no executable specified use 'target exec'

[Rory]

I would like to debug a dll by running it through a host program. I do this on Linux all the time without a problem, but on Windows I'm getting a 'no executable specified use target exec'. I've specified the program to run/debug by clicking the browse button and selecting the .exe in the project settings. Any ideas as to what the problem might be? The dll is building fine, here's my build output:

Please provide the debugger log
HOW TO POST

[Rory]

That's the thing, I can't get to the debugger output as the debugger never gets going? Just as it is about to launch I get that no executable message? I've attached the project file. You'll see the program I've selected to run the .dll with there.

[eranif]

The fact that you got the "no exe" message means that the debugger started properly - but it could not find an executable to debug
If the debug layout closes too quick - restore it from: Perspective -> Debug and copy / paste the debugger output tab content here

[Rory]

Thanks, I didn't know about the perspective menu commands! Here you go:

Using gdbinit file: C:\Users\Rory\AppData\Local\Temp\codelite_gdbinit.txt
Current working dir: C:\Users\Rory\Documents\SourceCode\cabbageaudio\CabbageCodLite\Plugin
Launching gdb from : ./Debug

It seems that gdb is searching for the executable at: "../../../JUCE/extras/audio plugin host/Builds/CodeBlocks/bin/Debug/Plugin Host.exe"
The working directory is set to:

C:\Users\Rory\Documents\SourceCode\cabbageaudio\CabbageCodLite\Plugin\Debug

Can you confirm that this file do exists?
If not, try fixing this from the "General" page of the project settings

[Rory]

Yes, they exist. One thing that I find strange is this:

Current working dir: C:\Users\Rory\Documents\SourceCode\cabbageaudio\CabbageCodLite\Plugin
Launching gdb from : ../../cabbage/Builds/Windows/bin/Debug
Starting debugger : gdb --command="C:\Users\Rory\AppData\Local\Temp\codelite_gdbinit.txt" --interpreter=mi "../../../JUCE/extras/audio plugin host/Builds/CodeBlocks/bin/Debug/Plugin Host.exe"

The current working dir is set to "C:\Users\Rory\Documents\SourceCode\cabbageaudio\CabbageCodLite\Plugin" yet as you can see from the screenshot, it should be set to the debug folder in that dir?

The debug output also reports:

DEBUG>>&"C:\\Users\\Rory\\Documents\\SourceCode\\cabbageaudio\\cabbage\\Builds\\Windows\\bin\\Debug/plugin: No such file or directory.\n"

When in fact I think it should be CabbagePlugin.dll? I'm using a custom make file, is there a way to explicitly set the dll file name? I've attached the latest debug output.

[eranif]

The current working dir is set to "C:\Users\Rory\Documents\SourceCode\cabbageaudio\CabbageCodLite\Plugin" yet as you can see from the screenshot, it should be set to the debug folder in that dir?

And this is what codelite does:
"Current working dir" - means that this is the current working directory (before it changes it)

Launching gdb from : ../../cabbage/Builds/Windows/bin/Debug

This is where codelite does the "cd" and this is what you need to confirm:

Does this directory ("../../cabbage/Builds/Windows/bin/Debug") exists when your working directory is set to "C:\Users\Rory\Documents\SourceCode\cabbageaudio\CabbageCodLite\Plugin"?
If not, try to clear the "Working directory" and reselect the binary to debug "Program"

Looks like it was the spaces in file name and path. It's all working fine now. I've been using CodeLite on daily basis for the past year on Linux and have found it to be nothing short of perfect for my development needs. Hopefully, I'll have the same experience on Windows.
