    first you need to add the following line to your .pro file
    @CONFIG += static@

    And also note that you need to rerun qmake everytime you alter the .pro file.

      Thx for your answer.

      i added the CONFIG+=static in the project settings in additional arguments, but i can do it in the Pro file again.
      I saw that the #include<QCoreApplication> refers to my standart qt under c: Qt5.2/...
      how can i change this?

      This is my error:

        check your qt creator settings.
        Or if you use the command prompt make sure your environment variables are pointing to correct qt installation.

          which settings can i check? the environment variables are ok and i get the same error in command prompt as in qt creator.

          i noticed that the include< offers files depending on the projectpath, but there is no Q... as proposal

            QTDIR, etc.
            just check all of them to make sure ;)

              They seem to be ok. No path to the old(normal) qt-version.

              Maybe i built qt wrong?
              here is my command:
              C:\qt-everywhere-opensource-src-5.2.0_14Versuch\qtbase>configure -embedded -platform win32-g++ -xplatform linux-arm-gnueabi-g++ -no-angle -opengl desktop -static -opensource -nomake examples

              @
              qmake.conf:

              qmake configuration for building with arm-linux-gnueabi-g++

              MAKEFILE_GENERATOR = UNIX
              CONFIG += incremental gdb_dwarf_index
              QMAKE_INCREMENTAL_STYLE = sublib

              include(../common/linux.conf)
              include(../common/gcc-base-unix.conf)
              include(../common/g++-unix.conf)

              modifications to g++.conf

              QMAKE_CC = C:\Sourcery_standard\bin\arm-none-linux-gnueabi-gcc.exe
              QMAKE_CXX = C:\Sourcery_standard\bin\arm-none-linux-gnueabi-g++.exe
              QMAKE_LINK = C:\Sourcery_standard\bin\arm-none-linux-gnueabi-g++.exe
              QMAKE_LINK_SHLIB = C:\Sourcery_standard\bin\arm-none-linux-gnueabi-g++.exe

              QMAKE_CXXFLAGS += $${COMPILER_FLAGS}
              QMAKE_CXXFLAGS_RELEASE += -O3

              QMAKE_CFLAGS_RELEASE = -Os -momit-leaf-frame-pointer
              QMAKE_LFLAGS = -static -static-libgcc
              DEFINES += QT_STATIC_BUILD
              load(qt_config)
              @

              makefile.win32
              ...

              LFLAGS = -static -static-libgcc

              ...

              do i need to set qt.conf?
