SDL and ALUT on Windows: "stdin Bad file descriptor"

I'm trying SDL on Windows, and things are getting really weird.
I can compile the code (links on the end).
When I run it, if I try using `stdin` the program crashes with this message: 

<stdin>: hGetLine: invalid argument (Bad file descriptor)

Is it something to do with SDL itself?
What am I doing wrong? :(


Thanks.

You haven't even touched SDL at that point in that source code.

If I had to guess, something (possibly a linker option embedded in the SDL binding) is causing your program to be built as a Windows GUI (as opposed to Windows Console) so it has no stdin.  I couldn't tell you much more than that, though; the ways of Windows development are foreign to me.

You probably used -optl-mwindows in the compile command, to prevent the  
DOS-shell appearing behind your window.

Re: SDL and ALUT on Windows: "stdin Bad file descriptor"

I didn't use `-optl-mwindows`. I guess the dependency on SDL is doing this.
Anyway, I was trying to print some debug messages to see what was going wrong.
Replaces the debugs message with on-screen messages using `SDL-ttf` package.

Thanks,
Thiago.
