To build the harness use ./build_opv_harness.sh +This will create a debug version of the shared object +libopv.so. The command line +gs -sDEVICE=opvp -sDriver=./contrib/opvp/libopv.so -o output.txt -f ./examples/tiger.eps +can then be used. + +This command should create a file called +opvp_command_dump.txt that contains the calls and +the parameters made to the client API. Note that the +harness itself has to rely upon globals. To do otherwise +would require a to change the client API, which we +do not own.
