Hello,

 

I am doing the following:

 

import feature ;

 

feature.feature test : E A B C D : composite ;

feature.compose <test>A : <define>_TEST=0 ;

feature.compose <test>B : <define>_TEST=1 ;

feature.compose <test>C : <define>_TEST=2 ;

feature.compose <test>D : <define>_TEST=3 ;

feature.compose <test>E : <define>_TEST=4 ;

 

exe main : main.c : <test>A ;

 

And for some reason, _TEST=4 is always set even though I am specifying that <test>A  (_TEST=0 is also set) should be used. I am obviously misunderstanding the documentation regarding the default value of test since I would have expected it to not be used in this case.  Can someone explain why this is happening and how I can have a default value set when <test> is not specified but when it is specified, have it use the specified value not the default?
