Hi Kevin,
Thanks for the report.
You have set up the variable to 4GB.
However, the condition for the test is set up in
Insight/Testing/Code/IO/CMakeLists.txt
In lines 214-224.
The test requires
IF( ${ITK_COMPUTER_MEMORY_SIZE} GREATER 5 )
Because we create a > 2GB image, then saves it and then
reads it again.
In order to force the test to run you could fake the
number to 6GB.
Note that you could also reduce the test to just write a
file >2Gb, without attempting to read it again. In which
case, 3Gb of RAM will be more than enough.
That being said,...
Our observation is that, unfortunately, the MetaImage library
is not currently functional for writing files larger than 2Gb.
This has been entered as an issue in the Bug tracker:
http://public.kitware.com/Bug/view.php?id=6716
It is unlikely that we will manage to fix
this before cutting the release of ITK 3.6 :-/
Regards,
Luis
