Eclipse CDT Invalid Project Path

Question

I have a C project that is built using a makefile, Eclipse constantly warns about \"Invalid project path: Duplicate path entries\", but I cannot figure out what the hell it

Answer 1

You should check if you have manually defined a symbol that eclipse can figure out from your makefile. I have a project that has a manually written makefile and the problem was solved by removing symbols that I had manually added to C/C++ General -> Paths and Symbols -> Symbols.
