[Solved] Qt "forgets" to link one of my "moc_MyClass.o" objects.
-
Actually, the moc_MYCLASS.cpp is never created or built.
Why? It's in the project's headers and sources, has Q_OBJECT, and it just like any other class in my project.
Why won't moc get generated or built for my class? I narrowed the class down to simplest 'bare bones', and it passes compilation, a moc is never created though
-
Troubling resolution: removed the files(s) from my project, and added them back again. the moc is now generated. This is clearly a Qt "project cancer" bug.

What does [Bypasses] mean?
-
[Bypassed] - will correct.
-
Would [Solved] be more appropriate (and standard), perhaps?
-
Perhaps you're right.
-
I had a similar issue and I simply saved (ie., touch) my .pro file and that seemed to work.
-
I run into the same problems now and then. I usually solve it by doing a full rebuild (clean the project, re-run qmake (important!), completely rebuild the project). This way you ensure that qmake catches up all the changes and adds the necessary build steps (moc, uic) to the Makefile.
-
Its interesting because in this one instance a full clean and even restart of QtCreator did not fix it, it was not until I touched the .pro file that it finally worked. If in doubt, touch the .pro file then do as Volker says. ;)
-
In this case forcing a run of qmake should do the trick.
