QtCreator: Issues not displayed in Issue panel any more

Question

I don't know what I did to break my QtCreator but "suddenly" all my compiler issues (warnings/errors) are not displayed in the issues-panel any more but only in the "Compile output" panel (where I can't use them to jump to the erroneous code just by clicking).

In the "Issues" panel only the compile target (e.g. an object file) is being displayed like this:

[path/to/makefile:89: path/to/object/file.cpp.o] Error 1

I'm using Creator together with CMake (with Makefiles) and GCC. The compiler output itself seems not to be the problem (another tool which outputs <file>:<linenr>: <description> shows the same result).

What are the requirements for Creator to correctly parse and display issues printed by the compiler (or any other tool)? How can I investigate what's going on?

I'm using QtCreator 4.6.2 on Fedora 27 (and I tried 4.8.0-beta1 as well with the same result)

Answer 1

I don't know the technical reason but for me creating a new build-folder solved the problem.

Possibly a CMake or Qt-Creator update introduced some new elements in the environment in an incompatible way..

Answer 2

For what it's worth, I was able to resolve a similar issue by resetting the compilers for each of my build and run configurations under Preferences > Build & Run > Kits in Qt Creator.

These had been set to <No compiler> for some reason, probably related to careless tracking of various CMake files while passing the project back and forth between different architectures.
