

To attach to the parent console I once did (when not starting the gui):
AttachConsole(-1);freopen("CONOUT$", "w", stdout);
But this leaves the console open...

This seems a bit difficult. I happened to experiment with this using Visual Studio 11. I wanted to make sure that redirection to a file would keep working (cmake-gui --help > help.txt).

To redirect to the console, we need to do freopen(), but only if it isn't redirected to a file.

_fileno(stdout) might give some indication of this because it is supposed to return -1 or -2 for non-gui apps, and I assume that it does so if there is no redirection.
But _fileno(stdout) is broken under some versions of Visual Studio.

So, I don't yet see a robust way to do this.
Do you have a suggested patch to cmake-gui?
