---------------------------------------
Summary: Compiling with clang++
Key: AMQCPP-423
URL: https://issues.apache.org/jira/browse/AMQCPP-423
Project: ActiveMQ C++ Client
Issue Type: Bug
Components: CMS Impl
Affects Versions: 3.4.3
Environment: Redhat Enterprise Linux Server 6.3
Clang 3.0
Reporter: Steve Pietrowicz
Assignee: Timothy Bish
Priority: Blocker
We're trying to get our entire software stack running under clang. One of the
third party packages we use is ActiveMQCPP. We're using an older version of
the library, which builds, but results in an error when we try to use it (see
the last part of this message).
The ActiveMQCPP 3.4.3 package fails to compile under clang 3.0, first giving
many warnings in other files, and then the error in ExecutorService.cpp:

5 warnings and 1 error generated.
Version 3.1.2 of the library compiles, but throws an exception (out of range)
on in createConnection in AMQConnectionFactory.
I wasn't sure how to classify this issue and whether it should be classified as
enhancement request. Is there any plan to support clang in the future?
