Travis CI Update: Trusty as default Linux is coming

FYI: https://blog.travis-ci.com/2017-07-11-trusty-as-default-linux-is-coming

We currently still use Precise to build OSVM on Linux.

I hope migrating to Trusty won't cause any problems for us...

I assume that the move to a newer OS will mean testing with a newer
version of gcc (4.6.3 seems to be the current default).

The good news is that a few people have tested building the VM with gcc
4.8.x (4.8.5 in my case).

However moving to Trusty also means that when Ubuntu 18.04 is released
in less than a year it will most likely be difficult for anyone
upgrading to get access to gcc 4.8.5, since 5.4 is the release used in
16.04.

Would it be possible to move straight to Xenial (16.04)?

Thanks,
Alistair

Why would anyone still need access to gcc 4.8.5? The binaries should work

on 14.04+ and hopefully also on 12.04, right?

Travis does not support Xenial yet, but they are working on it [1].

Does the OSVM compile with gcc 5.4?

Best,

Fabio

Just to mention that compiling with clang might also be an option.

MacOS 32 & 64 + Win64 are already clang-based.

My understanding is that gcc 4.8(.4) is the default version in trusty,
so if anyone else wants to build the VM with the same compiler, they'll
need gcc 4.8.

At the moment it is needed because a few people have found that the VM
doesn't work properly if compiled with gcc 5.4.

I hope so, although if it doesn't work on 12.04 I think we can live with
that.

OK, I guess that limits things.

Yes, but it has problems, see:
