Re: Re: [gdal-dev] driver question?

[gispowerfan]

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?

Best

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.
