What I am not able to understand is what its looking for. Is it looking for a dll or \
a .lib file? If it says its not able to find the method QString::toUtf8, is it not \
able to find QtCore.lib? The LIBS parameter for the linker is this:

/LIBPATH:
C:\Users\cgopalan\pyqtdeploy1\sysroot-win\lib\python3.4\site-packages\PyQt5
C:\Users\cgopalan\pyqtdeploy1\sysroot-win\lib\python3.4\site-packages\PyQt5\QtGui.lib
C:\Users\cgopalan\pyqtdeploy1\sysroot-win\lib\python3.4\site-packages\PyQt5\QtCore.lib
 C:\Users\cgopalan\pyqtdeploy1\sysroot-win\lib\python3.4\site-packages\PyQt5\QtWidgets.lib
 C:\Users\cgopalan\pyqtdeploy1\sysroot-win\lib\python3.4\site-packages\PyQt5\Qt.lib
/LIBPATH:
C:\Users\cgopalan\pyqtdeploy1\sysroot-win\lib
C:\Users\cgopalan\pyqtdeploy1\sysroot-win\lib\python34.lib
/LIBPATH:
C:\Users\cgopalan\pyqtdeploy1\sysroot-win\lib\python3.4\site-packages
C:\Users\cgopalan\pyqtdeploy1\sysroot-win\lib\python3.4\site-packages\sip.lib
advapi32.lib shell32.lib user32.lib ws2_32.lib ole32.lib oleaut32.lib
/LIBPATH:
C:\Qt\5.5\msvc2013\lib
C:\Qt\5.5\msvc2013\lib\Qt5Widgets.lib
C:\Qt\5.5\msvc2013\lib\Qt5Gui.lib
C:\Qt\5.5\msvc2013\lib\Qt5Core.lib 

All these files exist. So I am not sure what the linker error means.

Thanks
Chandrakant

qmake knows where the Qt libraries are installed. If the qmake generated Makefile \
can't find them then that implies there is something wrong with your Qt installation.

There is nothing special about SYSROOT, it is just a covenient way of keeping all \
platform specific things together.
