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

Here I just found another way to re-detect the path automatically:

1. Open "Workspace Settings-> C/C++ -> Build -> Settings -> Discovery"
2. Find "CDT Build-in Compiler Settings [Shard]"
3. Click "Clear Entries" and "Reset" button on the right
4. Rebuild projects and Done

Hope this will help.
