I've just done some programming for a ADSP-21469 in VDSP5.0.
Building the project has finished without problems.
So my next step was to export the default makefile (Project->Export Makefile...) and included that file again into my project as described in the Help.
Trying to build the project failed with the messages
C:\Program Files\Analog Devices\VisualDSP 5.0\gmake-378.exe: Nothing to be done for `DebugNWC'.
Build completed successfully.
C:\Program Files\Analog Devices\VisualDSP 5.0\gmake-378.exe: *** No rule to make target `Debug'. Stop.
Tool failed with exit/exception code: 2.
Build was unsuccessful.
I have no idea why this does not work!
