thank you for your reply, now I am confused that besides write makefile with plugin support in dirver dir, are there other changes? and are there any changes in our partner's dirver source? IN my opinion, gdal_FOO.dll is just the interface between FOO.DLL and gdal16.dll, and our partner need provid their dirver as xxx.dll?

The best solution would be that your partner delivers to you its driver A compiled as a separate GDAL plugin (for example, if the driver shortname is FOO : gdal_FOO.dll with an entry point GDALRegister_FOO()). You then just have to define GDAL_DRIVER_PATH to point to the directory where gdal_FOO.dll is. Be careful : you and your partner must use use the same major GDAL version (identical X if GDAL version is 1.X.Y) to compile & run against, otherwise there is a risk of C++ ABI incompatibility. As far as your driver B is concerned, compiling it as a plugin or fully integrated in your GDAL source tree is just a matter of conveniency. See http://trac.osgeo.org/gdal/browser/trunk/gdal/frmts/hdf5/makefile.vc for an example of a makefile with a plugin target. gispowerfan a écrit : > Hi > > I want to ask a question about how to implement the driver > for gdal.
