It's been days since I try to make my IDE (Code::Blocks version 13.12, I tried on 10.05 too) work. Any program (including a simple Hello World! program) I would make would show a black console showing nothing but an " _ ". I have made an exception in my antivirus (Avast!) for the file containing the IDE) but the same thing happens . I have tried re-installing twice, i have tried resetting the compiler and debugger's settings to default, auto-detecting toolchain executables ,but the same thing happens.
I have tried rebooting my computer several times, same thing happens.
I would like to know what I can do to solve this problem , because I don't want to get another complicated compiler (I am a beginner,) , as Code::Blocks fits my needs perfectly.
The following codes produces a blank console:
#include <iostream>
int main()
{
std::cout << "Hello world!\n";
return 0;
}
I had the same exact problem, with Eclipse, Visual Studio and then with Code::Blocks (I tested them all). I suggest you follow this video tutorial after you confirm the problem persists with a second IDE : https://www.youtube.com/watch?v=zOGU8fC3bvU&index=6&list=LLHcXdIeBMN4XYRZAk4IeXmg&spfreload=10 . It will take you step by step on how to install a given compiler.

I am a first time C++ user, and I have been working for 8 hours trying to build and compile the simple "Hello World" program with C++ in Visual Studio Code. I have CygWin64, but I'm not sure if it's connected to my VSCode. I have installed the extensions C/C++, C/C++ Compile Run, C++ Intellisense, Clang-Format, and Easy C++ projects.
So far I have tried
#include <iostream.h>
main()
{
cout<< "Hi there";
return 0;
}
and
#include <iostream.h>
int main() {
std::cout << "Hello Easy C++ project!" << std::endl;
}
Using iostream.h helped me to get to work (it wouldn't at first), but I'm not sure if that is helpful, since other posts say that .h is very archaic. I have also tried editing my c_cpp_properties.json file. Sadly, I still get the message:
"> Executing task: bash -c "make run" <
'bash' is not recognized as an internal or external command,
operable program or batch file.
The terminal process terminated with exit code: 1
Terminal will be reused by tasks, press any key to close it."
I am not sure if I need to install an alternative to Clang (I haven't found one), or run something initially on Cygwin64.
I have been looking online for suggestions and following pages such as https://dev.to/acharluk/developing-c-with-visual-studio-code-4pb9 and https://github.com/Microsoft/WSL/issues/1598, but I still can't seem to get around this problem.
Any help would be very appreciated.
Thanks,

I have this well known c++ program in my Visual Studio 2015 Prof:
#include <iostream>
int main(int argc, char* argv[]) {
std::cout << "Hello World!" << std::endl;
return 0;
}
As expected, it shows "Hello World!" if I hit Ctrl+F5. However, if I go to the directory within an cmd.exe and execute the HelloWorld.exe file, it doesn't show anything as output, but does quit (I can type in again).
According to a similar question I checked the settings of the project but I did not need to change anything, the Configuration Properties -> Linker -> System -> SubSystem already is at Console (/SUBSYSTEM:CONSOLE).
Flushing the std::cout also didn't help anything. It is reproducable on every freshly created project of VS2015 on my Win 7 64-bit machine and seems to be presistent after rebooting.
What is wrong with my IDE / settings?
After the hint of #Scheff I threw the exe file into "Dependency Walker". It gave me a missing UCRTBASED.DLL and lots of second and third level missing dlls (I think this is usually the case on every application?).
I somehow think my (recently installed) anti virus did interfere with that, because it shows some messages in the log regarding my HelloWorld.exe.
However, deinstalling anti virus and restarting machine did the trick. I can finally see Hello World! on cmd.exe.
I've recently started to learn C++ and I'm trying to compile and run a very simple program.
#include <iostream>
using namespace std;
int main() {
cout << "Hello World!" << endl;
cout << "Hello Again!";
return 0;
}
The program itself compiles as it should without any errors, however, when the program runs, it seems to stop after cout << "Hello World!" << endl;. I find this very strange, as my friend is sitting right beside me, doing the exact same thing and it works for him. The same thing happens when I try to use the sizeof();; it does not return any value, however, when my friend does this, it works.
When I ran it in NetBeans, it first generated the error
RUN FAILED (exit value 255, total time: 2s)
And another time I ran it, it generated the same error, but with a different exit value. Although it is now back to 255.
