I am getting the following error in building qtsampleplayer:

Tried several options like giving path of libz.so in command line but no help

collect2: error: ld returned 1 exit status that means basically that something before went wrong.
/libz.so.1:error adding symbols:DSO missing from command linethat means that he is not finding DSO so you have not included correctly the libz.so BUT before it says: i386-linux-gnu/libQt5Gui.so.5.2.1:undefined reference to symbol 'inflateInit2_' So your problem is not in libz.so, it can be in libQt5Gui .
Do you really have both libraries where your project is looking? Seems the program is not finding them

I am trying to wrap QT UI in QT5 using a command
QT5_UI_WRAP (ui_forms/file.h ui_file.ui)
I have include QT5Widgets. Somehow this isn't working. Now everywhere I read, this is what needs to be done but there is always an error saying the .h file was not found. I have included the ui_forms folder in include path. Is there anything more that needs to be done with this. ? Am I missing something ?

You need to include the UIKit framework in your project and add #import <UIKit/UIKit.h> in your .xm file.
I am trying to compile qt with dbus but it gives me the following exception. I have installed the dbus version 1.3 in the system and I am using the following configure command.
Can someone point me as to what should be done.
configure -dbus -I/usr/include/dbus-1.0 -L/usr/local/dbus/lib -ldbus-1 -fast -prefix /home/thwijeth/Software/qt-4.8.1-com-debug -v
thank you in advance.

verify if /usr/include/dbus-1.0 contains a dbus directory, if it does not, verify whether /usr/include/dbus-1.0 contains dbus.h, if so you need to create a symbolic link to dbus-1.0 as dbus
ln -s dbus-1.0 /usr/include/dbus
and then try to rerun configure.
This solution worked fine for me for this missing header. However, I got then a different error fatal error: dbus/dbus-arch-deps.h: No such file. I worked around this error by copying this file from /usr/lib/x86_64-linux-gnu/dbus-1.0/include/dbus to /usr/include/dbus-1.0/dbus/. I don't know why this header was not in the /usr/include directory from the beginning. But this is my hack to the problem.

A simple Google search on "rpl_malloc" finds many references to this issue, with suggestions for solutions. The problem is that the Autoconf configure script is having trouble finding malloc for some reason, and tries to fall back to rpl_malloc. There are a couple of suggestions to work around this:
1.) Define the ac_cv_func_malloc_0_nonnull=yes environment variable before you run configure, for instance by running configure (assuming a bash shell) as:
ac_cv_func_malloc_0_nonnull=yes ./configure <your configure options>
or
2.) Manually change the configure script to comment out the rpl_malloc problem AC_FUNC_MALLOC line by prefixing it with a #.
