I need to get the nth dependency file from a rule, something similar to $n in bash. I need this because I'd like to feed in individual dependency files as options to the build program.
Here's an example:
dep.o: dep.src config1.cfg config2.cfg parse -cfg1 $2 -cfg2 $3 -o $@ $< Is it possible?
301
makefile Variables Automatic Variables Within the context of an individual rule, Make automatically defines a number of special variables. These variables can have a different value for each rule in a makefile and are designed to make writing rules simpler.
The variable $@ represents the name of the target and $< represents the first prerequisite required to create the output file.
$(patsubst PATTERN,REPLACEMENT,TEXT) Finds whitespace-separated words in TEXT that match PATTERN and replaces them with REPLACEMENT. Here PATTERN may contain a % which acts as a wildcard, matching any number of any characters within a word.
dep.o: dep.src config1.cfg config2.cfg @echo the second preq is $(word 2,$^), the third is $(word 3,$^) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
