Strange behaviour of created *.exe - eclipse

Has anyone any idea why the resulting exe from a build comes with a console?
I've built an EXE and it shows up with the window it should (the right one), and a console window (the left one - obviously).

This behaviour is the same for the debug - exe and the release - exe.
When I start it from Eclipse the console window does not show up.
(Eclipse Galileo / MinGW / C)

Find the linker settings, and add the -mwindows switch.

you might look into this here surely answers why Eclipse is not opening your console window
There seems to be no way to get a java.io.Console object when running an application through Eclipse. A command-line console window is not opened with the application, as it is run as a background process (background to Eclipse?). Currently, there is no Eclipse plugin to handle this issue, mainly due to the fact that java.io.Console is a final class.
All you can really do is test the returned Console object for null and proceed from there.
as far as your console window popping is concerned, you might be using System.console in the application
Hope this Helps

eclipse debug perl curses

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.

No Java console output in Eclipse; works with PyDev

I have both a Java and a PyDev project in one workspace. When I run the PyDev project (either the main script with Run > Run As > Python Run or its associated unit test with Python unit-test), the console output looks fine. However, when I switch to the Java project, open the main class, make sure the cursor focus is in the main class, and run it with Run > Run as > [my run config], no output shows up in the console, stdout or stderr. I've tried with Run/Debug > Console > Fixed width console checked and unchecked, similarly for Limit console output. "Allocate console" is check in [my run config].
I have tried redirecting output to a file in my run configuration, but the log file is empty after a run; thus, I suspect stdout/stderr are being trapped somewhere. I suspect that it is PyDev causing the issue because when I run the Java project, this exception reliably shows up about 6 times in the error log:
Launch shortcut 'org.python.pydev.debug.ui.launchShortcut.python.unittest' enablement expression caused exception. Shortcut was removed.
stacktrace:
org.eclipse.core.runtime.CoreException: No property tester contributes a property org.python.pydev.debug.ui.python_type to type class org.eclipse.ui.part.FileEditorInput

at org.eclipse.core.internal.expressions.CompositeExpression.evaluateAnd(CompositeExpression.java:53)
at org.eclipse.core.internal.expressions.AndExpression.evaluate(AndExpression.java:29)
(... and so on)
Additionally, printing from a Java program in a different workspace that only has Java projects works fine.
I tried uninstalling PyDev and restarting Eclipse, but I'm still having the same issue. I still have those errors after reinstalling PyDev, too.
Has anyone run into this issue before, or know of a way to fix it?
Well, I feel like an idiot; turns out, I had redirected stdout/err to a log file that I had long since forgotten about, and stuck somewhere difficult to find.
I ran into the same problem so I did some research. Seems like there was an old issue (2006-2008), but it was resolved by adding an option to the launch configurations to allocate a console. This is available from the Run -> Debug Configurations menu option, Common tab. Perhaps this is simply unchecked after the PyDev install?
If this is a new bug, there were two possible workarounds suggested:
Set up debug launch configuration that uses remote debugging instead of local debugging.
Use a buffered writer to System.out.

Ipython in pydev interactive debugging console(eclipse)

I have ipython working in pydev when using the normal interactive console, however when entering debug mode the console reverts to the standard pydev console. If I close this console and re-open it, ipython returns and I can use it as normal. Am I missing something, or is this a bug?
-Eric
Actually since PyDev version 3.0 you can attache a IPython console to a debug-session:
http://pydev.org/manual_adv_interactive_console.html#full-debug-support-in-interactive-console
To enable that feature, go to window > preferences > PyDev > Interactive Console and check 'Connect console to Debug Session?'.
Then only hassle is that you have to re-open a new IPython-console every time you re-launch the program in debug-mode.
Actually, Eclipse itself can have multiple consoles open at the same time... if you want, you can create multiple console views and pin a different console to each view (if you don't pin the console, one console will be shown on top of the other and you'll have to do the switching from one to the other manually).
As it is now, the debug console is not the same as the interactive console (it's a simpler version because of issues with the eclipse integration, although there are plans to be able to attach an interactive console to a debug session).
So, what you described is what should really happen (not really a bug).

Difference in Run & Debugg mode in Eclipse for Perl

I am using Eclipse along with EPIC plug in and pad walker for running my Perl project.
I am facing a strange issue
If I "Run" the project, the system fails and exits Perl without any error message.
But if I "Debug" the project and then give "Run" the same Perl scripts work fine as expected.
Could anyone let me know the difference in the two mode ("Direct Run" & "Debug & Run")?
Found it in the EPIC source code: EPIC adds the "-d" command line option for the debug target. It does some interesting things with the stdin/stdout too to remotely control the debugger. So maybe there's some side effect there? Can you share the error message?

Whats the shortcut to Debug in PyDev using Eclipse

The shortcut key is F11 to start debugging. But issue is that I have to be on that file and then hit F11 to start debugging.
Eg.
my file to launch the application is "launch.py" and "example.py".
example.py is open in the editor whereas launch.py is not.
Now, if I hit F11 it will try to launch the application using "example.py" and terminates due to error (as expected).
So then I have to open the "launch.py" in the editor and then hit F11 to start debugging the application.
Is there any neater way to configure the debugging, so that it starts the application in single hit/key?
Edit: example.py is some other file (some module). It does not launch the application.
As this PyDev Eclipse Tutorial suggests:
After the first run, if you type Ctrl+F11, the last file ran is re-run. Or, if you type just F11, a debug session is started with your last run. Let's test this...
Note: This behavior changed in Eclipse 3.3 -- but it's generally recommended to restore it in the preferences at: window > preferences > Run/Debug > Launching and set the Launch Operation to Always launch the previously launched application.
This tutorial will always consider this as the default option.
So, did you have this option selected?
If you have launch at least once launch.py, then you can re-launch it easily.
Although this isn't strictly an answer to what was asked initially, it might help someone looking here that had the same problem as me...
I'm a Java developer mainly, so have the Java view open almost all the time. However, sometimes I want to run some python file to test something (or just create a quick python script, and run it)...
In the Java editor, if the current class has a main(String[] args) method, I run it with (and popup the dialog to ask me what exactly I'd like to run in the middle)
alt+shift+x, j
Unfortunately, that doesn't work in the Python view, and I've not found a similar solution - it just asks me if I'd like to run it as a Java app... however, as the VonC says, you can run the last run thing (provided you've set the preferences accordingly) with
ctrl+f11
and this seems work well with python run configurations too.
But... What if the last thing I ran was a Java program, but I now want to run the active .py file? Previously, to run the .py file, I'd have to go digging through the buttons on the toolbar with the mouse, and I tend to prefer keyboard shortcuts...
Solution! So, finally I come to the actual useful bit of this answer - I just discovered by accident (typing Ivan's suggested shortcut, but missing!), it appears that
f9
will run the currently active python file.
Hope that helps someone get just that little bit faster...
I use CTRL+SHIFT+F9 to relaunch the previous debug configuration in Pydev.
