[gdal-dev] How can you use GDAL from a process that has already loaded some other app's xerces-c_2_7.dll?

Jason,

It seems clear that I did not use a stock binary and have in fact compiled
this Xerces myself (actually I presume I inherited from Howard's buildkit).

I'm going to start by rebuilding the stock binary without xerces, and we
can think about where to go from there.  Potentially the GML driver could
be offered as a plugin.  I will note that the xerces I used was from OSGeo4W
which is likely to run into similar issues in the future.  So if we do a
renaming it would likely be "xercesc-2.7-osgeo4w.dll" or something similar.

I have filed a ticket for OSGeo4W on the issue:
