Problem with qt-mac-opensource-src-4.4.0-snapshot-20080101
Message 1 in thread
I am trying to check out QPrinter::setPaperSize ( QSizeF, Unit ) but
I am having trouble if I compile with XCode.
It tells me:
/usr/bin/ld: Undefined symbols:
QPrinter::setPaperSize(QSizeF const&, QPrinter::Unit)
However, if I compile with the macx-g++ spec, I get a clean build.
Should I submit a bug report ?

QPrinter::setPaperSize() has been introduced in Qt 4.4.
Is some other version of Qt 4 installed on your system? For some reason you
must be linking to that version of Qt 4 instead of the Qt 4.4 snapshot.

I kinda doubt it.
Here is the tail end of both compiles -- the bold/underlines are mine
to point out the library reference.
BTW, g++ is a link to g++-4.0. That was the FIRST thing I checked.
With XCode:

But is there no other version of Qt installed on the system?
This really looks strange: if linking to the same library, I don't understand
how the symbol is found in the second case, but not in the in the first case.

Yes, there are other Qt installations on the system, but in different
directories.
I was assured repeatedly (Look for a thread - Subject: Multiple
development environments: How To on Mac and Windows ?) that
everything depended on what version of qmake is used
Nothing more.
QTDIR makes no difference - Qt 4 ignores it.
Is that the case ?
Any suggestions ?
In the meantime, I am compiling the latest snapshot to see if it
makes any difference.

Then maybe one of these Qt libraries is installed in a directory searched by
the linker by default, or in a directory pointed to by a linker "-L" option in
the XCode case. For example:
/Users/igor/Desktop/DIY-Templates/Qt/DIY/current/DIY_Notes/v1.1i/DIY_Notes-beta-pageSize/build/Default

It probably won't.

And on other volumes, for example in /Users or /Developer?

There was (emphasis on past tense) one in /Developer (from Qt 4.3.dmg) but I removed it.
Things work now
That was probably it.

Good, I'm happy the problem is solved. Most probably the library had been
pulled in by this compiler option:
-L/Developer/SDKs/MacOSX10.4u.sdk/System/Library/Frameworks
I'm not sure why this compiler option appears in the XCode case and not in the
plain g++ case - I don't know much about Mac OS.
This looks like an issue with the .dmg package you were using, which somehow
configured XCode to use that directory and/or put Qt 4.3 in that directory.
Where did you get the .dmg package from?

The dmg in question is one of the official ones.
I got it from trolltech,com or one of the official mirrors
I found that by building the different versions with the "-prefix-install" option isolates them nicely to allow for multiples.
Additionally, a static build fits on a single CD-ROM (between 400-500Mb), while I have to use a DVD-R for a shared build (just under 2Gb). By making the path to the build on the CD the same as to the hard drive it builds on, I can develop from the CD/DVD and easily swap versions.
Is there a target date for 4.4 ?
