You probably have Frank's OpenEV version and the gdal lib is built with some extra features which I
don't really know about. But why are you linking with gdal_i?
If you installed OpenEV in c:\openev_fw for example, you could use "-Lc:/openev_fw/bin -lgdal12" and
it should work (ie, ld will link with gdal12.dll). Maybe it will also solve the problem you mention
in your later post.

I tried that fusion thing myself and made it as an OpenEV tool. Maybe you saw my posts about that a
few weeks ago...

It's there if you want to have a look: http://pages.infinit.net/starged/openev/fusion.py

Good luck!
