I need to do a pull-request again for my fork, should be fixed if I start a pull request with:

@Fighter19 Which compiler ? Which Qt ?

@nemerle, it's the linker.

@hakusdream The linker is reporting the error, but the missing reference might be caused by bad compiler-qt version: Qt compiled for vs2013 used with vs2015

Mismatched header/binary.

Probably different versions of Qt, one which requires consistent types, the other did not.

It's just a template function that ensures types don't match for comparison and there is no implicit conversions happening, changing them to failing locations from ints to bools fixes the issue. (See earlier referenced commit)

@reductor See #62.

Rebase your commits, also.

Actually this problem occured on ArchLinux with the current up-to-date libraries.

[xxxxxx@XXXX lib]$ qmake -version
QMake version 3.0
Using Qt version 5.6.0 in /usr/lib

Disabling the test, I was able to compile the rest. Also some other tests successfully compile, but I didn't test further.

I'll try on Ubuntu though Travis-CI.
