    Assuming that you checked out the code to C:\Qt\git, use the following commands to clean your source tree:

    > cd C:\Qt\git\
    > git clean -dfx
    > git submodule foreach "git clean -dfx"

    So this is in regards to making a correction and perform a re-build? I didn't do that for the initial build.

    From memory, I do a checkout, init-repository --no-webkit, and then perform the configure step and finally the call to nmake.

      My bad, old reflex from Qt 4. However, I'd recommend an out of source build, so you don't have to clean anything, just nuke the current build folder content and restart

        Hi,

        Not sure I understand what "out of source" means. I get the part about nuke the current folder. If what you mean is just delete the build folder and start again, then I must ask, does not doing a clean solve that?

          It literally means build from another folder outside of Qt's source tree so basically:

          cd qt_build
          C:\Path\to\Qt\configure 
          

          Indeed, the result is pretty much the same however It's generally faster (at least for me until now) to delete a folder than to recursively go through all Qt's modules and clean one after the other.

            Understood. Issue still dogging me though as to why it can't find the include files for openssl

              Yes.

              I didn't do that for the initial build.

              Before your initial build, your folders were already clean, so you didn't need to clean them.

              Yes, that sounds very useful and it works for both git and non-git sources, I'll need to try this the next time I build!

                Can you share the full configure line you are using and the build setup summary ?

                @JKSH
                Out of source is just so great, you should ;)

                    WOW! That is amazingly faster than nmake clean. Thanks for that.

                      Looking at the batch file in the root folder, it looks as if that file does essentially the same thing. i.e configure.bat cd's to qtbase\configure

                        Yes but it also triggers the build of the other modules, otherwise you will only build qtbase.

                        Can you try again with -openssl-linked ?

                          OK. So on my checked out build I have:
                          c:\Qt\qt5

                          You're suggesting:
                          cd c:\Qt\qt5
                          qtbase\configure

                          Is that correct?

                          There exists a configure script in both the root and the qtbase folder

                              So MyQt5Build is initially empty and is a target folder for the build correct? That's what you meant by shadow build?

                                Yes, the same thing happening by default when you build a project with Qt Creator

                                  There exists a configure script in both the root and the qtbase folder

                                  Do not use the script in qtbase directly. Only use the root script.

                                    Sweet success!. Cleaning the source tree using the git commands suggested as well as the proper level of path for the include folder for openssl worked. Thanks to ALL!
