Question

I need to make a Makefile, and it should have a run rule. However, the run requires some parameters.

Does anyone have any idea how I can pass arguments in when running a rule in a Makefile? I want to be able to run the run rule with arguments by typing make run foo bar.

I tried this, but it didn’t work:

run:
    make compile
    ./scripts/runTrips $1 $2 $PLACES $OUT $VERS

The parameters I want supplied are the first and the second.

When passing parameters to a make command, reference them like you would other internal make variables.

If your makefile looks like:

run:
        script $(param1) $(param2)

You can call it with the following syntax:

$> make run param1=20 param2=30

and make should call the script like:

script 20 30
