[gdal-dev] GDAL / libKml interaction causes app to crash

[Clay, Bruce]

This question is most likely a problem with libkml.  I did post a
message on the libkml forum as well.  My apologies if you are subscribed
to both asnd getting this message twice.

 

I am working on an application that uses GDAL and libKml.  Everything
was going fine until I added KmzFile::CreateFromKmlFilepath to create a
kmz file.  The application crashes in GDAL space during start up while
registering the plugins.  The only common link I can find is both
applications are using zlib and minizip.  I downloaded the latest
version of zlib which appears to be the same one currently used by
libkml as well as GDAL. Even though I use  zlibstat.lib in my
application I still get 15 unresolved externals.  In the original setup
I linked in minizip.lib but minizip is only created as an executable in
the current version.  Some of the unresolved externals are shohw at the
end of this message.

 

Is there a known work around to this problem?
