Thanks a lot but these is not necessary, I have not problem on these .... but now is well done so can add system folder cancel mine so everyone can build it on QT6 ...

Any how if eliminate halwidget from project problem remain ... so my attached project .... (finally I purge it and with some fortunes i see is not problem of code ... but only a compile problem .... not find perhaps) ..... github.com/bkt-it/Lcnc-test-qt6 .....

I find that problem become from no linking on iniaxis.o .... and these research suggest me somethings not work on linkages from .hh and .h file .... but not an expert ... or not so mutch to solve the situation ....

Warning: Spoiler!
