Dependent (that clearly exists) does not exist error when building Qt Creator project

Cosmin124

I have the same exact error on Windows 10 with Qt 5.12.3, but not on macOS 10.14.4 with same Qt version. I did not get this error on Windows 10 with Qt 5.5.1.

I tried all the ideas above so this seems to be a bug in Qt 5.12.3 for Windows. Have you found any solution?

Do you use object_parallel_to_source ?

Cosmin124

@aha_1980 No, I don't.

@Cosmin124 It will be hard to help you without the actual project. At least all project files are needed.

If you want to investigate yourself, check the compile output. sometimes builds fail just because of timing, i.e. dependency is build parallel or after the project that uses the dependency.

Unfortunately I wasn't able to fix it @Cosmin124

Are other files from the same directory being included from this dir?

$$PWD/../../../GBusArtifact/Debug/interface/include/routercontroller/routercontroller_fw \

Have you tried doing an explicit include:

HEADERS += <absolute path>
or
HEADERS += <relative path>

Are there symbolic links in the path that could be screwing stuff up?

this might help:
add the following to .pro file

QMAKE_PROJECT_DEPTH = 0

this will make all Makefile includes to absolute paths

@saurabhjadhav1911 Add QMAKE_PROJECT_DEPTH = 0 to .pro file works for me, thanks very much.
