Hi,
I find it odd that -j breaks the idiomatic `make clean all check
install'. Consider
$ cat makefile
#! /usr/bin/make -f
SHELL = /bin/bash
all:
sleep 0.$$((RANDOM % 10)) && echo all
clean::
sleep 0.$$((RANDOM % 10)) && echo clean
check::
sleep 0.$$((RANDOM % 10)) && echo check
install::
sleep 0.$$((RANDOM % 10)) && echo install
Everything is normally slow, but correct.
$ make -s clean all check install
clean
all
check
install
$
I want the more faster parallel, but still correct, so try
$ make -sj clean all check install
all
install
check
clean
$
It seems a design flaw that I must
make -sj clean && make -sj all && make -sj check && make -sj install
or the icky
eval 'make -sj '{clean,all,check,install}' &&' :
How do I tell make that the targets I explicitly name, which don't
depend on one another, should be built sequentially, but parallelism may
be used in building them?
In looking at other makes, I see pmake/bmake has .WAIT and .ORDER;
http://manned.org/pmake.1 But I'm after something at the command line
that keeps things brief, e.g. `make -sJ ...'.
Cheers, Ralph.