When running debugger in NetBeans it produces
SIGILL (Illegal instruction)
a few times before it stops working.
I have installed the MinGW compiler at the default directory (C:\MinGW), and this is the compiler that NetBeans and any other program is using. I have also added the path to the System Environment Variables at the end of the "Path" variable:
;C:\MinGW\bin;C:\MinGW\msys\1.0\bin
Trying to run and compile the same code in Atom results in
Hello World!Press any key to continue . . .
I have tried reinstalling the compiler, and restarted my computer. None of which seems to work. I've also tried \n, which works.
My question is, is there anything wrong with my compiler or computer, or am I missing something obvious? And is it possible to fix this?
(Sorry if this is a duplicate, I've searched for a few hours, not able to find anything useful)
I found the culprit!
In my System Environment Variables, C:\MingGW\bin and C:\MingGW\MSYS\1.0\bin was at the bottom of the list. This meant that it was below C:\Program Files (x86)\GNU\GnuPG\pub (Which I think, if I'm not mistaken is another compiler).
Although all paths in NetBeans were correct, it seems like the system didn't like it when another compiler was listed above MinGW.
I solved the problem by moving the paths for MinGW up, above the GNU.
I'm getting started with C++ and I use Qt Creator (I run Lubuntu 13.04).
Today, as any good start with programming, I wrote my Hello World program to see if things work after installing Qt5 and Qt Creator.
I created a new Console Application project and wrote:
#include <iostream>
using namespace std;
int main()
{
cout<<"Hello World!";
return 0;
}
Saved my project as Test, and tried to run it.
I just keep getting
Starting /home/MYUSERNAME/Qt Programming/Test/Test...
Cannot change to working directory '/home/MYUSERNAME/Qt Programming/Test': No such file or directory
/home/MYUSERNAME/Qt Programming/Test/Test exited with code -1
Any ideas on how to fix this?
Thanks in advance.
Just maybe problem is a space in 'MYUSERNAME/Qt Programming/Test'.
Anyway take a look in project build settings. Something is wrong with path where compiler is looking for your project
Are you sure there is a "Test" directory in the "/home/MYUSERNAME/Qt Programming/Test" directory ?
Using my qt4 installation I've tried starting a new Qt Console Application, chosen the folder to create project in, typed out Test for the Project name hit next, deselected Debug, but kept release. Hit next. chose none for version control, hit finish.
Program skeleton shows up. Must delete the include statement for QCoreApplication. Replace it with iostream. Deleted "QCoreapplication a" and "return a.exec". put in std::cout<<"Hello World \n"; and return 0;. Then I saved everything hit the play button and xterm is opened and displays hello world. No problems here. I even tried with spaces in directory names. Again no problems.
Then I tried creating project non-qt-project->plain c++ project. After the same menus as above, found a skeleton with exactly your code except with an endl at the end of cout statement. Hit the play button. Again no problems here. Again it opened up xterm and printed out Hello World!
Don't know what else to tell you. If you changed the name to Test AFTER you created the project, I would say, start again and this time don't change the name.
I may install qt5 on my opensuse 12.3 x86_64 installation and will be able to see if there are problems with it.
I just installed c/c++ development tools for my eclipse and everything is working except no text is being printed in the console when I run the hello world program, but I receive no errors. I'm really stumped, anyone know why this is?
Edit:
Ok I realized if that debug it, it works correctly, but not if I run it, any ideas there?
Are you using a 64-bit version of Eclipse? If so, that might be your problem. The 64-bit version doesn't do console output. sigh Try downgrading to the 32-bit version.
On SO, check this question.
On the Eclipse forums, check this thread.
Does a window pop up then disappear? It could be printing it in console then closing as soon as it hits the end of the code...
try to make your code like this:
#include <iostream>
#include <conio.h>
using namespase std;
int main()
{
cout << "helllo, world" << endl;
getch();
return 0;
}
You must set the environment so the eclipse can find the c++ compiler.
Go to Computer and right click Properties -> advanced system settings -> enviroment variables.
Scroll down in system variables and find the path (it is named so). Press edit and append in the path the value C:\MinGW\bin;C:\MinGW\msys\1.0\bin;. You will have something like C:\MinGW\bin;C:\MinGW\msys\1.0\bin;C:\programfiles........
Then start again the eclipse the problem should have been solved.
