Help with QtGStreamer undefined reference to QGST::init
-
TEMPLATE and TARGET should be used with = . They contain only one value.
Do you still have that error if you don't use pkgconfig ?

Then create a default widget project and see if you can built it

@SGaist Hi, I built an blank widget project, and I build one of the examples from Qt, and it worked fine
-
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 ?

No, I even just got done uninstalling and reinstalling Qt 5.4.1 and QtCreator 3.3.2 and I just got the same QtCore error

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
