OK. I've reproduced the problem with my setup. Firstly it's not a C++ problem - the same thing occurs with the C drivers. I wondered if it is related to the dynamic drivers however the drivers appear to load ok. It also occurs with postscript and xwin drivers for me so it's not specific to a driver. Running the examples with the -debug option doesn't reveal any differences between the dynamic and static cases. In the case of the postscript driver the statically linked output is not empty - there are a whole series of drawing commands in the output file, however the coordinates are all the same. Maybe one of the developers can throw some light on this. Andrew P.S. Given that you have (I presume) compiled with dynamic drivers is there any particular reason you want to statically link in the plplot library? To use the program on another machine you would also need to distrubute the drivers in plplot/lib/plplot/driversd/.
