x_examples.cpp

In a text editor, open x_examples.cpp. Find the GOpen() call and update the address to match the desired hardware. See the documentation for GOpen() for address formatting options. Don't forget -s ALL if data records, interrupts, and messages are to be tested.
Find the #if 0 preprocessor block enclosing the example calls. Change to #if 1 to run the examples. Comment out the function calls to be avoided. Note some calls attempt to move motors and not all functions are compatible with all Galil products.

Compile

$ g++ x_*.cpp gclib.0.dylib gclibo.0.dylib -o example

Run

$ ./example
