Another installment in the [saga of cross-platform CI](https://discourse.julialang.org/t/julia-is-now-available-on-travis-windows-builds/27187)! Just like for Windows, Julia Linux jobs on Travis CI can now use `arch: x86` to test with a 32-bit (i686) build of Julia.
Users of [Appveyor.jl](https://github.com/JuliaCI/Appveyor.jl) are likely already familiar with testing both 32- and 64-bit Julia builds on Windows using the `x86` and `x64` platform specifications. Previously this was only convenient way to test Julia packages on a 32-bit Julia build, and Appveyor.jl is only set up for Windows jobs.
You may be asking yourself, “Why should I care about 32-bit systems?” Ensuring your code works on 32-bit systems (assuming it’s designed to be) betters the experience for users who run 32-bit systems, but it also helps catch memory issues and implicit assumptions about the underlying system. For complex software this can be especially worthwhile.
Unfortunately, Travis does not currently use `arch` as an array for generating a build matrix, which means that testing with multiple architectures is a bit verbose. For example,
```yaml
matrix:
include:
- os: linux
arch: x64
julia: 1.0
- os: linux
arch: x86
julia: 1.0
```
See [this comment](https://discourse.julialang.org/t/julia-is-now-available-on-travis-windows-builds/27187/18) on the Windows post for more discussion on this. Hopefully this will be simplified in the future.
A special thanks to Hiro Asari (BanzaiMan) from Travis for working with us on this.
Enjoy your build!

Just being curious, are there still 32-bit i686 systems in production use? AFAIK the last one was manufactured more than a decade ago.

Some raspberry pis are 32 bit… (I know nothing about hardware architecture, I just remember a bunch of code I’d written with `Float64` failed when I tried to run it on my pi)

But they aren’t i686.

Hence my disclaimer 😂. I don’t have any sense of why that matters (not asking you to explain, was just assuming this was for testing platform-agnostic 32 bit code)

Depends on one’s definition of system, but e.g. the Quark series of micro-controllers from Intel use an x86 CPU and are still being manufactured and available to OEMs (though they were recently discontinued on the general market). In terms of normal PC-based systems though, it’s been a while - the Lincroft Atom line released in 2010/2011 is among the most recent.

I added an issue in PkgTemplate ([https://github.com/invenia/PkgTemplates.jl/issues/87](https://github.com/invenia/PkgTemplates.jl/issues/87)), so we add the latest changes to the package creation template.
