    Is the fix same?

    If you use 15.8 then yes - it makes no different if you build Qt static or not here.

          I replace the qalgorithms.h cleaned the cmake cache, did a full rebuild. And now it is working for me also.

          I am using VS2017 15.9.4 and doing a x64 build with release symbols.

            Then I would say - update to 5.9.7 and make sure no old Qt version is around and try again since it's fixed in 5.9.7

              @Christian-Ehrlicher you mean downgrade Qt from 5.12.0 to 5.9.7 - that's quite an old version. I need the high-dpi support in Qt.

              Can anyone look into this issue, I'm sure I'm not the only one on 5.12.0 branch using VS2017?

                You're using 5.12? Then the fix is in there already... the problem here was only due to problems with Qt5.9.5/.6 and VS 2017...
                Do you compile Qt on your own?

                      @Taytoo May I ask which header file you changed, and what exactly? Thanks!

                      Qt has to stay free or it will die.

                        @aha_1980 The change was in qcompilerdetection.h Line: 1349.

                        Weird thing is that now that I've fixed the linker issue I was experiencing, compiler is Not complaining of the code - I've reverted qcompilerdetection.h back to its original version. Even though, looking at the file in VS the offending lines are still marked red, I guess moc is taking care of it somehow.

                          Hello,
                          I am using QT5.13.1+VS2017 and I have encountered this kind of error. I am very surprised that the latest version will have such a problem.

                            Did you compile Qt by yourself? I've no problems with MSVC 2017 + Qt5.12/5.13 so make sure you don't use an older compiler or something similar.

                                  I am using MSVC 2017 Enterprise Edition 15.9.16.
                                  And Is this a problem with this version?

                                    Not, that should be fine - there were some problems with 15.9.0 - 15.9.7 or 8 (iirc) but not with the current one. Are you sure you're not fetching an old compiler? How do you compiler your code? What does "cl /?" on the command line from where you compile says?
