[PyQt] Linker errors - seems like its not recognizing QtCore and QtGui?

[Chandrakant Gopalan]

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

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.
