Eclipse CDT project built but “Launch Failed. Bina

问题:

Windows 7, Eclipse CDT, Juno Service Release 2, Cross compiler.

Projects do compile executables generated, but Eclipse can't see them; therefore 'Run' fails. Executables are placed in Debug directory. Double click or command prompt call on compiled executable works without problem.

How can I solve this?

回答1:

This happened to me and I found a solution, see if this works for you:

Once you have built your project with the hammer icon:

1. select "Run".
2. Run Configurations.
3. Choose "C++ Application".
4. Click on the "New Launch Configuration" icon on the top left of the open window.
5. Select "Browse" under the C/C++ Application.
6. Browse to the folder where you made your project initially.
7. Enter the Debug folder.
8. Click on the binary file with the same name as the project.
9. Select "OK".
10. Click "Apply" to confirm the link you just set.
11. Close that window.

Afterwards you should be able to run the project as much as you'd like.

Hopefully this works for you.

回答2:

Simply select the project and press CTRL + B.

I think I found solution - proper binary parser must be selected so Eclipse can recognize the executable:

Select the project, then right-click. Project->Properties->C/C++ Build->Settings->Binary Parsers, PE Windows Parser.

I.e. if Cygwin compiler is used then Cygwin parser should be used.

That worked for me at least for Cross-compiler (both on Windows 7 and Ubuntu 12.04). On Linux, I use Elf parser.

If anyone has the better solution, please advise.

回答4:

On a Mac, If you also have a similar problem, as Nenad Bulatovic mentioned above, you need to change the Binary Parsers.

Press Command + I to open up properties (or right click on your project and select property)

Make sure you select Mach-O 64 Parser.

回答5:

in my case this is the solution to fix it. When you create a project select MinGW GCC from the Toolchains panel.

Once the project is created, select project file, press ctrl + b to build the project. Then hit run and the the output should be printed on the console.

first i had to click a little arrow button that opens a menu containing "Run Configurations",

then in the following window, i had to click "C/C++ Application", followed by a textless button with a green + on it

then i had to press the "Apply" and "Run" button

and then eclipse could run/debug the program. :)

回答7:

For what it's worth, I had this problem - and the cause was invalid DWARF 3 info in the binary in the selected project (which didn't have any runnable binaries).

The way it work was something like this: I had two projects Main and Library. Main depended on the Library project and the former had an executable, while the latter just produced a static library (that Main linked against).

My run option was set to "Run/Debug -> Launch" setting was set to "launch current, otherwise last" as follows (see bottom right):

If I had the Main project selected, everything would work fine: it would launch the main project. If I had the Library project selected¹ it would fail with the error message given by the OP. The reason seemed to be this: since I had the Library project selected, the PE scanner would scan the binary files in the project to see if any were launchable, and because scanning was failing due to this bug the error message popped up before it ever got to "Launch the previously launched application".

I could work around it by:

1. Making sure the project I wanted to launch was selected, or ...
2. Changing compilers to one that made DWARF info that Eclipse could parse without failure, or ...
3. Selecting "Always launch the previously launched application" in the Run/Debug settings - although it might not be your preferred mode of operation.

¹ I wouldn't usually select the project directly, of course, it would be indirectly selected because I was working in one of the source files it contained.

回答8:

After trying everything here what worked for me was to grant execution permission to eclipse:

cd eclipse-installation-dir 
sudo chmod +x eclipse

Using Eclipse Luna on Ubuntu 12.04 LTS.

回答9:

Make sure that the folder name does not contain .c extension. When I removed the .c extension in my folder name it worked automatically.

回答10:

You need to click on the MinGW compiler when running the code. Failure to do this will cause the launch failed binary not found error.

回答11:

press ctrl +B and then You can use the Run button.

回答12:

I've got the same problem on Eclipse 3.8.1. For me it worked to set the artifact type to executable:

Right click on the project -> C/C++ Build -> Settings -> Build Artifact -> Artifact Type: Executable

Finally rebuilding the project produced the Binaries entry in the Project Explorer.

The video link below illustrate these steps in more detail:

1. Create Empty project
2. Choose linux Gcc compiler
3. Right click on project choose " source folder "
4. Name it " src "
5. Right click on src folder choose " source file "
6. Start coding
7. Save project
8. Build project
9. Run project
