hello everyone!
i want to process image data using IDL,so the first step is to
read the data, the format of my data is in HDF, the code i writed as
follows:
IDL> a=dialog_pickfile()
IDL> hdfid=hdf_sd_start(a)
unluckily i encounter the error, the message is:

HDF_SD_START: Unable to start the HDF-SD interface.
Execution halted at: $MAIN$
what's wrong with it? please help me or give me some hints about this
problem!

thanks
