Qt6 porting, undefined symbol: _ZN10EngineBase16staticMetaObjectEHi
-
The symbol is from engine_base which has the macro:

@sebaro
Just make sure you have done an absolutely full, clean rebuild. Best is to actually delete the build output (not the source!) directory completely and then do a complete rebuild. Spend a couple of minutes verifying that before continuing.I use a build directory, and I clean it after each code change:
cd build cmake .. makeI replaced/removed deprecated and obsolete class members and changed the main and plugin cmake files:

@sebaro said in Qt6 porting, undefined symbol: _ZN10EngineBase16staticMetaObjectEHi:
I clean it after each code change
And precisely what does that mean? I suggested you delete the build output directory. If something like
make cleanthat may not be good enough. Just saying, up to you. -

I delete the content of build directory, I don't use make clean. Every cmake/make is with an empty build directory.
-
Simplify your testcase until you find the bug or you can post it here.
