Thanks Andy! Closer... it's in /usr/include/modbus/
I specified that. Now it doesn't fail on a missing type modbus_t, but
rather "undefined reference" to any modbus_write_bit etc functions. So
even though I did get that install for libmodbus to work, it just has
the header file. It's not able to find the definitions in a compiled file.
More ideas?

And same prob. It's looking for stuff in the libmodbus's modbus.h but
it's not seeing it somehow.
You could try giving it a complete path:
#include "/usr/share/modbus/modbus.h"
(quotes rather than braces, I think, for an explicit path)
Or, maybe
#include <modbus/modbus.h>
As libmodbus installs into a directory.
