Licensing and Porting Issue for the CMS (ActiveMQ-CPP) on Visual Studio 6
from Visual Studio 8
I have downloaded activemq-cpp-2.0.1-src (i.e. CMS 2.0.1) from
http://activemq.apache.org/cms/download.html
It is provided with vs2005-build (Visual Studio 8).
Now, as our project is in vs2003, I am trying to build (port) it in Visual
Studio 6, but I am getting following errors, which means I will need to make
some modifications like adding some typedefs or some fix to get around some
‘type’ issues that causes compiler errors under Visual Studio 6.

Now as CMS (ActiveMQ-CPP) is the Apache 2.0 licensed, so do I need to
release it back to the community, the porting changes that I make to the
current CMS library which is Visual Studio 2005 build, OR I wont be able to
make the changes OR what other licensing issues may arise in our case.
PLEASE CLERIFY.
