Debugger found the wrong source file - how to fix? [message #235454]

I've been clever enough to use the same (base) file name for two different
source code files on two different sub directories under my project.

When I started a debug session just now in order to analyse a core file,
the debugger picked up the wrong one. Is there any way to tell it to use
the other (correct) one instead? Also, this seems to indicate that the
debug setup searches for files on basename. Shouldn't it try the absolute
path given in the debug tables first?

Note that gdb from the command line did not have this problem for the same
executable and core file.

Setup a debug configuration within Eclipse. In the "Debugger" tab there is
an option "Use full file path to set breakpoint". Try this.

Didn't help, I'm afraid... However, when I looked into the problem again
right now, I think I found a solution. I did:
1. Open the debug configuration in question...
2. Select the "Source" tab.
3. Select "Default" from the path list, then press "Remove".
4. Click "Add...", then select "Absolute File Path".

And everything seems OK. Which doesn't really make sense, since "Absolute
File Path" was also included as the topmost entry under "Default"...

But you removed the relative paths in step 3. That did the magic.

True, but like I said, the "Absolute File Paths" is listed above any
relative path in the defaults. Shouldn't that mean it takes precedence?

My team is having the same problem with multiple main.cpp files in the project. It seems the only way to fix it is if the ONLY entry in the Source Lookup Path in the Launch Configuration is Absolute File Path. When I add the project root to the Source Lookup Path, either before or after Absolute File Path, the problem returns.

This is counter-intuitive, and I am very leery of accepting anything using an absolute file path bc my team shares eclipse project files and launch configuration files.

Can anyone explain why this behavior is so? What does this Absolute File Path entry mean and why does source file resolution only work when it is the only item in the list?

Can I share launcher config files if I have Absolute File Path in the Source Lookup Path?

Thanks!
Tim
