GLib-CRITICAL and GLib-GObject-CRITICAL errors when unit testing.

[SingingBush]

I am working on an app that depends on gtk-d 3.1.4 and uses dunit for testing. When running dub test on travis-ci.org I'm getting the following errors in the logs:

Do you have some code i could try? I'm currently not running into any problems running unittests.

[SingingBush]

The code that I'm working on is dfract. When I run dub test on my machine (Fedora 22) it runs fine, it's just on travis (Ubuntu 12.04 LTS) that I get the problem.

[MikeWey]

The problem is that the D runtime runs the unittests before calling main, while the GTK/GObject runtime is initialized there. This means that when running unittests on code using GtkD you are calling GTK/GObject functions without initializing there runtime. Now with newer versions of GObject >= 2.36 the type system is initialized automatically, and the error above isn't triggered, although other errors might occur when testing different parts of GtkD/GTK.

For this error you could try calling gobject.Type.Type.init() at the start of the unittest.

thanks for the info. after some communication with the guys at travis-ci I've got my build working again. They've finally got Ubuntu 14.04 build agents (as well as mac osx) so the available dependencies are a lot more up to date.

in case you're interested, the following travis.yml is what I am now using:

language: d

sudo: required

services:
 - docker

before_install:
 - "if [ ${TRAVIS_OS_NAME} = 'linux' ]; then sudo apt-get update -qq; fi"
 - "if [ ${TRAVIS_OS_NAME} = 'linux' ]; then sudo apt-get install -y libcairo2-dev libgdk-pixbuf2.0-dev libgtk-3-0; fi"
 - "if [ ${TRAVIS_OS_NAME} = 'osx' ]; then brew update; fi"
 - "if [ ${TRAVIS_OS_NAME} = 'osx' ]; then brew install glib cairo pango gtk+3; fi"
