Request for 32bit travis build machine

Question

It seems that travis provisions a 64bit build machine by default when a integration process starts.

Is there any options that I can use in .travis.yml to request a 32bit Ubuntu build machine?

I really need 32bit OS, because the 64Bit Ubuntu refuse to install 32bit supporting libraries (ia32-libs).

The following packages have unmet dependencies:

ia32-libs : Depends: ia32-libs-multiarch

E: Unable to correct problems, you have held broken packages.

Answer 1

No, there is no such option (at least for now). See this issue: #986 travis_ci: Add 32-bit environments

@roidrage commented on 23 Jul 2015:

Closing this issue for now, as we have no immediate plans to add this feature.

Should we add it to the roadmap eventually, we'll make sure to update this ticket.

Answer 2

Travis supports a number of architectures using the arch: key. Unfortunately, none of these are 32-bit.

'shoogle' at https://github.com/travis-ci/travis-ci/issues/5770 suggests that it is possible to run a 32-bit image within a 64-bit container, by adding the following to .travis.yml:

services:
- docker
script:
- "docker run -i -v \"${PWD}:/MyProgram\" toopher/centos-i386:centos6 /bin/bash -c \"linux32 --32bit i386 /MyProgram/build.sh\""

And dlang suggest:

env:
 - ARCH="x86_64"
matrix:
  include:
    - {os: linux, d: dmd-2.071.0, env: ARCH="x86", addons: {apt: {packages: [[gcc-multilib]]}}}
    - {os: linux, d: ldc-1.0.0, env: ARCH="x86", addons: {apt: {packages: [[gcc-multilib]]}}}
script:
 - dub test --arch "$ARCH"
