[cfe-dev] set-xcode-analyzer requires Python 2.7.0+

[Jonathan Sauer]

Hello,

I was just trying out clang's static analyzer and, following the instructions at
<http://clang-analyzer.llvm.org/xcode.html>, set XCode's analyzer to my build of
clang TOT using the following command line (in myLLVM/llvm/tools/clang/tools/scan-build)

./set-xcode-analyzer --use-checker-build=myLLVM/build/Release+Asserts/bin/clang

This resulted in the following error:

(+) Using Clang located at: myLLVM/build/Release+Asserts/bin/clang
Traceback (most recent call last):
  File "./set-xcode-analyzer", line 88, in <module>
    main()
  File "./set-xcode-analyzer", line 78, in main
    xcode_path = subprocess.check_output(["xcode-select", "-print-path"])
AttributeError: 'module' object has no attribute 'check_output'


This is because OS X 10.6.8 (which I'm running) only has Python 2.6.1 installed, but
"check_output" was introduced in 2.7.0 (<http://docs.python.org/library/subprocess.html>).

The change to set-xcode-analyzer was made with r151179 to make the script work with
XCode 4.3 (which I assume can be installed in a different location than /Developer).

Of course it's no problem to locally undo this change; I am just wondering if the above
is the indented behavior on Snow Leopard.
