No rule to make target

[Emit]

I tried to run a program but the process stops due to the error

:-1: error: No rule to make target '../../../../../IBO_win03_1/mainwindow.ui', needed by 'ui_mainwindow.h'.  Stop.

:-1: error: No rule to make target '../../../../../IBO_win03_1/mainwindow.ui', needed by 'ui_mainwindow.h'.  Stop.

Does " ../../../../../IBO_win03_1/mainwindow.ui" actually exist? You seem to have two 'mainwindow.ui' files in your project file

[Emit]

I fixed it and it works now. It seems the problem was with .ui file.

[aamer4yu]

Can you state what the problem was ? It may help others

[Emit]

I don' t know exactly. I deleted the .ui file and paste it again and deleted some folders that were in project directory and after that the project compiled.

[Nomad_Tech]

If you have the same file in two different locations, Ie: "mainwindow.ui" and "../../../../../IBO_win03_1/mainwindow.ui" listed in your project file it will not compile.
