Why do I get "Starting the debuggee failed: No executable file specified."?

(1/2) > >>

crobar:
I have a makefile based project I would like to debug. when I attempt to do so I get the debug log below and the error  "Starting the debuggee failed: No executable file specified.". The place were I would expect the program name to be is empty, there are no spaces in the file name (I gather this causes problems from other forum posts). The program runs exactly as expected when I just run it from code::block without debugging.

Could anyone explain what I might be doing wrong?

BlueHazzard:
i think you have to set your output file (code blocks does not know how your output file is called, if you use custom makefiles)
Project->Properties->Build Targets->Output Filename

Set this for your debug target...

greetings

Actually I only have one target 'all', but I had already set the option Project->Properties->Build Targets->Output Filename for this target (remember the program runs fine when I just use the 'run' option). However, just to be sure I created a 'Debug target, but it makes no difference. Thanks though.

Jenna:
First:
please use code-tags, if you post log-content or sources, it's much more readable.

Is the filename mentioned in the log really the executable ?
Can you run it through gdb on a console ?
What shows "file <exename>" ?

BlueHazzard:
On windows i had the same problem by using different compiler and debugger versions
ex. mingw64 compiler but tdm gdb
