Re: Target-specific variable in subdirectory problem

[Sven C. Dack]

Hello,

try it with the following rules:

test-%: $(eval FOO = BAR)
test-%:
    echo $(FOO)

$ make test-stem
echo BAR
BAR
$ make subdir/test-stem
echo BAR
BAR

I cannot tell you why it fails in your example. My guess is that it's 
just not good practise to use a plain assignment for a prerequisite and 
that it's only working for backwards compatibility and not meant to be a 
full feature. I'm not the authority on make and your guess will be as 
good as mine.

Cheers,

Sven
