The Windows error message might be telling you that while it was loading the plugin library, that DLL was required to load another DLL(s), from the SDK probably, and that is not in the PATH.<br>

<p>- The filename is case sensitive: it must be gdal_netCDF.so/dll since the registration function is called GDALRegister_netCDF()<span style="font-size:12.0pt"></span></p>
<p>- You need to set the GDAL_DRIVER_PATH environment variable to point to the directory where the driver is</p>
<p style="margin-bottom:12.0pt">- You might find it easier when using master to use CMake: cmake -DGDAL_ENABLE_DRIVER_NETCDF_PLUGIN:BOOL=ON . That will work on both Linux and Windows</p>
