          @Arasu these are c specific issue. scandir is a function in dirent.h. Check if it is there for Windows and include it.

              @Arasu dirent.h usually comes with C Posix Library. Which compiler kit are you using ?
              If msvc then you wont get dirent.h. Find out a way for how to include dirent.h on Windows.

                Hi,

                seems your projects includes some Linux/UNIX specific code.
                I suggest to understand if you can refactor it in order to be ported also on Windows (for example using Qt classes)

                    @Arasu I think you must start from Qt basics. Qt Creator is not a compiler but an IDE.
                    Please first check whether the code can be easily compiled on Windows. What are the required dependencies ? How much effort it would require for compiling ? etc..
                    If not easy then better to compile it on Linux as the first hitch (scandir) you came across can easliy be solved on Linux.

                      Hi,

                      Qt Creator is only a IDE, to build/run a project it uses the Kit configured for it.

                      Once your problem is solved don't forget to:

                        I am really sorry, i don't know these kinds of knowledge about QT Creator. Which is the compiler for both windows and linux. Let me know this for my knowledge

                          Hi,

                          the standard compiler for Linux is gcc and there is a porting of it for Windows MinGW.
                          But this doesn't mean you MUST use it (you're free to choose different compiler for each platform).
                          In example in my company release the same product for Windows, Linux and OSX and we use different compiler

                          • Windows (Visual Studio)
                          • Linux (gcc)
                          • OS X (clang)

                          Once your problem is solved don't forget to:

                          • Mark the thread as SOLVED using the Topic Tool menu

                            I will try to compile using these things.

                                      Whether your original problem is resolved ? You had some crash issue. Also this you are facing new error now. Please post the new question rather than asking in the same question.

                                      I can help you with both questions. Did you write simple program on linux platform with Qt creator ? Did it run ?
