             Bug #: 11660
           Summary: set-xcode-analyzer doesn't work with custom Xcode
                    install locations
           Product: clang
           Version: 3.0
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek at apple.com
        ReportedBy: e28eta at yahoo.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


This is with checker-258.

The set-xcode-analyzer script has a hard-coded assumption that Xcode is located
at /Developer

This is not true on my system, and when I run it I see:
    $ ./set-xcode-analyzer --use-checker-build=/checker-258
    (+) Using Clang bundled with checker build: /checker-258
    $

It looks like it succeeded, but it never found the Clang LLVM xcspec, and so
never made a change. When I run analyze, it still uses the clang binary bundled
with Xcode.

I think it should be using `xcode-select -print-path` to find the path to the
current Developer directory. According to the man page for xcode-select, "This
is a recommended way for scripts and other tools to locate the current Xcode
folder."

I think it should also print some sort of confirmation/error based on whether
it actually changes Xcode to use the new/changed checker.
