    Hi,

    Yes, it's possible, but first you have to get OpenSSL for windows

      Yes I do have it. In the configure options I point to the include folder for OpenSSL as well as the lib folder

        Just C:\OpenSSL_win32\include or C:\OpenSSL_win32\include\openssl ?

          Not exactly but similar. The include is: C:\openssl-1.0.2d\include\openssl

            Then the path is one level too deep. You need to use C:\openssl-1.0.2d\include\

              Ok, I actually had one level down as you shown and the error persists. That is, ...\include\ and ...\include\openssl. Both were tried and yet had errors:
              fatal error C1083: Cannot open include file: 'openssl/ssl.h': No such file or directory (access\qnetworkreplyhttpimpl.cpp)

                Might be a silly question but did you pass the corresponding -I and -L arguments to configure ?

                  Yes. A part of the configure options is shown below:
                  -ssl -openssl -I C:\openssl-1.0.2d\include -L C:\openssl-1.0.2d\lib

                    When doing the -I and -L corrections, did you do it from a clean state ?

                        No: confclean.

                        Better yet: use a shadow build, this way you can keep your sources clean and just nuke the thing if you need to restart.

                          C:\Qt\qt5>nmake confclean

                          Stop.

                          Perhaps confclean is not a valid target in any of the created Makefiles?

                            confclean actually doesn't exist in Qt 5. IIRC, it was hard to make it work with Qt's modular structure. See https://bugreports.qt.io/browse/QTBUG-34304 for a discussion.

                            Did you get the source code from git? Or did you download the source package?

                                  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.
