             Bug #: 13451
           Summary: clang-check doesn't find file
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: nicolasweber at gmx.de
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


I tried playing with the compilation db format again.
http://clang.llvm.org/docs/JSONCompilationDatabase.html says "file" should be
relative to "directory", yet clang-check seems to not process this correctly
(or my json file is wrong, but as far as I can tell it's not):
