#310 fixed Debug build configuration looks for nonexistent libraries ataylor
Description

Switching a Qt4 project to debug mode with

CONFIG += debug console

causes build to fail with the error message

weakld: cannot open library file '<path>\QtGuid_s.a'

which is caused by the generated Makefile line

LIBS = -Le:\usr\lib -lQtGuid -lQtCored

A search both locally and using 'yum provides' indicates that no library named QtGuid?* exists anywhere.

Changing the above Makefile line to specify -lQtGui4 and -lQtCore4 allows build to complete, although presumably debug traces within the Qt4 runtime itself will not be possible.

#309 wontfix Provide i686 and pentium4 builds of Qt4 libraries ataylor
Description

Our Qt4 libraries at present are only available (at least on public repos) for the i386 architecture.

It would be good to have builds optimized for i686 and higher, hopefully able to take advantage of newer processor's capabilities (and possibly improving performance)?

For Qt4 apps, the performance of the runtime libraries is something of a bottleneck. Building them for newer architectures might be one way of helping with this issue.

#307 invalid qtconcurrentfilter.h generates -Wunused-local-typedefs warning when compiling with GCC 4.9.2 ataylor
Description

Compiling a Qt4 application with the current RPM/YUM GCC (4.9.2.1-3.oc00.i686) generates the following warning (often multiple times):

g++ -c @CXXFLAGS.qe.rsp @DEFINES.qe.rsp @INCPATH.qe.rsp -o mainwindow.obj mainwindow.cpp
In file included from e:\usr\include/QtCore/QtCore:124:0,
                 from e:\usr\include\QtGui/QtGui:3,
                 from mainwindow.cpp:23:
e:\usr\include/QtCore/qtconcurrentfilter.h: In function 'QtConcurrent::ThreadEngineStarter<void> QtConcurrent::filterInternal(Sequence&, KeepFunctor, T (C::*)(U))':
e:\usr\include/QtCore/qtconcurrentfilter.h:109:47: warning: typedef 'Iterator' locally defined but not used [-Wunused-local-typedefs]
     typedef typename Sequence::const_iterator Iterator;
                                               ^

This is quite inconvenient as certain IDEs or code editors (including mine) flag this as a problem and pop up a message during build.
