Need Help: (QT 4.8.5 and Mavericks 10.9.4) ld: symbol(s) not found for architecture i386

Hello,
I am having a hard time with an error I got running make and I think it may be a problem with QT.
Before the error:

@The error seems to be coming from something I am missing or doing wrong with QT. I am not experienced in building so I really appreciate any help I can get on this since this error is standing in the way of completing my project.
I am using QT 4.8.5 and Mavericks 10.9.4 and am trying to build an open source project called qcad.
Thanks everyone

Hi and welcome to devnet,
First thing and most important, 4.8.6 is currently the only official Qt 4 series version that supports Mavericks.
Also, it looks like you are trying to build your project for 32bit, is that really what you want ?
-
Thank you for your reply SGaist. Perhaps I should try it over with 4.8.6 since that supports Mavericks.
I don't want to build in 32bit I think because I have a brand new macbook pro so it is probably 64bit. How do I build in 32bit? Do I need to try it over again with QT 4.8.6 or can I do a quick fix to 64bit and try again?
-
Even if your MacBook was a bit older, the last version of OS X running on 32bit processor is Snow Leopard which is quiet old by current standard.
Just build your project for 64 bit
-
By default Qt is built in 64bit so there should be nothing special to be done. Are you trying to build an external project ?
-
I am trying to modify an open source 2D drawing program called QCAD. I looked on the internet and saw that I need to configure Qt so that it knows to build in 64 bit. Here are the directions for building QCAD: http://www.qcad.org/en/component/content/article/78-qcad/111-qcad-compilation-from-sources
I am trying to reconfigure Qt like this: cd qt-everywhere-opensource-src-4.8.5
./configure -fast -opensource -arch x86_64 -release \
-no-qt3support -qt-zlib -qt-libtiff -qt-libpng -qt-libmng \
-qt-libjpeg -confirm-license
and make to see if it works this way. If you see anything wrong with this or if I should use a different version of Qt then please let me know.
Thanks
-
There's no need for the arch switch. Again, use 4.8.6 since you build from source anyway. You could also download the pre-built package.
By the way, which version of Xcode are you using ?
-
Hello SGaist, I did start using 4.8.6 a few hours ago and it got through the error so thank you for suggesting that earlier. However I got a new error which is shown below:
@Undefined symbols for architecture x86_64:

@I haven't heard of phonon (outside of my undergrad physics classes), do you know what it is and how to solve it? Thanks again for your help.
My Xcode is Version 6.0.1
-
Are you sure it wasn't about photons ? ;)
Phonon is the multimedia backend used by Qt 4 however I doubt that QCAD makes use of it.
This error generally appears when QObject wasn't properly moc'ed, did you start from a clean build ?
On a side note, if you don't need phonon, you can also simply disable it for the time being to go forward.
-
SGaist, how do you disable Phonon from the build? Do I have to leave out something in the configure command? This is what I used to configure:
@cd qt-everywhere-opensource-src-4.8.6
./configure -fast -opensource -arch x86_64 -release
-no-qt3support -qt-zlib -qt-libtiff -qt-libpng -qt-libmng
-qt-libjpeg -confirm-license@Thanks again for your help. Also, I was talking about "these phonons":http://en.wikipedia.org/wiki/Phonon
-
Yes, just add -no-phonon don't forget to do a make confclean before restarting configure.
If you want to simplify a bit things, you can do an out of source build, so if something goes wrong you can simply nuke the folder content and start over.
Thanks for the link, I learned something new :)
