    Looks good

    Do you have all the modules built before calling make install ?

        Look at the content of your build folder and check the qtbase/lib folder.

          Here are the contents o my lib folder.
          One thing, do i need some more modules to build it, i mean there might be some modules depending on some other modules i might have skipped.

            I don't see there any of the modules that are missing.

            One thing you can do is build them by hand using the classic qmake, make, make install. Do it out of source, it would be best.

              ====================================
              upon "make module-qtbase' this is the outcome.
              i did clean installation again, and build in seperate folder not in src folder

                  Did you run the script from the gist or just one line after the other yourself ?

                  Did you call configure several times ? If so, did you do it from a clean state ?

                    I run it myself , one line after another.

                        Just to be sure, you have all modules built and installed now ?

                        If so, new your project build folder and re-run qmake.

                            @Izza Try to install the compiled Qt framework then run qmake from the installation folder. For me the instructions found here:

                            https://blog.qt.io/blog/2019/03/05/using-docker-test-qt-webassembly/

                            worked, but I needed to run

                            /usr/local/Qt-5.13.0/bin/qmake

                            i.e. from the install folder
