Hi,
I am a newbie in Xerces-C++. I managed to write my first few
applications without any problems. But I am having problems to write a
plugin (dll) to a third party application. This third party application
uses Xerces 2.7.0. My dll also uses Xerces 2.7.0 but for totally
different purposes. As I do not know the internals of the application I
cannot figure out what is happening, but the application returns an
error when tries to link to my dll function specifically where I
initialize Xerces. If I use Xerces 2.6.0 (a different version) for my
plugin, everything seems to work ok. This is a good temporary solution,
but I would like to know what is going on. So I guess I am forgetting to
declare something, define perhaps a namespace, etc. Does anyone have an
idea of what I might be doing wrong? The application developers told me
they use XERCES_CPP_NAMESPACE_USE and so do I on my plugin.
Using XERCES_CPP_NAMESPACE_USE has no affect on the actual C++ namespace
for the Xerces-C version you're using. This sounds like a conflict between
how the other library is using Xerces-C and how your plugin is using it.
If you can't find out any details about how the other application is using
Xerces-C, then your best bet is to build a custom version using a unique
file name, and a unique C++ namespace. For example, you might append a
string of characters to both the file name and the C++ namespace that
associate it with your application.
