    No, that's fine. What exact error are you getting ?

          Can you show your .pro file ?

              Just double click it and it will open. Copy paste it here.

              Also , you seem to be on linux. You have gcc and build tools installed?

                  Just for test.
                  rename it to
                  myfile.c and put it next to main.c ( in same folder)
                  Then add it.
                  I suspect it might be path related.

                      But if you renamed the file,
                      why does it talk
                      about C.o ?
                      should be myfile.o or Chapter-9-Zadatak-6.o ?

                          well it surely works so im not sure why it fails in your setup.
                          Could u zip your test project and let me see it ?

                            At the very least your are missing quotes in your .pro files.

                            ../Desktop/C Reseni Zadaci iz Knjiga/Chapter-9-Zadatak-6.c each space tells qmake that what follows is a new file hence your errors with the "strange" paths.

                                  Hi
                                  Your project just worked here.
                                  alt text

                                  Complaining about you have 2 main functions -
                                  so there must be something wrong with your setup
                                  since it wont compile in your place.

                                  Can you create a Default Qt Gui project and run it ?

                                    yes i can run default and change it and run again, but the problem is with new files that i want to add. Im still google for solution :)

                                      Very odd.
                                      So the same project, do not compile proba.c
                                      even it does here ?
                                      Can you check your kit that there is a .c compiler assigned ?

                                        Are you adding files with spaces in the path ?
