LOL, muggins created a ticket for changing the LLVM build, but forgot to
create one for rustc.
[https://www.rust-lang.org/en-US/other-installers.html#source] - at the
very bottom of the page, the first link is for Stable and labelled
'.tar.gz'. When I tried that a few days ago I got rustc-1.15.1.
Although configure still permits the
{{{
--disable-rustbuild
}}}
switch (fedora use that), it reports
{{{
WARNING: the makefile-based build system is deprecated in favor of
rustbuild
It is recommended you avoid passing --disable-rustbuild to get your
build working as the makefiles will be deleted on 2017-02-02.
}}}
So I suppose best not to do that.
Lots of configure options, and rustbuild downloads a binary from rust and
uses that to bootstrap the build. For the moment I'm using the shipped
LLVM.
I particularly wish to note two things:
First, the build defaults to silence (nothing until it completes or
fails), but
{{{
VERBOSE=1 make
}}}
provides output.
Second, it uses all cores, so trying to do timing with only 4 cores on a
well-endowed machine is probably not going to be possible. And adding
MAKEFLAGS such as
{{{
-j2 -O
}}}
either after 'make' or as
{{{
MAKEFLAGS='-j2 -O'
}}}
in front of make is both ineffective (still uses all 4 cores on my i3) AND
silences the build!
AFAICS, the cargo crates which this will enable are packages of metadata
to ensure a repeatable compile, so I _think_ this is still ultimately from
source.
