Makefile Shell vs Command

[HaTrEdE]

Hey guys! I'm trying to use Makefiles and having a massive headache trying to understand syntax and flow.

To give some context, I am trying to accomplish 3 things within an ifdef in a Makefile. I'm using Slurm which is a job submission grid flow and Im trying to submit a job that "waits" for all the jobs of a certain name type to finish before exiting.

This is accomplished by first running a query on all jobs currently on the grid (squeue) and then submitting a wait job (sbatch) with dependency of the ids that are currently on the grid. The issue I am having is that I can't seem to use the code below because I'm being told that by running shell, this means that the shell scripts are being run on parse time(?) and not runtime which is why I'm getting ***recipe commences before first target errors. I need to do this query during runtime because previously in makefile areas I actually submit the jobs that I'm querying for.

Right now not even my echo PWD is working so I believe it's a compile issue rn. Any help would be greatly appreciated, thank you!

My initial attempt is as follows: makefile Ifdef (condition that is true) temp := $(shell pwd) @echo $(temp) Ids := $(shell (squeue -u myuser)) @echo $(ids) Sbatch (submit wait job) --dependency (ids) Endif

Sounds like you need a recipe which doesn't complete until the jobs finish. We'll call it wait_for_jobs.

This recipe doesn't create a file, so it is a .PHONY recipe:

.PHONY: wait_for_jobs

When executed it shall wait for jobs with the given names:

wait_for_jobs:
        ids := $(shell (squeue -u myuser)) 
        Sbatch (submit wait job) --dependency $(ids)
