Note that you will not be able to build with 1.8.0 since we depend on
many features available only in nightly. You can see which nightly we
download by looking at the date in
https://github.com/servo/servo/blob/master/rust-nightly-date
(currently 2016-05-07). It may work with slightly newer or older
nightlies as well.
I suspect the reason you can't download the nightly is that the
platform detection code is returning "unknown" for your processor. You
might consider filing a bug for that. What target triple do you
normally use?
Is such download even available?
You can find the level of Rust support for various platforms documented
here:
https://doc.rust-lang.org/book/getting-started.html#platform-support
If you navigate to https://static.rust-lang.org/dist/2016-05-07/ (or
similarly for another date) you can find the official builds as well as
rustc-nightly-src.tar.gz, the source package that you can build yourself.
Back when I tried to build servo for ARM rust claimed ARM
compatibility but I could not find a prebuilt compiler.
rust-lang.org only started making builds of the standard library for
cross-compiling to ARM a few months ago, but it’s been functional (with
users building their compiler and standard library themselves) for
longer than that.
I downloaded the x86 version and kind of cross-compiled rust using
qemu and tweaked the servo build script to skip the download.
As Jack mentioned, you can copy servobuild.example to .servobuild and
configure it with the location of your Rust build. No need to tweak the
script.
The built servo was more flaky than the x86 one. iirc it seemed to
require more featureful graphics than fbdev. And i did not have the
exact nightly used by the build script, too.
Servo does do a lot of stuff of the GPU, but I don’t know the exact
requirements.
