Re: [Question] How can i stop build immediately in build fail?

[David Boyce]

It may be a reasonable feature request but it also may not be that
hard to implement with existing functionality. Here's one approach:

% cat makefile
SHELL := $(abspath shx)

.PHONY: job
job: job1 job2

.PHONY: job1
job1:
        sleep 3
        exit 1

.PHONY: job2
job2:
        while echo ok; do sleep 1; done

% cat shx
#!/usr/bin/env python

import optparse
import os
import subprocess
import sys

if '__main__' == __name__:
    parser = optparse.OptionParser()
    parser.add_option('-c', '--command', type='string',
                      help='Command to execute')
    (opts, args) = parser.parse_args(sys.argv[1:])

    rc = subprocess.call(opts.command, shell=True)
    if rc != 0:
        print 'stopping make!'
        os.killpg(0, 15)
    sys.exit(rc)

% make -j2
sleep 3
while echo ok; do sleep 1; done
ok
ok
ok
ok
exit 1
stopping make!
make: *** [job2] Terminated
make: *** [job1] Terminated
Terminated

I implemented the replacement shell in Python but it could use any
language. You just need to kill the process group once the first
recipe fails.
