Experimental Physics and
Industrial Control System

Hi Ralph,

I can't try this myself right now but it might be possible to do that already, using a target specific setting of the HOST_OPT and CROSS_OPT variables. Something like this:

epicsCalc$(OBJ): HOST_OPT=NO
epicsCalc$(OBJ): CROSS_OPT=NO

Note that the target involved is the .o file, not the final executable. Not sure where in the Makefile that belongs either.

It might be worth looking at combining the two _OPT variables to simplify that, but I don't remember how they get used.
