Mac/Qt 4.3/Xcode - undefined symbols - QString::fromAscii_helper
Message 1 in thread
Hello folks,
First off, I'm new to this list and I'm looking forward to useful
discussions on this list. :)
Today I downloaded and compiled Qt 4.3 (open source edition) on my
MacBook running Mac OS X 10.4.10. Qt compiles fine and everything
looks normal to the point where I want to compile a little test app I
wrote.
I took the chat example that comes with Qt to see if the problem is
specific to my code/project. The chat example causes the same problem.
I used qmake -spec macx-xcode to create a Xcode project file, which
allows me to compile/debug and run my code in Apple's IDE.
Compiling from console by using qmake and make works fine. The app
builds and runs.
An attempt to compile the very same code from Xcode brings up the following:

Has someone seen this or something similar before? Any help would be
highly appreciated. :)

I can't find any indication in the command shown, that the linking
command include
the directory containing the Qt frameworks in the framework search
paths:
-F/usr/local/Trolltech/Qt-4.3.0/lib
This indicates an error in your qmake project file.

An astronomer to a colleague:

do. Not only is it a filthy habit, but it must cost a lot of money too.
-Thats no problem. I've got a big government grant for the study of

Hello again,
this is weird because "qmake" and "make" compile and link the app just
fine. I'd guess that the .xcodeproj file that is generated by "qmake
-spec macx-xcode" is probably buggy and does not contain a needed
configuration parameter.
I'll look into this and see if I can solve this by myself. Any tips or
hints would be helpful, though. :)

After installation, do you change the .profile and give in the PATH
variable?

It looks like I found the problem to this whole error thing.
The fact is that the linker is called differently from Xcode compared
to make. After some experimenting I went into Xcode's target settings
and removed "/usr/local/Trolltech/Qt-4.3.1/lib" from 'Library Search
Paths', then put that into 'Framework Search Paths'.
It seems as if there is a bug in the latest qmake spec for Qt 4.3.0
and 4.3.1 that causes this to get messed up. I opened a few older
.xcodeproj files and those have the search path settings filled out
correctly.
Is this a bug or something I have set up incorrectly?
Thanks in advance!
PS: When I compare the two mkspecs for Qt 4.2 and Qt 4.3 I see lots of
changes. I guess something went wrong at Trolltech when someone
updated the specfile...
