        Then keep that one and introduce one by one the elements of your other project until it either fails to build or build successfully

          For every element in the pro file, it does not fail if I put '#include <QGst/Init>' then I get the error 'QtCore/QtGlobal: No such file or directory' Then if I comment it back out, and run qmake, then build, I get no error. If I comment it out I get the error 'cannot find boost/config.hpp' until I run qmake again.

          I added 'C:\boost_1_58_0' to the include path, commented out '#include <QGst/Init>' ran qmake, and uncommented it, and it built with no error. Then I ran qmake again, and it game me the 'QtCore/QtGlobal' error again

            Ok… Then the silly question: do you have a QtGlobal file ? If so where is it ?

              Yes, I have 5 copies, they are in
              "C:\Qt\Qt5.4.1\5.4\android_armv5\include\QtCore\QtGlobal"
              "C:\Qt\Qt5.4.1\5.4\android_armv7\include\QtCore\QtGlobal"
              "C:\Qt\Qt5.4.1\5.4\android_x86\include\QtCore\QtGlobal"
              "C:\Qt\Qt5.4.1\5.4\mingw491_32\include\QtCore\QtGlobal"
              "C:\Qt\Qt5.4.1\5.4\Src\qtbase\include\QtCore\QtGlobal"

              Should I have a different one somewhere else? I am building with Mingw

                Did you modify your kits ?

                    I then added the pkgconfig and config then instead of '#include <QGst/Init>' I did '#include <QGst/init.h>' and I got back to the error of undefined reference to 'QGst::init

                      Check the output of pkg-config for QtGStreamer, compare it to the build output of your application. Check the -I lines to see if something is currently modifying them in the wrong way
