Qt 4.7.0 Building Problem on Mac OS Snow Leopard

legume55

I have the same problem. New machine, new installation, same message.

ASGR

If you're building your project from the command line then you
need to set the environmental variables in either the global profile
file (located in /etc/profile) or the user .profile file (located in the users
home directory that is usually hidden, type 'ls -la' to show hidden files).

The PATH environmental variable only tells the terminal where to
find other binary executables and should include the path to the
QT binaries.

To find the libraries, I use the gcc environmental variable
LIBRARY_PATH set to all the locations where I've installed
libraries but I've also seen used LD_LIBRARY_PATH and
DYLD_LIBRARY_PATH to find libraries.

Hope this has helped.

Same problem. I compile a new project with QtCreator 2.0.1 / Qt 4.7.0 under Snow Leopard. I did not have this warning with QtCreator 2.0.0 / Qt 4.6.2.

Hi,

I "installed" Qt 4.7 SDK.mpkg bundle on snow 10.6.4 mac/ g++ gcc version 4.2.1.
I can run executables in Qt creator from other libraries, but when I am trying to install a light
viewer built on Qt I get 2 linker warnings by qmake, i.e.

ld: warning: directory '/tmp/qt-stuff-6474/source/qt-everywhere-opensource-src-4.7.0/lib' following -L not found

ld: warning: directory '/tmp/qt-stuff-6474/source/qt-everywhere-opensource-src-4.7.0/lib' following -F not found

With qmake -query everything seems to be right, but qt installation seems broken.
qmake is there, but the lin dir in
/tmp/qt-stuff-6474/source/qt-everywhere-opensource-src-4.7.0/lib
has been removed.

This seems like a bug to me (installing a lib in /tmp -> in a directory that is cleaned every time I reboot the machine??) 'n I have already filed it. Let me know if you have any hints,

cheers

For workaround please have a look at "QTBUG-13462":http://bugreports.qt.nokia.com/browse/QTBUG-13462

Con was right. I had another Qt installed via MacPorts that I've now uninstalled.
But I left earlier versions of Qt that were installed via MacPorts as a dependency for another ports,
ex. boost, cgal (libs rather complicated to build by source), since I don't want to destroy the dependencies. Do you think that this might cause the linker warnings above? I installed a Qt 4.7 SDK.mpkg bundle again, I executed the scripts at the bottom of http://bugreports.qt.nokia.com/browse/QTBUG-13462 , but I get the same warnings..

cheers

... Since I can create the applications I want, I do not worry anymore about the ld warnings.
Anyhow, please drop a notification if you fix this.

cheers

@N you should update to Qt 4.7.1 which fixes this issue along with others.

I am running 4.7.1, and I still have this problem. Any suggestions?

Running on a Mac.

This looks like a bug in qmake. It is used to build the Makefile for the project (you can find the -L option in the Makefile produced).

Looking at the qmake binary with:

% strings /usr/bin/qmake | grep qt-everywhere

produces lots of strings that begin with:

/tmp/qt-stuff-6474/source/qt-everywhere-opensource-src-4.7.0

If you want you could hand-edit the Makefile to remove this option from the link command. Alternatively:

% sudo mkdir -p /tmp/qt-stuff-6474/source/qt-everywhere-opensource-src-4.7.0/lib

will create the directory and silence the warning.
