I'm trying to build and run my C++ program in eclipse but it won't work. My program doesn't have a main function, but it does have WinMain and includes < windows.h >. I compile it into an executable and everything works fine, but when I click "run" nothing happens. When I drag the executable to my desktop and double click it it runs no problem. But I would like to be able to run it directly from eclipse.
I've done some research and already tried the following:
I made sure "PE Windows Parser" is checked in "Binary Parsers."
I made sure the working directory is where the executable is (workspace/projectname/Release).
I made sure MinGW is in the PATH (I couldn't find msys, but everything is compiling fine so I don't think this is the problem).
Any thoughts?
1.- Go to Menu Run -> Run Configurations
2.- Double click over C/C++ Application in the left subwindow.
3.- At right subwindow, press button Search_Project and check your binary executable.
4.- Press Run.
If you need to pass arguments to your program, go to Arguments tab.
For next runs, you can use the PLAY toolbar button or use CTRL+F11.
Change your compiler to Visual C++ instead of MinGW GCC. Just copy your code to separate files. Then, you simply create a new project using Visual C++ as your tool-chain. Then you simple paste the files into the directory, and then run it.

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).
I try to program some stuff in c++ with eclipse, but I have slight difficulties.
When I create a new Project compiling and making works fine but when I try to run the Application I get the following error message:
"Launch failed. Binary not found"
So what I found out by using google is this workaround:
-right-click on the projekt in the projekt explorer
-select "run as" and then "run configurations"
-expand "c/c++ application" in the navbar on the left
-and in the main tab of the project select "browse"
-navigate to folder "debug" and select the .exe
after I do that, running works fine but I have to do it again every time I create a new Project, is there a way to automate this process?
And what I also noticed: I don't have a "binaries" folder in my projects in the project explorer, maybe its related to that, but I really don't know.
Any help is appreciated
Thanks

There will only be a Binaries folder if the build was successful. You will have to manually build to get a binary in order for the Binaries folder to appear. Likewise, if you clean (remove) your build folder then Binaries will disappear.
I would guess that Eclipse cannot find your binary "out-of-the-box" because you are using external tools to manage the build process; that is, if you have a custom makefile project (or another type of project that uses another tool to handle the building) then Eclipse will not be able to provide a default run configuration because it does not "know" where the binary is or even which binary to run if there are multiple. Thus, you have to set up the Run Configuration as you are doing now.
If you create a project and let Eclipse do the building, then Eclipse can find the binaries automatically. For example, simply create an "Empty C++ Project" under "Executable". Write some hello world code. Click build. Then click run. Eclipse launches the binary because it is managing the build process and thus "knows about" where the binary ends up.
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
as seen here stackoverflow.com/questions/9407430, answer number 3 or 4
In my case
I just save the programme. Press CTRL+B to build it.
Refresh it.
Then run the programme.
Now you can see this will work fine.
I have already answered this for other question see the link Launch Failed Binary not found Eclipse for C in Windows at 10th number.
I am trying to write, compile and execute a "HelloWorld" C++ program using Eclipse. I have managed to install and run Eclipse, create a new project and write the HelloWorld program. Now I would like to compile it and to run.
I did not find "Compile" option in Eclipse, but I found "Build Project" option in the "Project" menu. I assume that Build is what I call "compilation". After I clicked this options, Eclipse generated "Debug" folder, containing "src" sub-folder as well as 3 files: "sources.mk", "objects.mk" and "makefile". First, I do not know what these files mean (and which of them is my "executable"). Second, I still need to execute my program. I tried to click "Run" option in the "Run" menu. As a result I got an error message: "Launch failed. Binary not found".
Can anybody, please, help me to compile and run my code using Eclipse.
Eclipse being an IDE is meant to create projects not restricted to just one file as a result multiple files exists which have to be linked and compiled so as to work in sync as per the methods implemented in the project.To run the project or a particular program a binary of that particular project is required which gets created only if the build is successful .So a successful build is must for binary creation which in turn is responsible for running the project or program.
So first build the project using Ctrl+B after succesfull build then run the project.
This simple question was asked nine years ago, so I don't know if it is still active. Anyway, one thing not mentioned in the responses so far that might be helpful to others is that Eclipse requires a "Run Configuration" to run programs. From the original post, if the "Build Project" command returned successfully, then the "Debug" folder should also contain a file called "HelloWorld" at the same folder level as "makefile" and "objects.mk". That is your executable. To run it, go to Run -> Run Configurations, which should produce a popup containing a field called "C/C++ Application". Click the "Browse" button, find, and select the "HelloWorld" executable in the "Debug" folder. Click "Run" in the lower right and you should see your output.
I've got a makefile based project set up that builds my code on multiple platforms. On my Mac I want to use Xcode for debugging though. I've set up an Xcode as an External Build Project I can run the application from within Xcode. The output is shown in Xcode and if the app crashes it drops in to the debugger, but when running the debugger cannot locate the source files, so I just see assembly output. How can I tell Xcode where to locate the source?
I also cannot set breakpoints, but I think that this is all the same problem.
I was able to fix the issue of not stopping at breakpoints by setting a custom working directory for the executable.
Before this change I was able to build successfully using the external scons system from Xcode 4. My code would run when called from XCode but breakpoints would be ignored.
Then in XCode,
Go to Product -> Edit Scheme...
CHeck 'use custom working directory'
and I set this to the same directory as the executable.
Breakpoints then started working.
Ensure -g is included in the compiler options in the makefile.
Set a custom working directory in the scheme, set the executable if this hasn't already been set.
Ensure that the project isn't pulling in dylibs that haven't been compiled with -g. You might need a build step to run make install if the project builds dylibs as well as the main target.
Make sure that "strip" isn't being called. There are environment vars that xcode set that allow you to keep a working makefile when used outside xcode.
Just had this problem and this worked (Xcode 4.6) (got source debugging and working breakpoints)
In "Project Navigator" (the file-folder icon just below the "Run" button), right click and select "Add Files To your-project". Browse to the top level folder where you would normally run the external build, and click Add.
I'm programming with Galileo on Ubuntu.
My project is compiled through the terminal fine. But for the nice features of eclipse I decided to use eclipse. So I copied and pasted everything inside an eclipse project directory. Then I refreshed the project in the project explorer and everything was found by eclipse. (EDITED) But a red mark (the error mark) is shown on the project icon and when I build the project no binary file is created.
And the last thing is that all the files inside the project have no errors!
what's the problem?
Presumably it is a makefile project. Have you set up the Eclipse IDE to use make with the correct make arguments?
Have you set up the path for the include and lib directories that you need?
Right click on the project in the tree viewer and bring up the preferences dialog and make sure.
There is a console output tab on the Eclipse IDE. What does that say?
There is also a Problems tab that sorts the compiler output. What is on this?
There could well be a problem with building it a a whole project, maybe a link error? More likely it has not been set up properly for eclipse.
Are you using helios? Autotools?
