2 options:

• use a more recent version of ITK (which should work)
• use an older compiler version. I guess the file referenced will tell you which compilers are supported.

tks I did install the new version of ITK but it didn't work either. Do you know how to use an older compiler version? Should I just delete cmake or is there a way to use an older version directly?

[KrisThielemans]

I'd have hoped more recent ITK would work. We test in various configurations (see e.g. https://github.com/UCL/PETPVC/blob/master/azure-pipelines.yml). Can you give error messages please?

Switching compiler versions needs to be done in a new build directory (CMake cannot switch compilers after it has configured once). Best way seems to be to set CXX environment variable, as in

CXX=g++-8 ccmake ...

[garincle]

Hey, it seems that you were right (of course) =); my bashrc was still pointing at an older version of itk! and by updating it, the install worked. Thank you so much for your help.

[KrisThielemans]

Perfect. thanks for trying and letting us know.
