      When I cross-compiled qt5.6.1 for my arm board, I got the following error:

      OpenGL ES 2.0 auto-detection... ()
      arm-arago-linux-gnueabi-g++ -c -pipe -O2 -Wall -W -fPIC -I. -I/home/smallbird/tslib1.4/include -I/usr/opengles2/include/GLES2 -I/usr/opengles2/include/GLES2 -I../../../mkspecs/linux-arm-gnueabi-g++ -o opengles2.o openglesp
      arm-arago-linux-gnueabi-g++: error trying to exec 'cc1plus': execvp: No such file or directory
      as: unrecognized option '-mfloat-abi=softfp'
      Makefile:177: recipe for target 'opengles2.o' failed
      make: *** [opengles2.o] Error 1
      OpenGL ES 2.0 disabled.
      The OpenGL ES 2.0 functionality test failed!
      You might need to modify the include and library search paths by editing
      QMAKE_INCDIR_OPENGL_ES2, QMAKE_LIBDIR_OPENGL_ES2 and QMAKE_LIBS_OPENGL_ES2 in
      /usr/qt-everywhere-opensource-src-5.6.1/qtbase/mkspecs/linux-arm-gnueabi-g++.

      However, I have already designated the Include and Library path and the header files and library files are got through the way that I cross-compiled mesa-12.
      Many people have came across this kind of problem ! Does anyone know the reason ?
      Hope this topic can help more people !
      Thanks in advance !

        @small_bird These directories are on your host PC:

        -I/usr/opengles2/include/GLES2 -I/usr/opengles2/include
        

        you need to use those from your sysroot.

          @jsulm I know what you mean. However, the compiler has found the headers and the libraries. Why it still tell me that I need to designate the path variables ?

            @small_bird The actual issue is this:

            arm-arago-linux-gnueabi-g++: error trying to exec 'cc1plus': execvp: No such file or directory
            as: unrecognized option '-mfloat-abi=softfp'
            

            I don't know why this happens.
            arm-arago-linux-gnueabi-g++: error trying to exec 'cc1plus': execvp: No such file or directory - looks like the C++ compiler is not found.
            as: unrecognized option '-mfloat-abi=softfp' - looks like the wrong assembler (x86) is called.

            Is your build environment broken? How do you call configure?

              -L/home/smallbird/tslib1.4/lib
              exit

              This is my configuration.

                @small_bird said in The OpenGL ES 2.0 functionality test failed:

                -sysroot /

                "-sysroot /"? So, your host PC file-system is your sysroot? This is for sure not going to work.

                  @jsulm Sorry for that, I have corrected it.

                    But you really remind me of some method.
                    There is some option that could change the configuration: -mfloat-abi=softfp.

                      It is -qreal option. However, it can only change the qreal type.
                      Then how to solve the problem ?

                        @small_bird The first problem to solve is:

                        arm-arago-linux-gnueabi-g++: error trying to exec 'cc1plus': execvp: No such file or directory
                        

                        It looks like something is wrong with your build environment. Are you able to build a simple C++ program with this environment?

                          @jsulm No, I can not build c++ program. The error is the same !

                            @small_bird Then I would say your build environment (compiler) is broken.

                              @jsulm Yes, I am checking for that. However, gcc compiler is all right.
