I was curious to see some output from different compilers and version so I set up a code integration test on my 0ad GitHub fork.
Can anyone see why the build is failing at glooxwrapper.cpp?
As far as I can tell, I've installed all the required dependencies. The first 3 jobs shown here are running on trusty, using gcc-4.8, 7.0, and clang 5.0. Each one fails at the gloox build:
