<div>OK thanks, exactly the general guidance I was looking for.
I'll look into upgrading. Is there currently a version that
makes things easiest?</div>

<p>Building recent QGIS versions on 20.04 is going to be
quite a lot of pain since you'll need indeed to have a qt
5.15 build, and all the other auxiliary QT based
dependencies build against it.<br>
</p>
<p>I'd suggest you update to 22.04 at least. Or if you don't
want to do development but can live with released
versions, try conda-forge builds (cf <a

<div>Hi all,</div>
<div><br>
</div>
<div>while working on compiling qgis on ubuntu using
these instructions [0] , i've run into an error while
running cmake that "QRecursiveMutex" is not found. <br>
</div>
<div><br>
</div>
<div>It looks like that became available in QT 5.14. <br>
</div>
<div><br>
</div>
<div>Ubuntu 20.04 installs QT 5.12. During my searches
i've seen comments that imply 5.15 might not be
available for 20.04. I'm trying to figure out whether
I should be trying to upgrade Qt, if I have to upgrade
Ubuntu, or if there is some option in the compilation
process that can resolve this for me. <br>
</div>
<div><br>
</div>
<div>I've installed Qt 5.15.2 to /opt/ and added it to
PATH, but qtdiag still indicates i'm using 5.12.x<br>
</div>
<div><br>
</div>
<div>I thought i'd start by asking here before asking on
a Qt general forum in case there's a qgis specific
solution.</div>
<div><br>
</div>
<div>I've also set the cmake 3d option to "no" which got
me around the absence of q qt 3d extras pacakge/file.
So maybe there's a similar solution for this although
this version problem seem more essential. <br>
</div>
<div><br>
</div>
<div>Thanks for any suggestions!<br>
