    @jsulm Since I'm on Windows, it should still be -llibzmq-v140-mt-s-4_3_4. However for this library to work, a preprocessor directive ZMQ_STATIC needs to be added

    I solved it, the makefile contains this command as well: flex MyLanguage.l and in the OS there is two intalled flex, Qt used the wrong one.

    Hi, Might be a silly question but are you linking your .dll against Qt's widgets module ?

    @JonB well, I thought it just creates a new build file for the new compiler (which it does), but I have to admit my understanding for compilers is not very deep.

    Just use QT += module That test is really only useful for code bases that should be built with both Qt 4 and Qt 5 since the widgets have moved to their own module in Qt 5.

    For b, check whether the library has other dependencies. You might be missing one.

    As far as I understand qmake should take care of it automatically right? It generates a makefile for dummyimplugin3 makefile.debug which has .moc\moc_dummyinputmethod3.cpp listed under SOURCES and .obj\moc_dummyinputmethod3.obj listed under OBJECTS From the compiler output it seems it gets built and linked?: cd dummyimplugin3\ && ( if not exist Makefile C:\Qt\5.5\msvc2013\bin\qmake.exe C:\QtProjects\MaliitFrameworkGitHub\framework\tests\dummyimplugin3\dummyimplugin3.pro

    The above problem has been "autoresolved" with a reboot of my PC. Another problem arised: "LINK : fatal error LNK1104: cannot open file 'qtmaind.lib'" This is due to the fact that release libraries and debug libraries are stored into 2 different folders. So I've taken the source files of Qt4.8.4 from OSG and recompiled them with the desidered options. Now everything works.
