    Hi ,
    I am trying to compile qt-everywhere-opensource-src-5.7.1.
    configuration:
    ./configure -xplatform linux-arm-gnueabihf-g++ -prefix /usr/local/Qt5.7.1_opengl -opengl es2 -confirm-license -opensource -no-cups -no-largefile -optimized-qmake -nomake tools -no-pch -v -no-icu -no-openvg -sysroot /home/antriksh/ti-processor-sdk-linux-am57xx-evm-04.02.00.09/targetNFS -I/home/antriksh/ti-processor-sdk-linux-am57xx-evm-04.02.00.09/targetNFS/usr/am57xx-evm/usr/include/

    I have added qmake.conf for linux-arm-gnueabihf-g++

      @Biswajit_1984 said in QT5.7.1 Cross Compilation issue while compiling for AM5728(OMAP5):

      uses VFP register arguments

      You should start again from a clean source tree (or delete the build directory if you did out of source build).
      It looks like you tried before with different parameters (QMAKE_CFLAGS_RELEASE) and still have object files built for different ABI.

        Thanks a lot.
        Now the above errors are not there.
        But not its shows error:
        cannot find -lqtpcre

        When i cross check inside qtbase/lib then only below files relate to pcre are there
        qtpcre. qtpcre.prl qtpng.prl

        Let me know do i need to install perl in the host also?or any other issue is there

          @Biswajit_1984
          I have tried to disable pcre .But it seems there is no option to disable.
          Please let me know if i can disable the same to avoid the pcre building.

          Regards,
