toolchain/49535: Examples in BUILDING don't work as-is
>Synopsis: Examples in BUILDING don't work as-is
>Arrival-Date: Sun Jan 04 14:30:00 +0000 2015
>Originator: Andreas Gustafsson

If you do a full installation of NetBSD using sysinst, including the
source sets, cd to /usr/src, read the BUILDING file, and try to run
the first example listed under EXAMPLES,
1. % ./build.sh [options] tools kernel=GENERIC
as an unprivileged user without specifying any options, i.e.,
$ ./build.sh tools kernel=GENERIC
the build will fail with:
ERROR: -U or -E must be set for build as an unprivileged use
If you do it as root, it fails with:
ERROR: Can't create top level object directory using make obj
I think having an example that works as-is would be helpful,
particularly to new users.
First of all, presumably the shell prompt in Example 1 should be
changed from "%" to "#" to indicate that the command is to be run as
root, because unprivileged builds are covered separately in example
As for the lack of a /usr/obj, there are many ways that could be
fixed, but I have no idea which one is correct. I can think of
at least four:
1. If /usr/obj is supposed to exist in a fresh install, it should be
added to the release.
2. If you are supposed to specify a -O or -M option to build.sh to
force the object directory to be created, the example should contain
such an option.
3. If you are supposed to manually mkdir /usr/obj, the example should
include that command.
4. If build.sh is supposed to create the object directory
automatically, it should be changed to do so.
