            Bug ID: 21552
           Summary: Bindings/Go/go.test fails when there's no
                    c++11-capable compiler in the environment
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Core LLVM classes
          Assignee: unassignedbugs at nondot.org
          Reporter: hans at chromium.org

    Classification: Unclassified

Bindings/Go/go.test fails on my machine when running in an environment that
doesn't have a C++11-capable compiler on PATH.

>From what I understand, the test runs cmake, inputs flags based on llvm-flags
and then tries to build parts of LLVM, which seems a little brittle.
