I'm a beginner in C++ and I started an Udemy course. In that course they recommend using CodeLite as IDE, so I decided to give it a try. In the course, they write a basic program that displays "Hello world!" to show how the IDE works. They compile then execute it, and a terminal window opens with the "Hello world!" message like normal.
In my case, after following the setup process step by step and using the exact same code as them, when I compile and execute the code, my terminal flashes for a split second and then disappears. In their video the terminal remains open but I thought that since they have an older version of CodeLite maybe in the newer one that I have, the terminal is supposed to close by default.
I went online and found people saying that a way of keeping the terminal open is by adding #include and system("pause"); on Windows, but in my case the terminal keeps behaving the same, and CodeLite doesn't report any problems. I've also tried cin.get(); with no success.
Any idea what could be causing this problem?
I had the same problem and I did these steps to solve the problem:
Uninstalled CodeLite.
Installed MinGW correctly.
Then reinstalled CodeLite.
Then did tutorial steps: Click Scan then select MinGW.
After I did these steps, it worked normally.
I had the same problem running Codelite on OpenSuse Leap 15.1. I eventually found a very simple answer. Go to the Settings menu, select Preferences and then Terminal, on the left towards the bottom. Change it to konsole to use the standard terminal, rather than the codelite-terminal.
I know this is an old question, but did not see the answer that worked for me. Debugging (F5) will close the terminal after completion.
However, running/executing (CTRL+F5) will not. Leaves terminal open. At least this is the case for me, and hopefully this helps someone out.
I know this is an old question, but CodeLite has a Project-level setting for "pause when execution ends" which will pause the program before the terminal closes so that you can see outputs and the like.
To turn on just right click on your project, go to settings, and it should be in the center of the general tab.
I went online and found people saying that a way of keeping the terminal open is by adding #include and system("pause");
And this is the wrong way to do it - the desire to leave the window open/closed is not meant to be controlled by your program; but the thing calling it. For example, you break the ability to run it as part of a headless script.
Much better would be to run it in debug and put a break point at the return of main, or to find the configuration option in your IDE that stops it closing the window.
I am not aware why CodeLite would behave like that. If you really added some pause or blocking call and it still closes, it looks like it is not really running the program (e.g. something breaks before that or something is misconfigured).
First, try to open a terminal yourself (e.g. cmd or PowerShell on Windows), and execute your compiled program there -- that way, the terminal will remain open. If that works, then compilation went fine, but something is wrong with CodeLite's configuration, most likely.
Otherwise, as a last resort, since using CodeLite is not strictly required, simply switch to another IDE/toolchain, e.g. Visual Studio (on Windows).
For some reason, after closing and reopening CodeLite, it now works, the terminal remains open when I run it from the IDE. I don't know what solved the problem since I've closed and reopened CodeLite at least 5 times before this without anything happening. Thanks for the help though.
I had the same issue. What I found wrong was that the compiler that I installed was 32bit and I was using the 64bit CodeLite version . Try Installing the 32bit CodeLite version and it should work fine.
It worked for me.
I had this problem also, I tried uninstalling and reinstalling code lite but the problem still occurred.
I went back and checked the Environment Variables in control panel and I had placed the systems variables in "Path" to the incorrect Bin directory.
I corrected the entry, uninstalled and reinstalled code lite again and the problem was resolved.
Hey I also had the same problem, doing the same course! What I did was to relocate my mingw-w64 folder, deleted the earlier path from environment variables and added the new path. I uninstalled CodeLite; not saving the user information. I actually downloaded the 14.0.0(64-bit) instead of the newer version 14.0.1(64 bit) . Then I did the steps that Frank tells you and it worked out for me.
I am completing the same Udemy course and encountered a similar problem of the console closing immediately. I encountered the problem for a workspace with 1.) a long name and 2.) ending with an underscore "_". I reduced the size of the folder name which also involved deleting the trailing underscore. This appears to have solved the problem. I encountered this problem with one of Frank's provided workspaces so I knew it was not a compiler issue.
I had an issue with section 20 of my Udemy course because it had parenthesis in the workspace folder name. "(STL)" at the end. Once I got rid of the special characters, it worked fine.
If pause("system"); or cin or restarting Program and whole PC solutions are not working, then make sure to:
Copy your code.
Create new Project and past your code there.
Make sure the new project is selected before trying to double-click it.
Notes:
You can now delete the old not working project and rename your new project.
I don't know what's the reason of the problem, but I did that and it worked for me.
You need to make sure if it is 64bits CodeLite then you have installed 64bits MinGW. Through the IDE itself, you can re-run the setup wizard
Restarting Codelite worked for me ...
I'm using Eclipse Helios in Windows7 for C/C++ programming. I wrote a basic C++ code and tried to compile. The output is:
**** Incremental Build of configuration Release for project Programming Project **** Info: Internal Builder is used for build g++
-o "Programming Project.exe" "src\ch_3_excercises.o" c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe:
cannot open output file Programming Project.exe: Permission denied
collect2: ld returned 1 exit status
How can I fix this error?
