Travis CI for a Qt5 project

Question

I am trying to use Travis CI with a Qt5 project, but I can't get the build to pass.

My .travis.yml

install:
  - sudo apt-get update
  - sudo apt-get install qt5-default qttools5-dev-tools

script:
  - qmake -project
  - qmake Ultron.pro
  - make

Last segment of the error log:

0.58s$ sudo apt-get install qt5-default qttools5-dev-tools
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package qt5-default
E: Unable to locate package qttools5-dev-tools
The command "sudo apt-get install qt5-default qttools5-dev-tools" failed and exited with 100 during .
Your build has been stopped.

Does this have something to do with it not being an official package?

Answer 1

You need to add the correct repository and update apt:

sudo add-apt-repository --yes ppa:ubuntu-sdk-team/ppa
sudo apt-get update -qq

Your .travis.yml will then look like:

before_install:
 - sudo add-apt-repository --yes ppa:ubuntu-sdk-team/ppa
 - sudo apt-get update -qq
 - sudo apt-get install qtbase5-dev qtdeclarative5-dev libqt5webkit5-dev libsqlite3-dev
 - sudo apt-get install qt5-default qttools5-dev-tools

script:
 - qmake -project
 - qmake Ultron.pro
 - make
