When linking the project, object files are include in the build twice. Once in the src\... and once in ..\release\src\... So if there is a file webapp.cpp the link command line as src\webapp.o and ..\rel;ease\src\webapp.o

Obviously this results in many duplicate symbols and such.

It looks like this comes from the macro ${INPUTS} containing twice the necessary information.

No amount of "cleaning" or deleting of objects fixes this.

The project use to build.

I think you messed up the build configurations.
I presume files in src\* and release\src\* were meant to be different build configurations.
Did you really want debug\src\* instead of just src\*?

Create a new HelloWorld project and build the Debug and Release configurations to see what was expected.

I was able to get things back to normal by:
1. exiting Eclipse
2. removing the ..\release directory tree
3. recreating the ..\release directory tree
4. restarting Eclipse
5. performing a "Refresh" option on the project
6. doing a "Clean Project"
7. doing a "Build Project"

Now, the project builds as one would expect.
