Compilers from.. debian?

Compilers from.. debian?

[Matt Hart]

Hi all,

Does anyone have a strong opinion about where we get our compiler releases from?

Currently it's a mash up of Linaro for ARM(32/64), MIPS from unknown,
and X86 from whatever ubuntu is installed on the builder

As part of my work to start building with multiple compiler versions,
I've been creating Dockerfiles for the builders with different
compiler versions installed in them. As I've been doing this, it's
been really easy to just install the various compilers packages from
Debian. They also cover a lot of architectures we're hoping to add in
the future.

Anyone mind if we start using Debian toolchain releases in future?
I'm no toolchain expert, so I'm looking for some opinions.

Thanks!

I think the current tarball way is a hack and not scalable, so...

It's better than what we're doing today, and has a much clearer
upgrade/migration path, so I say go for it!

The only concern I can think of is that it's going to be a bit harder for
those not fortunate enough to run Debian to get the toolchains if there's
some reason to reproduce things. On the other hand that's a rare occurrence
and with moving the builders more to Docker there's always the option of
using the container to get the compilers on other OSs.

I've been thinking about adding a section to the build page of "repeat
this build" and a link to either a dockerfile or image which runs the
identical steps in the same environment, it could be a really nice
feature to add.

That'd be a neat thing to have!

+1 and thank you for taking care of this.
