und zwar habe mal das Qwt Extension runtergeladen und die Examples funktionieren auch sehr gut und es hat mir ein Example mir sehr gut gefallen und habe die Klasse in mein projekt eingebunden und wollte es mal als Widget mit aufblenden lassen und beim kompilieren gibt er mit diesen Fehler heraus:
Ich kanns eigentlich verstehen, weil das Example alleine funktioniert und nur wenn ich das jetzt in meine .h mit einbinde gibs einen Fehler!C:\PROGRAMMIEREN\CPP_PROJECTS\qserver>make

So sieht mein config file aus:
Habs mir eigentlich von der exmples.pri bisschen abgeguckt wie die ihre config gemacht haben und das müsste eigentlich funktionieren######################################################################

!Wenn ich jetzt die qplot_widget.h (per #include) aus meiner qserver.h wieder entferne ist alles wieder in Butter
!Ich weiß nicht woran das liegt :/? Nach dem Code liegts eher an der qhash.h die Probleme macht.
