oops, I believe it is not correct to say "Swig bindings use some C++
API", but it is nevertheless sometimes hard/not possible to mix VC and
MinGW when developing for Windows

MinGW gcc generates .dll.a files, which are the link libraries, but it
can also use the plain dll to link against.
However, when you mention gdal16.dll, it sounds like you're trying to
link against a GDAL dll that was generated with VC. The C++ API is
very difficult to use from such dll when you're developing with MinGW
if not impossible. I, for one, have never succeeded. The Swig bindings
use some C++ API, which have so far prevented me from using "an
official" binary gdal dll for the Perl bindings for example.

Hi to everyone,
I'm trying to make a plugin for GDAL. So I need to use some
GDALDataset methods
(AddBand, GetDriver, setGCPs, ...).
When I compile my code with MinGW it's all OK, but when MinGW starts
linking it
doesn't found these methods and give me "undefined reference" to all
them.
In makefile I added to LNK_FLAGS variable both gdal16.dll and its
path. I tried
to use gdal_i.lib of 1.5 version too, but nothing appened.
If it's useful I copy CPP_FLAGS following:
CPPFLAGS:=-Wall -DCSK_PLUGIN -fPIC $(GDAL_INCLUDE) $(HDF5_INCLUDE)
$(CPPFLAGS)
CPPFLAGS:= -DH5_HAVE_HIGH_LEVEL_API $(CPPFLAGS)
CPPFLAGS:= -DWIN32 -DDLL_EXPORT -DPIC $(CPPFLAGS)
