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
Tim

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've been trying to solve this problem with eclipse when trying to run a c++ project. I don't exactly know why it started saying that the program file does not exist because the exact same project was working fine before. All I did was add some more code and ever since, I could not build this project, I already tried changing the launch configuration in the project properties but it didn't really do anything. Has anyone encountered this problem, and if you did is there any way to solve it?
...Also it says that the "Program 'g++' was not found in path", which I don't even know why it's even looking for it in that path since I specified where the mingw64 HOME was, but if I create a new project or run an old project it builds and runs fine without any problems...

Go to Properties for your project, select Run/Debug Setttings, select "Edit",
Notice text box C/C++ application is empty, fill it by selecting "Search Project" in your debug directory for your .exe file
Hope this helps !
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'm trying to use the cpu of bochs in my graduate course project. I want to create a project of it in eclipse so I can modify it and compile it and also see the errors ...
I have the source code and I use visual studio's nmake to build, compile it. but the problem is that it doesn't report me the errors and the only way to know the error happens or not is to wait until nmake ends and see if the .exe file is created or not. after that the process of finding errors is a bad headache.
so I'm trying to use ubuntu OS and use eclipse. anyone knows how to create a project for bochs in this?
Also the more important thing is a tutorial that I can learn bochs cpu codes. because the official site's tutorial has no use.
haha,
I found it myself.
just go to bochs official site and download the source code for linux.
extract the zip file somewhere.
open a terminal and go to the extracted folder.
type:
./configure
this will check your system and set the values for the #define arguments in a file called makefile.
now open eclipse.(I assume that you have the c/c++ CDT). FILE>NEW PROJECT
In the opened dialogue open c/c++ tree, and select "Makefile project with existing code" and click next. next put a name for your project and in the "existing code location" browse the extracted folder. next select CROSS GCC as toolchain. then click finish.
there you go. now build the project and it should work.
remember that for running project you must give bochs command line arguments which is available in eclipse and you can find out how with a search in forums.
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 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.
