I just updated the sources, compiled tip in /home/lucio/Project/go, then
elsewhere checked out "-b go1.10.1".
It is usually me being distracted, but I tried both
GOROOT_BOOTSTRAP=/usr/local/go1.9 ./all.bash
and
export GOROOT_BOOTSTRAP=/usr/local/go1.9
./all.bash
yet the build reported using /home/lucio/Project/go to bootstrap.
I have verified that there is NO "bin/" directory in /usr/local/go1.9,
which may be diagnostic here: it is very helpful but surprising to find
that "go build" uses the default GOROOT in place of an inappropriate
GOROOT_BOOTSTRAP. I think at least a warning should be issued.
That explains why TIP was built correctly using the 1.4 version, as
expected.
In fact, here, lightly edited to remove embarrassing typos is the start of
the typescript:
