Debugger exits: No executable specified, use 'target exec'

Post by paulkinzelman » Fri Feb 25, 2011 6:25 pm

I'm using CodeLite V2.9.0.4684 on VistaSP2 with one workspace and two projects, a DLL and a console app that uses the DLL called in as a library.

I can compile the DLL and the console app, and I get a .EXE file that I can run in a DOS window. However, when I try to run it under CodeLite to debug it, I get in the debugger window:

No executable specified, use `target exec'.

There's probably something simple that I don't have set up but I can't find it.

I also tried compiling all the sources together (no DLL) and I get the same error when I try to debug.

Starting debugger : gdb --command="C:\Users\paulkinz\AppData\Local\Temp\codelite_gdbinit.txt" --interpreter=mi ""
Note the "" at the end, this means that there is no executable to debug...

Open the project settings | General

and make sure that you have executable specified in the "Program to Debug / Run" section

I left everything the default:
Program: ./$(ProjectName)
Working Folder: $(IntermediateDirectory)
Program Arguments: <blank>
Use separate debug arguments <unchecked>

In fact, I compared this section to the section in the Workspace that does work and those entries are identical. And the one that doesn't work actually does create an executable file that I can run from a DOS prompt.

But you're right, that line shows null for the executable, and the one that works shows an object there. So I have something corrupted wherever that line gets the executable from. If you don't have any specific ideas to look for, I guess I'll just create a new workspace/projects and see if that fixes it. But it might be nice to know how/where that got corrupted so I'll wait until I hear back from you.

BTW, when I hover over "Use separate debug arguments" you've got a typo: "speicified"

The question is whether or not you left the 'Output File' to use the default.

From the gdb log, I assume that this project is a DLL project?

If this is the case, then you should specified an executable to debug and not the DLL. Can you try and set an executable without codelite's macro (use the [...] button to select an executable)

In addition, can you please attach here the .project file so I could look into it and see what went wrong?

Well, that's strange. I'm doing today exactly what I did the other day when I was having the problem and today the gdb line you noted does not have a null file in it and it's working properly. Sorry for the intrusion. Feel free to delete this entire thread because at this point it appears that it must have been operator-error though I have no idea what.

The workspace had a DLL project and a top-level console app project. I even changed it to be a single project to compile everything into one top level console app and that didn't help. I understand that the DLL won't run standalone. Oh well...

I just today ran into this same problem again when I tried to create a new workspace so I thought I'd post what I found in case others stumble over the same problem.

The project was simple, just one console executable workspace and one DLL workspace used by the other one.

By looking into the .project file, I think what I did was to create the DLL workspace as a second executable instead of a DLL. In 'settings', the Project Type was "Executable" instead of Dynamic Library. And that screwed things up.
