Hi everyone,
Following my last month questions and with your help, I did manage to
install MITK 2015.05.2 using Qt4 on a new iMac. However, a few days ago I
updated the OSX El Capitan with a new security update and had to rebuild my
MITK plugins to update few changes I had in my code. Since, then I have
been facing strange problems, first of all the same MITK code was not
building again throwing errors at:
Modules/MapperExt/src/mitkUnstructuredGridMapper2D.cpp
Modules/MapperExt/src/vtkMitkOpenGLVolumeTextureMapper3D.cpp
Complaining about using delete[] for arrays in these two files, which I
thought might be due to a change in the OSX c++ compiler after the update.
So, I manually updated these two files and have noticed that in the nightly
version of MITK the same changes have been done. Following this, the code
actually gets built and runs normally but a strange crash happens when I
try to use the DICOM plugin and load a DICOM into the viewer. The
application crashes and quits. Are these events anyhow related?
I also tried to build MITK from scratch using the current developing branch
but it seemed that it is not stable yet as the code did not compile. Can
anyone please shed some light on these? Because, I think I am running out
of options to test.
Many thanks
Dora
