Qt Creator 错误无限循环

Question

When I try to create a project which was developed by someone working in a different country and timezone I keep getting the following error in my console. He had mentioned this problem is because of the Data/Time being different from his computer to mine. I'm not sure if that is true, if it is, there has to be a solution for that without having to change my computer time to match his. I'm not sure what else to post that would be helpful in trouble shooting this, if there is just let me know and I'll update. I'm a bit new to C++/Qt Creator. Why is this happening. It seems to never finish, it just endlessly prints this to the console.

Answer 1

This can happen if your .pro file (or any other file) has a timestamp from the future. The Makefile generated by qmake contains a rule that will generated the Makefile anew when its older than the .pro file. Since the new Makefile is still older than its counterpart from the future, this will go on till you actually reach the correct time.

There are two ways to get rid of this behavior:

1. Wait till the .pro file's timestamp is in the past (not recommended)
2. Edit the .pro file. Even a trivial edit like a new comment should be enough.

Answer 2

Had the same problem with latest version of QtCreator (3.6.1 with Qt 5.6.0).

Answer proposed by "Zeta" did not help.

Disabling "Shadow build" in project options fixed the problem for me. That's a good workaround.

Finally shorten file names (somes where huge) to fix the issue:

• Shortened project names (.pro) (file name and path, removed a few caracters)
• Shortened resources names (.qrc) (file name and path, removed a few caracters)

Issue then disappeared (even with shadow build, it's probably related as shadow-builds are using an output folder with a very long name).

There's apparently a bug when file paths are too long (>~170, found a post on a forum reporting that ).

An alternative is also to change the pattern used by QtCreator for shadow builds. This can be modified from the QtCreator options and you can then make the name shorter, this is another way to quickly and easily fix the issue.

Answer 3

I wrote a python script that loops through recursively through all the files of the project and simply just resaves the files. That updated the timestamp and corrected the QMake Infinite loop. It now compiles correctly.
