The command "gpr_tools -i GOPR0020.GPR -o GOPR0020.JPG -r 1:1" failed:

And I have the same problem with "./gpr_tools -i GOPR0020.GPR -o GOPR0020.PPM -r 1:1 -b 16".

1:1 mode is not supported yet as it would require full decode and de-mosaic. Please try 1:2 through 1:16

As this is intended as a VC5 RAW decoder to uncompressed RAW, a demosaic has not been included. This library and sample code was developed to help third integration into existing RAW tools. That said, a simple GPR -> JPG/PPM at full resolution could be useful for applications beyond RAW photo tools.
