ONI_EXPORT_DRIVER macro uses undeclared XN_NEW and XN_DELETE about openni2

[piedar]

This is still a problem in OpenNI 2.2 Alpha from http://www.openni.org/openni-sdk/. When I try to compile a driver against Include/Driver/OniDriverAPI.h, I get

../src/DeviceDriver.cpp: In function 'void oniDriverCreate(OniDriverServices*)':
../src/DeviceDriver.cpp:271:1: error: expected primary-expression before ',' token
../src/DeviceDriver.cpp:271:1: error: 'XN_NEW' was not declared in this scope
../src/DeviceDriver.cpp: In function 'void oniDriverDestroy()':
../src/DeviceDriver.cpp:271:1: error: 'XN_DELETE' was not declared in this scope

Line 271 contains my call to the ONI_EXPORT_DRIVER macro.

I'm guessing no one else is writing OpenNI2 drivers so this is low priority. In any case, the workaround is simple:

// macros defined in XnLib (not included) - workaround
#define XN_NEW(type, arg...) new type(arg)
#define XN_DELETE(p) delete(p)
ONI_EXPORT_DRIVER(FreenectDriver::Driver);
#undef XN_NEW
#undef XN_DELETE
