Hi Caspar,
thanks for the answer. What you assumed is almost right. I will explain
in detail what is my problem.
I create a MITK project with the project tmeplate and I start develop an
application following the tutorial steps.
I put all the code in the "SOURCE/Apps/AwesomeApp/"
(e.g for step1.cpp I have just copy/paste the code in AwesomeApp.cpp and
works fine)
Everything is working perfect since step6. What I did for step6 is
1. download all the files (step6.cpp, step6.h, step6RegionGrowing.txx,
step6RegionGrowing1.cpp, step6RegionGrowing2.cpp and step6main.cpp)
2. copy the code from "step6main.cpp" to "AwesomeApp.cpp"
3. import all the file (step6.cpp, step6.h, step6RegionGrowing.txx,
step6RegionGrowing1.cpp, step6RegionGrowing2.cpp) in my project
("SOURCE/Apps/AwesomeApp/")
Now when I try to build I get the "QMetaObject symbol not found" error.
What I have understood so far is that I need to add the "step6.h" file
into the list of MOC_H_FILES in files.cmake, but as you said is not
present in
"SOURCE/Apps/AwesomeApp/".
I tried to put it in different place but I cannot manage to make it
create the moc file.
Hope this explanation is clear :)
Thanks a lot for the help
Yari
