OK, using an online name demangler, I get the following:

activemq::core::ActiveMQXAConnectionFactory::ActiveMQXAConnectionFactory()
First off, I notice the string types are not matching, and each string
argument has an additional partner "std::allocator". There's something
going on there with which I am unfamiliar.
With that said, my suspicion is that these two are intended to be the same:
*First*
_ZN8activemq4core25ActiveMQConnectionFactoryC1ERKSsS3_S3_
activemq::core::ActiveMQConnectionFactory::ActiveMQConnectionFactory(
std::string const&,
std::string const&,
std::string const&)
*Second*
_ZN8activemq4core27ActiveMQXAConnectionFactoryC1ERKNSt7__cxx
1112basic_stringIcSt11char_traitsIcESaIcEEES9_S9_
activemq::core::ActiveMQConnectionFactory::ActiveMQConnectionFactory(
std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> > const&,
std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> > const&,
std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> > const&)
So then, why are they different? Again, not sure. The first thing that I
would check is that any flags that may affect the compiler's translation of
C++ code are the same on all the parts in the build. For example, in the
compile line provided, I see *-std=c++11* and then I wonder if ActiveMQ-CPP
was built with the same flag.
I take it ActiveMQ-CPP was built using the same arm cross-compiler?
Note that I just tried a small C++ compilation using -std=c++11, std=c++98,
etc and did not find any difference in the output.
Please let me know what you find.
