I am writing a small FLTK (GUI) program on windows 7 using Eclipse Kepler. My "int main()" function is not even set to receive any command line arguments, yet every time I build the program exe and run it a command line pops up being the GUI interface.
Does anyone know how to suppress this? I do not need a console display for any input or output etc. as this is all controlled via the GUI interface.
Thanks.
It has nothing to see with eclipse. It's a standard behaviour of c++ applications on Windows. Look for console on this page. You will find how to disable it.

I am writing a Perl program that uses curses for output and move the cursor, and color characters. Previously, when I was working under windows I use Komodo it was able to run an external console.
Now I work in Linux environment and use eclipse + epic. If you try to just run the script, it uses the internal console eclipse, which is very cut. You can just run the script using external tool, but I'm interested to debug using external console window. Is this possible?
Unfortunately, use of a File and /dev/pty/1 does not help in solving my problem.
The fact is that in this case it is impossible to get the characters introduced in the console through curses getch(). Always returned 1 instead code of pressed key.
Here is an answer that will take you most of the way (based on post #6 of: http://ubuntuforums.org/showthread.php?t=743131, although since then, in the "Indigo" and "Juno" versions of Eclipse, things have changed somewhat, and this answer is up to date):
Go to "Run -> Debug configurations". Click on the (fourth) "Common" tab. Go to the third frame from top, and there, check-mark the checkbox which says: "File". Enter the file name of the console window you want your output in.
I downloaded and configured eclipse cdt along with MinGW and able to compile c programs.
My question, how to start executing the program in command prompt when Run option clicked from eclipse. Currently it always executes the program in eclipse console.
Reason to have command prompt for executing c programs is to accept user inputs.
I would also like to know is there a way to accept user inputs when c program running in eclipse console.
Thanks in advance,

I guess i am quite late but still you can try this out. You can execute c programs through Eclipse cdt by writing a batch file and calling them through a click of button or any other event handler. Just make sure you are in the correct directory before attempting to compile and execute the file.
You can find various resources online to create a batch file which can help you execute programs through the console.
On compiling the file, (if you haven't specified an output file), a.exe file will be created. To execute this file with command line inputs just type the following in cmd (as long as you are in the same directory)
a.exe "command line inputs"
where "command line inputs" are the inputs you want to provide to your program.
Hope this is helpful!
i know 8 years is very late,but maybe somone else like me see this,so my answer is :
you should use:
setvbuf(stdout, NULL, _IONBF, 0);
setvbuf(stderr, NULL, _IONBF, 0);
after every printf statment to be able to input data in eclipse ide console tab ,
as i understood :""The root cause of the I/O problem is that we're using Windows pipes to communicate with the underlying process. The pipes are buffered"

I'm making an eclipse plugin where I want to run a system command, and have the output of the command go to the eclipse console. I know how to do this via http://wiki.eclipse.org/FAQ_How_do_I_write_to_the_console_from_a_plug-in%3F
The problem I don't know how to solve, is to allow interactive input from the console for this command.
In essence, I want to kick off a command which runs in the console. The user can interact with this command (via stdin). I then want my plugin code to get a callback when the command has finished (or user has manually stopped/terminated the command in the console). Getting the return code of the completed program would be nice as well.
For simplicity sake, lets use the unix 'passwd' command as the example (this is the first common cmd I could think of that both has output and prompts for input). I don't need to hide the stdin however.
For reference, the command I'm trying to call is the CakePHP bake shell.
I assume that you got yourself a MessageConsole, like in the FAQ. Then it should be possible to use messageConsole.getInputStream().read() in a loop to get your input (but I have not tested this). See also the documentation of the IOConsoleInputStream for more options.
On the other hand I'm not sure why you are creating your own plugin to do that. The standard console implementation in Eclipse does exactly what you want. You can see that by running a small Java application, where you can use that console for input and output as well.
I'm currently writing some ncurses code and the native Eclipse (3.2.2) console can't display its graphics. I'd instead like to run the program through xterm. What I want is to be able to start xterm and run from there. I'd prefer to not get involved with any plugins or that jazz. Just something simple.
EDIT
So I have the answer and it was pretty simple...
Run -> External Tools -> External Tools -> New Launch Config...
Then select location of your terminal emulator. /usr/bin/gnome-terminal in my case.
after that set the appropriate arguments. "-e ~/ncurses/start" in my case.
Then make sure you aren't allocating a console by unchecking that option in the "Common" tab.
Annon add to his question:
its a pain to keep switching back and forth from eclipse and the terminal. I'm looking for a way to just hit something like"F5" and have it run my ncurses program in a new xterm terminal process
The simplest way to do that is to report the command line into an external tool configuration, and point eclipse to use a shell (like described in this program)
In the argument, you will add the command line eclipse execute (command line which can be retrieved as mentioned in the second part of this answer below).
Of course, replace 'cmd.exe' by the shell of your choice, and try not setting the 'Allocate Console' checkbox in the Common tab of that external launcher.
To launch through a xterm, without eclipse involved (not what you are asking for, just keep here for archive)
You can launch your program through Eclipse (Run Configurations), and observe through a 'ps' command the exact Java command line used.
Or launch it in debug mode, and right click the task in Debug view and open Properties. It will show the command line, as documented here.
Then launch that command line directly in your console (Eclipse being not involved at all at this point).
I'm using Eclipse on Windows, with the PyDev plugin for Python development. When I use 'Run' to start my application, it spawns a new Python (CPython) instance. When I use the 'terminate' button (red square), it kills the process. However, it appears to do a SIGKILL, so my shutdown handler is unable to clean up.
Is there any way to get Eclipse to send a SIGTERM, or simulate a keyboard interrupt (ctrl-c) from the Eclipse console?
Note: I'm aware there are other Python IDEs like Komodo or Wing that might solve this problem, but I'm not looking to switch over this.
Eclipse uses the Java Process API which sends the signal. This is a native API and there is no way to change that. I assume that you've tried to install a handler for SIGKILL, too, and that didn't work.
Therefore, the only solution would be to write a small batch file which lists the processes and sends SIGTERM to one of them. Invoke that from a command prompt. If you use Alt-Tab to switch to it, it's almost as comfortable as doing it from inside Eclipse.
Or write a plugin to invoke batch files.
I looked at How can a Java program get its own process ID? and came up with this.
System.out.println("kill -SIGINT "+ProcessHandle.current().pid());
I realize this isn't ideal if you don't want it printing this out for production but if you're just prototyping it's handy. Or you could put it inside an if that only runs if you're debugging.
