make-first-existing-target [-c cmd] target1 [target2 ...] --
The design of make(1) causes difficulty when you know that a Makefile
probably has one of several standardized target names, and want build
machinery to run exactly one of them, propagating any errors. make(1)
will exit 2 if a target does not exist, but an existing target may also
exit 2 due to some other failure. Makefiles cannot be reliably parsed
to find targets by anything less Turing-complete than make, and make
itself does not provide a way to enumerate the targets in a Makefile.
It may not even be possible to enumerate the targets in a Makefile
without executing part of it. (Proof of this is left as an exercise for
This program avoids the problems described above, by attempting to call
each specified target in turn, until it observes make actually doing
something for one of them.
This can be used to specify the make command to run. Default is
The exit status is 0 if at least one target existed and was
successfully run, and nonzero otherwise.
