I have a c++ program that uses libVLC and QT. When the program starts it creates the QT UI but it also opens a command prompt that holds any VLC errors. Does anyone know a way to suppress to CMD window?
Don't use "--extraintf=logger" as command to libvlc.

I would like to use heob to check my app for memory leaks. This is what i tried: I opened the project "analogclock" from the examples collection in qtcreator. After that i have chosen "Analyze" and "Heob" from the drop down menu. After choosing the heob path and a click on the ok button, the application starts and a console window "heob32" is displayed. But now nothing happens. Just the word "kill" is displayed in the console window. I can´t see any output and if i close the analogclock app i get the message: "heob: cannot create target process". Can anyone help me further to get useful output from heob?
What OS are you using and what heob did you install?
You need to download and install heob separately from Creator. Creator just installs a link without heob itself. Have you done this? Are you really running on a 32-bit system (there is a heob64 in case you are using a modern OS).
Did you configure your heob installation in Qt Creator correctly?
Can you run heob from the commandline with reasonable behaviour?
I am trying to get qt set up on my computer to make a gui for a c++ program. I installed it with no issues but it will not open. I open qt community an it opens a plugin loader and closes. Watching it from task manager it has multiple cmd sub processes open, a clangbackend.exe then a windows problem reporting processes starts and everything closes. I've tried rebooting and reinstalling. I'm on windows.
Original Thread
Try running this command in cmd.exe (command prompt):
c:\pathto\qtcreator -noload Welcome -noload QmlDesigner -noload QmlProfiler
ps: replace pathto with the path to the qt creator bin. ex = if your path to qt creator bin is, C://Program Files/Qt/Tools/QtCreator/bin, so the command looks like,
c:\Program Files\Qt\Tools\QtCreator\bin\qtcreator -noload Welcome -noload QmlDesigner -noload QmlProfiler
If this opens Qt Creator, go to help menu->About Plugins and disable "Welcome" permanantly.
If the solution above doesn't work try disabling your antivirus software like McAffee.
I have create a wxwidgets program(Pure C++) , the build is success and running is OK
But when I click the program in finder, a terminal windows is popup.
How to avoid the terminal window being popup?
PS: Similiar problem is also seen in Visual Studio, and can be fixed by changing subsystem from Console to Windows
Is there a similiar configuration in Xcode?
You must make a bundle for your application under OS X. If you use Xcode, this should already be the case. If you use makefiles/command line, look at how the minimal sample included in wxWidgets distribution does it.
When I compile a C++ console application in a Linux IDE like Qt Creator or code::blocks, the terminal window (unlike Windows Console) waits for pressing Enter to be closed. Codes like exit(0) and system("exit") don't work.
Is there any code or option in Qt IDE to let the terminal window (xterm or konsole) be closed automatically after execution.
It is actually made for you. If you build executable of your application and run it from terminal (outside of IDE), it (your application... not the terminal) will close after execution (return in main).
CodeBlocks uses smth called cb_console_runner to run executables and wait for ENTER to close terminal. I am not sure how is it possible to make it work without cb_console_runner
EDIT: In codeBlocks... remove/rename cb_console_runner in /bin and it is solved:)
to make it easier: run this command:
sudo mv /bin/cb_console_runner cb_console_runner_s
In QtCreator in Project->Run settings
uncheck "Run in Terminal"
I am trying to make an application using QT for C++ using codeblocks. Every time I run the application a command prompt window pops out followed by the gui for my application.
How do I suppress the command prompt window?
Here the possible answer
Just remove
CONFIG += CONSOLE
from your .pro file
Yet another option for Code::Blocks. In IDE menu
Project->Properties->Build Targets: change Type from "Console Application" to "GUI Application".
