Makefile for similar targets

[King Mir]

I want to have a number of make target in the following format:

test2:mylang.exe test2.mir test2.out.expect.txt test2.err.expect.txt
	./mylang.exe test2.mir >test2.out.txt 2>test2.err.txt
	diff test2.out.expect.txt test2.out.txt 
	diff test2.err.expect.txt test2.err.txt

So I want to have targets test1, test2, test3, ect., without having to manually that whole block of code and replace test2 with testx.

How can I do that?

By a separate 'configure' script ?

I'd rather use copy-paste then that. Seems too much to add one just for this.

[brewbuck]

all_tests.mk: test1.mir test2.mir test3.mir
    generate_test_rules.sh $^ > $@

-include all_tests.mk

Then write script generate_test_rules.sh which takes .mir filenames on command line and prints make rules for those tests to stdout. To add a test .mir, add its name to the deps for all_tests.mk target

That won't let run one test at a time. That does make me realize I don't need the testx preqs, just mylang.exe.

That won't let run one test at a time.

It doesn't run the tests at all, it just automatically generates the rules for the tests. You still run the tests by saying 'make test2' or whatever.

After doing some more searching, I came up with this:

test%:mylang.exe
	./mylang.exe $(addprefix $@,.mir) >$(addprefix $@,.out.txt) 2>$(addprefix $@,.err.txt)
	diff $(addprefix $@,.out.expect.txt .out.txt) 
	diff $(addprefix $@,.err.expect.txt .err.txt)

It seems to work.
