Cannot run executable with Travis-CI - Not sure what I am doing wrong

Question

I have been trying to figure out how to make Travis-CI build a QT5-only app.

I has to be Qt5, and include the QSerialPort module, so the stock Ubuntu version is not available (Missing QSerialPort). I installed Qt 5.x onto a 12.04 Ubuntu VM, tar'd up the files into something I placed into another repo, but when I download and extract the Qt5 executables (qmake + sources, etc), I cannot run them, even though qmake is found in the $PATH.

The code is all posted on https://github.com/npotts/QuteSerial.

.travis.yml

language: cpp
compiler:
  - gcc

before_install:
  - wget https://github.com/npotts/Qt5-Travis-CI/raw/master/Qt5.txz
  - tar xfp Qt5.txz -C ${HOME}

install:
  - sudo apt-get update -q
  - sudo apt-get install build-essential

script:
  - export PATH="${HOME}/Qt5.3.2/bin:${PATH}"
  - which qmake
  - uname -a
  - qmake --version
  - pwd
  - ls *
  - ls -alh ${HOME}/Qt5.3.2/*
  - ../../Qt5.3.2/bin/qmake
  - vendor/../../Qt5.3.2/bin/qmake
  - make -j$(nproc)

Answer 1

It's not pretty, but this before_install script is what I use to install Qt5 on Travis CI from the Ubuntu repositories.

It's important that the apt-get commands are used as is; dependencies don't resolve correctly so I am manually fixing them.

before_install:
- sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu trusty universe"
- sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu trusty main"
- sudo apt-get install debian-keyring debian-archive-keyring
- sudo apt-key update
- sudo apt-get update
- sudo apt-get install qt5-default qt5-qmake qtbase5-dev-tools qtchooser qttools5-dev qtbase5-dev libgles2-mesa-dev libqt5gui5 libqt5serialport5-dev libqt5printsupport5 libqt5widgets5 libgles2-mesa libgl1-mesa-dev libgl1-mesa-glx libglapi-mesa libegl1-mesa-dev libpango-1.0-0
- sudo apt-get install zlib1g-dev libudev-dev
