      I'm using the following guide to install QT on the raspberry Pi 2:

      https://wiki.qt.io/Native_Build_of_Qt5_on_a_Raspberry_Pi

      I have successfully run the configure and make commands with no errors. I am now trying to run make install but this fails giving the following error:

      /usr/bin/ld.gold: error: cannot find -lpoly2tri
      collect2: error: ld returned 1 exit status
      Makefile:272: recipe for target '../../../qml/QtLocation/libdeclarative_location.so' failed
      make[4]: *** [../../../qml/QtLocation/libdeclarative_location.so] Error 1
      make[4]: Leaving directory '/home/pi/opt/qt5/qtlocation/src/imports/location'

      Makefile:549: recipe for target 'module-qtlocation-install_subtargets' failed
      make: *** [module-qtlocation-install_subtargets] Error 2

      Any suggestions/advice on how to proceed is appreciated, thanks!

        It seems a new dependency has been added called poly2tri (library)
        https://code.google.com/p/poly2tri/ (check if your distribution provides poly2tri and install the development files)

        Compile/install the library should do the trick, hopefully.

          I wasn't able to find development files for the raspbian distribution that I am using for poly2tri.

          I notice in the lib folder that the code should be searching in that there is a relevant poly2tri library file:
          /home/pi/opt/qt5/qtlocation/lib/libpoly2tri.prl

          Is there some way of making the code see this library?
          I notice that this similar issue has been seen in the past:

          https://bugreports.qt.io/browse/QTBUG-43006

          Is there some other way of solving this?

            In the bug ticket: "Fix Version/s: 5.4.1"
            Which Qt version are you trying to install?

                Were you able to solve this issue? I ran into the same problem on a Virtual Machine with Ubuntu Server 14.04
