Maybe it could be QWT (and QWT-Polar) which are linked against Qt4? You will probably have to recompile such dependencies as well.<span class=""><br>

Hi Dave<br>
<br>
there is still Qt 4 involved (partially?) as the 4 in the end of<br>
this line indicates:<br>
<br>

<br>
Did you clean the build directory after the build attempts for master?<br>
<br>
<br>
I just did a complete clean build just to be sure and it had the same<br>
crash. The same crash happened. Here's the output from ldd grepped for qt:<br>

<br>
So it looks like you already pointed out that the Qt4 libraries are<br>
being linked in as well for some reason. Any ideas on what I should do<br>
to run down where this issue is coming from?<br>
<br>
For your other question (lrelease-qt5) you can revert this commit:<br></div></div>

<br>
I guess I'll have to figure out another approach to handle this<br>
suffix than just deleting it like this commit does.<br>
<br>
<br>
I reverted that commit and it built without me specifying the path to<br>
lrelease-qt5.<br>