All you have to do is go to project on the menu bar and then click clean project. Clean all of your projects and then it should work.
The same problem with me while editing my code.the easy way i used is ::::::::
press the red button(Terminate) before editing your code then run your code
it is tested and works
I know this is an old question, but it probably does that because you are interrupting the flow of your program, for instance using scanf(), and not actually giving the input it requires, so when you use the command Build the project, then eclipse is waiting a stream from your keyboard (for instance, maybe it's a different type of program, but follow me here).
Once you know than that is the problem, then you might wanna keep an eye in what is that you are not giving to the project and that it is expecting you to; and the way to stop this annoying error the next time you get it, is that in your console view you press the red button.
That will happen if the program is still running in another window. The .exe file stays open until the program finishes execution, and you can't delete a file while any processes have it open.
I don't use Eclipse for C/C++ development, and the problem almost can't happen with Code::Blocks, but this happens very often with Visual C++. Just close the other window and rebuild.
Check your quarantine folder of your antivirus. If you see the executable file, then add it to the Trust list or White list. Your problem should be solved.
It means the same .exe file is running in your system.
A program cannot be build when its already running.
So the simple and most obvious thing to do is:-
Open task manager
Find <yourfilename.exe> under processes
Right click and end task
This stops it from running in background.
So you can build your program anew and run.
I do use to work in Eclipse cause i find it pretty good, but every day i am encountering this problem..."'Cleaning all projects has encountered a problem'. Errors occured during the build." when I hit the "clean projects" button. I have win 7 64 bit.
The only solution for this issue to work is to restart my computer. But I don't find it that good, because even if I restart my computer in the next 5 minutes when I compile a certain program it gets stuck again, it shows the same annoying message.
Please give me a solution to make this work. I wouldn't like to switch to visual studio...
It's hard to tell for sure, but your application might have some unreleased resources which 'clean' command can't remove. Did executable process terminate? If not, you whould have this error. You could try to remove binaries from build folder manually and see what file causes and error.
I'm having a problem in visual c++ 2010 express, when I try to run my code it runs well, but when I close it, it runs again. So I think the problem was in my code, so I try a very basic code like this.
#include <iostream>
int main()
{
std::cout << "test" << std::endl;
return 0;
}
then I try to reset the vc++ settings, but still the .exe is runnning 2x even in the debugger. Then I try to reinstall but still the same problem. I try to import my .exe to other machine to see if it will run 2x, and yes, it runs again after I close it. So I hope someone here can help me fix this problem.
It's weird but it's possible.
There is someone who asked before on how to do it: Run multiple instances with one click in Visual Studio (what you are get rid of is sometimes what others desire to have :)). The following notes are borrowed from there. So you can check your visual studio setting whether the followings are set or not. Probably you got the following set. Hope it helps.
suppose your current project is A, and it's output is c:\bin\my.exe
add an empty project to the solution for A, call it 'Dummy'
under Dummy's Project Properties->Debugging set the Command to point c:\bin\my.exe
under Solution Properties->Configuration Manager, uncheck all builds of the Dummy project so VS won't try to build it (building an empty project fails)
under Solution Properties->Startup Project, select Multiple Startup Projects and set the Action for both A and Dummy to Start
now hit F5 and your exe will be launched twice, each under a seperate debugging instance. (as you will be able to see in the Debug->View->Processes window)
I have downloaded the latest Eclipse CDT release (Helios) and wanted to try my luck with some C++ programming (haven't done that in ages).
I tried to do the "Hello World" project, but I got stuck quite fast.
First thing - the #include <stdio.h> and #include <stdlib.h> got marked with an 'Unresolved Symbol' warning. So I found the place where I can add include paths and pointed it to these headers from the Visual Studio installation I have.
After that, it looked fine but:
I don't see compilation errors/warnings in the Problems tab.
I cannot run the code - I get 'Launch failed. Binary not found' error
My question is simple - what are the steps I really need to do to get my code compiled, linked and executed?
I tried looking for it on Eclipse's site, but didn't find any reference to that.
I'm making a guess here, that your are running on Windows, because that particular error seems to be a windows related one.
You seem to be missing the basic toolchain needed by the CDT to actually build the project. You need some files Before You Get Started. I suggest the mingw installer, as it is simple, and lets you actually build Windows compatible binaries.
Check out the link above, and then make sure your project links to the toolchain. Hope that helps.
A starting point could be:
File -> New -> c++ project
Type a name for the project, select Hello World c++ Project under Project Type and click Finish.
Right click on the project -> Run As -> Local C++ application (or just click the Run button on the toolbar).
I was getting the same error until I ran the "Build All" command. That command created two new folders, Debug and Release. Then when I clicked the "Debug" button, it asked me which one I wanted to run and I selected "Debug" and it ran perfectly.
It seems like the binary it couldn't find was created from the "Build All" command.
