Qt : No rule to make target '../controlpanel.ui', needed by 'ui_controlpanel.h'. Stop

Question

I met very strange problem on the Qt Creator.

:-1: error: No rule to make target '../controlpanel.ui', needed by 'ui_controlpanel.h'.  Stop.


mingw32-make[1]: *** No rule to make target '../controlpanel.ui', needed by 'ui_controlpanel.h'.  Stop.
mingw32-make: *** [debug] Error 2
makefile:34: recipe for target 'debug' failed
22:43:11: The process "C:\Qt\Qt5.4.0\Tools\mingw491_32\bin\mingw32-make.exe" exited with code 2.

This project compiled well before. But now I got compile error. I use Qt creator 5.4.0 on Windows.

And specially, this project compiled without any error on the Qt Creator 5.4.0 of Mac version.

What was wrong? How can I solve this error?

This is a qmake file.

Answer 1

I got the solution.

On Qt Creator, go into "Projects Tab", then you can see "Shadow build". Uncheck this and compile. The error disappears.

Answer 2

covernal's answer works fine if you are only targeting one platform. If, however, you are compiling for multiple platforms (e.g., Desktop & Android) you can keep doing the shadow build. Here's how I fixed it:

Find the project's build directory from the Projects tab:

Go to that directory and delete everything you find. Qt will simply recreate all the files it needs to rebuild your project.
