Error: No executable file specified

Suddenly my program runs and compiles without error but will not open the executable. I get error dialog:

Error Starting Executable... No executable file specified. Use the file or exec-file command

I think this may have started when I created a "Workspace" of the same name. I did searches开发者_开发知识库 for the error but found nothing that made any sense.

I would hate to have to copy my work over to a new project because of this. Help!

Could this be a bug?

If you are using GDB as default debugger (verify it under Product-Edit Scheme menu) you must specify the executable path that is contained under the app folder (Executable.app/Contents/MacOS/Executable).

Did you add target to your project? If not this might be the problem. Click the project name and then click plus button, then add your target.

Gian Luigi is correct. This is the output from gdb if you just run gdb and then type run.

I tried adding -exec=/path/to/MyApp.app/Contents/MacOS/myapp to the debugger command line but it didn't have any effect.

The easiest solution is to use LLDB instead.
