I haven't done any changes to the project settings, the only things I've done is adding files to compile and include path. I do this from a base project, both the base project and the project I am working on have the same linker configuration :

The base project compiles without troubles, the new one was fine until I added a source path and this error happens. I tried to delete the source files I added but it doesn't remove the error
