      Hi i have used QtCreator for developing application. Now that application is running on my host machine. Now i want to use QtCreator to cross compile the developed application. Is there any procedure to cross compile in QtCreator.

        First thing to do is cross-compile Qt, then add that new build to the known Qt Versions of Qt Creator, make a kit with it and use it

          Cross compiling the Qt is through command prompt only?

          Assume that i have cross compiled Qt through terminal. My next question is how to add that new build to QtCreator?

            Yes it is.

            Qt Creator -> Preferences -> Build & Run -> Qt Versions

              Hi SGalst,

              I have cross compiled my Qt open source 4.8.5 and build the Qmake with ./configure options......

              Now i want to give this Qmake path to the Qtcreator......through Tools->options->Qt4 and add....

              now when i add its showing some danger symbol and telling Qmake link broken.....

              i am using QtCreator 2.3.2......

              Initially i thought may be using old QtCreator.......then i added this Qmake which i made with Qt4.8.5 in the Qt creator based on the Qt 5.2 even then i am getting error saying that No compiler can compile this Qmake..

              Please help me...

                First thing to do is update your Qt Creator to at least 3.0.0 otherwise your won't be able to use Qt 5.2

                  Hi SGalst,

                  i have changed all the versions following versions am using.

                  I am using Qt source libraries from 4.8.4

                  and Qt creator am using is 2.7.2 which is based on Qt4.8.4....i think there wont be any issue with this right?

                  I just want to update further:

                  I successfully configured the libraries with the following configurations.

                  export PATH=$PATH:/home/anoop/Desktop/arm-2011.03/bin
                  arm-2011.03/bin: These binaries downloaded from CodeSourcery (Mentor Graphics) site.

                  ./configure -qpa -arch arm -xplatform /home/anoop/Desktop/qt-everywhere-opensource-src-4.8.4/mkspecs/qws/linux-arm-gnueabi-g++ -no-largefile -no-accessibility -verbose -little-endian -no-webkit -prefix /home/anoop/Desktop/ARMBuildQt -no-qt3support

                  afterwards i did make and make install.

                  Now my build Qt libraries are there in ARMBuildQt folder.

                  I have opened QtCreator 2.7.2 and given Qmake path for Manual Qtversion

                  Now it says there is no compiler to compile, Now i have added compiler as arm-linux-gnueabi-g++

                  after all this it saying configure the tool kit....i dont know what to fill in that toolkit option...

                  Please help me i am really stuck at this point.
