Ian has been trying to build my qt5-mac-devel port for Qt 5.4.0. If I understand correctly he runs 10.7 and seems to be using the system clang compiler.<br>
<br>
The build halts with an error that neither he nor I can make sense of - how can a ctor be deleted?<br>

Can anyone here make sense of the error and indicate how to avoid it, or should I ask this on a Qt ML?<br>
<br>
AFAIK Qt 5.4.0 *can* be built on 10.7 and I presume that means with the system clang, but doing so may require special precautions that my port does not currently take.<br>
<br>
@Jeremy W: you're running 10.7 too, no?<br></blockquote><div><br></div><div>Yes, I have a macbook running 10.7 currently. I used the system clang to build Qt 5.4, though I didn't download and apply all the patches you have in your macports trac ticket. I only cloned Qt5 5.4 branch, added the QSP patch and built it fine here. I built it outside of the source tree in a qt5build folder. I built it twice actually, once with -developer-build and once without (to install it into /usr/local/Qt-5.4.2 so I can build qtspeech against it). Does one of the patches on the trac ticket change QBasicAtomiciInt in any way? </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
@Ian: if you feel like perusing Qt's building documentation for clues, by all means do so, if not, please put this on hold until we figure it out. I sadly don't have access to a 10.7 machine so cannot test things directly.<br>
