"Search for duplicate source files on the path" doesn't seem to be working with gdb launch [message #521270]

I have more than one main.cpp under my project root. When I launch my Debug Launch Configuration, eclipse pulls up the wrong main.cpp. I can see that gdb is debugging the correct application, bc the variables and line number in main correspond to the correct main.cpp, but the eclipse debug view just opens the wrong file.

I have "Search for duplicate source files on the path" checked, and have tested this with many launch configs (using gdb, gdb/mi). I have deleted and recreated my workspace and have the same results. Also I can debug the same application from command line gdb w/ no problems.

Any ideas what is going wrong? What I can try to fix or workaround this problem?

Thanks,
Tim

You can try to use DSF-GDB instead. To get to that other GDB integration, click on the hyperlink at the bottom of any of your launch tabs, and select "GDB (DSF) ..."

Or in your current launch's Debugger tab, you can try the "Use full file path to set breakpoints" and see if that helps.

Thanks Marc. I was using gdb/mi before. I tried checking "Use full file path to set breakpoints" while using the Standard Create Process Launcher. Same problem.

I switched my launcher to use gdb instead of gdb/mi and same problem.

I switched my launcher to use GDB (DSF) Create Process Launcher (which assumes gdb/mi debugger) and same problem.

All along the way, I checked to make sure that "Search for duplicate source files on the path" is checked.

Using any of the above launchers, if I rename the second main.cpp (which is alphabetically hit before the main.cpp I want on the path, and is not part of the executable I'm debugging) and launch, the correct main.cpp is opened.

Seems like "Search for duplicate source files on the path" isn't working, however unlikely. Another clue - I am using shared launcher file, not a local (temp) one. At one point I saved the launcher config file before/after changing "Search for duplicate source files on the path" just to make sure the change was actually reflected in the file and I did see an element added after.

Any more ideas?

I'm not knowledgeable about this duplicate path thing, so if it seems like a bug, I'd open a bug in bugzilla.

Found another thread here with a non-sensical yet effective workaround that works for me: http://www.eclipse.org/forums/index.php?t=msg&th=75411&a mp;start=0&

Still looking for an explanation, but let's do that on the other thread. I apologize for the redundancy.
