Not always, since -j1 is also a parallel build mode so it fails
on some makes much the same way as -j2 does. "make" is safer...
We can easily change that of course. I obviously didn't realize
there was any difference at all between "make" and "make -j1". I
don't see how "make -j1" could be thought to be a parallel build
mode, since it will run only 1 job at a time, hence no jobs in
parallel...
I think it only runs one at a time anyway, just that the deps fail.
Or something like that, it's not like I actually digged into it...
Just noticed that "make" works and "make -j1" does not. Besides,
that "-j1" argument seemed rather silly to me in the first place ?
It's not so much about other OS platforms as it is about different
/usr/bin/make, as you can test on Mac OS X by pointing the symlink
at bsdmake instead of the default gnumake.
But MacPorts is documented as using GNU make by default. That's
build.type. MacPorts should be using GNU make by default on all
platforms unless the port sets build.type to bsd. Is this not the
case?
If nothing is set for build.type, it uses system make:
if {![exists build.type]} {
return [findBinary make $portutil::autoconf::make_path]
}
So it was using -j1 for bsdmake as well ? Or actually it was using
"fail" (2) for -j until the default value was changed from 0 to 1.
So "whatever the system provides" is the default value, then it
can be explicitly set to GNU for the 0.01% of the ports that care.
This makes it less portable, if it requires "Mac OS X" and "Xcode"
instead of explicit dependencies like Tcl or GCC... That's all.
Yeah. I guess all we can do is fix things when problems are reported.
No, what you *could* do instead is saying "So what ? We don't care !"
and just have MacPorts require Mac OS X (10.5+ ?) and be done with it.
I don't think that MacPorts could ever be a portable build system,
I was just making sure that it runs on Darwin OS and now FreeBSD...
Partly because I think Open Source is important, and partly because
I don't have a new Mac to join in on the Snow Leopard crash fest...
