How to run .exe immedeatly after build in Eclipse CDT [duplicate] - c++

I'm trying to conveniently have the updated code in effect when I click the run button in Eclipse. At present it will run the last build and I have to manually click build before clicking run to see the changes.
Can someone advise me on how to configure Eclipse to autobuild the current project (if changes has been made) before running the code?

There are multiple settings for auto building. The one you could be missing is the setting under Launching.
Two other settings are here:
And the last setting is the one you likely already know about:

If you want to automatically build your project on save (or before run, if needed), then from tool-bar menu go to
Project -> Properties -> C/C++ Build -> Select Behaviour Tab on the right panel, -> tick the "Build on resource save(Auto build)" , finally hit OK
That is it...

How do I run multiple program in codelite

I had to do my homework with c programming in codelite. Just like codeBlock and Dev-C++ which give user to run multiple console program in the same folder, however, when I run it on codelite it fail.
I have create different workspace folder or even different project.But when I try to build it, only the first c file get to build but not later created c file.
May anyone please help me on this issues?I just want to rum multiple program in codelite just like code block.
Hitting F7, builds the active project (the project with a bold text in the workspace tree view).
To change the active project:
Double click a project, or:
Right click a project and select Make active
To build all the projects in a single click (Default key: F7):
Add new project to the workspace
Right click it and select Build Order
In the dialog that pops up, click on the checkbox near each project
Build the dummy project (make it active as described above) and hit F7
OR, build the entire workspace (Ctrl-Shift-B):
From the menu bar select Build -> Build Workspace (default key bindings: Ctrl-Shift-B)
To execute a project (default key binding: Ctrl-F5):
Make the project active by double clicking it
Hit Ctrl-F5
NOTE:
All keybindings can be changed from Settings -> Keyboard shortcuts

How do I delete the launch configuration of a deleted project if Eclipse(C++) refuses to automatically do it?

This all started when Eclipse stopped automatically creating the executable after debugging/compiling the program.
Click in top menu on Run -> Run Configurations.... There all configurations should be listed and you can remove them. You can also check Debug Configurations....

Eclipse: Nothing to build for file

I did look up on the Internet to find the solution for my problems, unfortunately all advices didn't seem to help so perhaps you will be more helpful in my case.
I did set up my Eclipse IDE with MinGW,
I did set up my Windows' environment variables right, for example:
added C:\Program Files\eclipse; C:\MinGW\bin;C:\MinGW\msys\1.0\bin
and somehow managed to create project with .cpp file that actually worked, at the beggining I build this file and than run it with these simple icons. Somehow, it compiled without errors and output the right results.
I hoped that it would remain perfect for eternity, but somehow today while dealing with new c++ project I have encountered the following problems.
I build new C++ project, by clicking:
File -> New -> C++ Project -> marking executable project Hello World Project -> by default I set up to use MinGW toolchain (nothing has changed since the moment it worked perfectly smooth) -> name project and start work.
Building project looks ok, I get no errors whatsover. But when I try to run it the console window is completely blank - with popping info: Nothing to build for [project name].
I really hope that once I've made some project actually work all changes will remain untouched and that I will not have to fiddle around once again with all these settings.
I did not change anything at all and now it doesn't work...
Right click on project -> Properties -> C/C++ Build -> Environment -> all variables are set.
Toolchain set to MinGW which has worked so well.
And yet I can't run this executable program, this IDE is really starting to drive me crazy.
Any idea what might have happened over the last magical six hours when suddenly Eclipse refuse to work properly again ?
Try to right click the eclipse project and click refresh. An item should appear under executables. If an item appears you should be able to run it from inside eclipse (not sure how though, maybe by double clicking or from the right click menu) or by using the command promt. To run it through the command prompt, using cd command browse to the folder where the executable file resides (somewhere inside the project folder inside your workspace folder) and run it by typing the name of the executable (fx hello.exe or just hello).

How to enable Eclipse to autobuild/autosave changes before run (CDT)

I'm trying to conveniently have the updated code in effect when I click the run button in Eclipse. At present it will run the last build and I have to manually click build before clicking run to see the changes.

The program file specified in the launch configuration does not exist

I am facing some problems regarding eclipse for c/c++. I am trying to create a new project, I provide the code, and after running the code I get this error:
The program file specified in the launch configuration does not exist
C:\Users\elisabeth\workspace\mm\Debug\mm.exe not found
Please notice that I am working with spice toolkit; I set the path for the "include" files and the libraries, but still I can not have a result.
What causes this error and how can I resolve it?
Right click on your project --> Properties
Run/Debug settings
Delete whatever is set as "launch configuration for '........'
Project --> Clean
Project --> Build Project
You can create a run configuration. Go to Run > Run Configurations. Click New button, fill C/C++ Application field, i.e., insert path to your executable. The new configuration will appear in the list which appears when you click to the arrow next to run button.
Of course this assumes your can build without problems, otherwise you won't see an executable to point to.
You can clean the project, build it again and run it as a local C/C++ application. Simplified steps as follows,
Right click on the project
Clean Project
Again Right click on the project
Build Project
Again Right click on the project
Run As ->
Local C/C++ Application
As the error reads:
C:\Users\elisabeth\workspace\mm\Debug\mm.exe not found
First of all you need to check whether there is an executable "mm.exe" in your Debug folder. (Of course, it is not there and that is why the error)
Go to Project > Clean
and you should see some files being deleted from your Debug folder
Go to Project > Build Project
and you should see some new files being generated e.g. mm.d, mm.o, mm. This "mm" is probably the executable you're looking for
Now that you know what your executable is, you should tell eclipse what file to execute instead of mm.exe. Go to Project properties and in run debug settings create a new configuration (or edit an existing configuration, if there is one already). In this configuration, in main tab, in C/C++ Application specify a full path to "mm". Which, in your case is - "C:\Users\elisabeth\workspace\mm\Debug\mm"
A better way to do this in eclipse is:
${project_loc}/"your folder"/"your executable file"
e.g.${project_loc}/Debug/mm
what worked for me is file->refresh
then do the Debug configuration again by choosing the right c/c++ binary again.
Avoid troubles with configuration by going into Project properties > C/C++ build > Refresh Policy and specify your project folder. The configuration option "Search project" will show a correct folder then and you will see whatever you build there - Debug, Release or both. You don't want to specify the folder using Browse option every time you import project or switch configurations.
As this is the first SO discussion that appears for this topic on Google and none of the answers solved the problem my students were having, I would like to mention the solution we eventually found from this answer:
Open project properties (Right click on your project, choose Properties on the menu)
C/C++ Build -> Settings
Click on Binary Parsers tab and check PE Windows Parser
Keep clicking Move Up until it is at the top
This had been set to Elf, even though we were using a freshly downloaded Windows version of Eclipse.
sometime missed closing curly brace can be part of a problem. Make sure prototype your function at the beginning of the file. Then right click your project in the left side bar. click clean project. then click build project and finally run project
I encountered similar issues and their related problems a few days ago. Finally, I found out that, just because I had moved my project folder (workspace folder of Eclipse) to another place so Eclipse could not find what its need as usual.
Solution: I just set the workspace to my new place (Hey Eclipse, my workspace now is here) :
Menu "File" -> "Switch workspace" -> "Other..." -> click "Browse..." button and point to new place then click "Select Folder" button and click "Launch" button.
Nice day.
