Changing source directory

[Dirty_Dylan]

So I have a source directory /home/project. I want to change this directory to to say /home/documents/project. If I cut and paste the contents of the folder I get
":-1: warning: The build directory needs to be at the same level as the source directory." when trying to compile how do I tell QT that I have moved folder.

What is generating that error message?

This is the compile output.

Call qmake prior to running make.

[Dirty_Dylan]

Thanks, it seems to be compiling now. However it still issues the same warning.

:-1: warning: The build directory needs to be at the same level as the source directory.

Could you explain step by step what you are doing? Are you using command line, Qt Creator or how else do you build your program?

[Dirty_Dylan]

I am using Qt Creator. I just build then run the program. I have also tried to clean and re-build.

[ChrisW67]

Qt Creator has an expectation that its shadow build directory will have the same parent directory as the source directory. The shadow build directory is not specified in the PRO file but in the Qt Creator, Projects, Build Settings. You will see the warning there also. It will also prohibit a shadow build directory inside the source directory: in this case it refuses to build.

This has been done to counter some qmake issues that can arise with shadow building inside the source tree (although I've never seen them myself).

[Dirty_Dylan]

Thanks, so you have to go to projects and then change the build settings from there. It is working now
