np we all need a vacation. What I did was download QT because I wanted 5.6 and 5.7. The installer downloaded 5.6.2. I compiled against this download. I copied my compiled files to a FG folder to run and test. However I cheated and copied the QT files from the windows nightly build that I also downloaded. FG-Windows Nightly has 5.6.1 and I compiled against my QT download of 5.6.2 It kept crashing. The FG log file told me not to mix QT5.6.1 with 5.6.2. So this is my fault, and just wanted to warn people if you do specifically download the offline installer of 5.6 from the QT archive, you will get 5.6.2.
As an aside I did all this because I am also playing with OSG 3.5.x and it is not playing nice with QT.
First OSG 3.5.x - you lose access to the _linenumbers property, along with _coords in the CavasText module. (along with kerning that was "fixed" in a build previously)
Second, the new QT functionality added in June, QT/OSG 3.5.x needs a change if FG. All this is just me playing around. I have it compiling OSG 3.5.x and QT, however it crashes now - it used to work. QT 5.7 or 5.8 don't compile.
I have no expectations of anyone fixing this, just my own experimentation, and if anyone benefits from my findings, great. If not carry on.

I have had to download QT again and find that the 5.6 version is 5.6.2 not 5.6.1 as in the windows-nightly and 2013.2.x version of flightgear.
Just an FYI that you may need to update to 5.6.2. It compiles and works as far as a simple test is concerned.
I say this because I was setting up my own compiled version and used 5.6.2 and got an error in the log about mixing version 050602 and 050601
Ron, apologies, just catching up on emails after my holiday. Can you explain in (a lot!) more detail what you were doing to encounter this error? I ask because patch level version of Qt should be compatible. Im curious if you are mixing an official release from Jenkins with your own built files, and if so, why, and how?
