Hi,
Try adding "-mcmodel=medium" into PPLIST (makenek).
See the fifth item of thie FAQ for more.
https://nek5000.github.io/NekDoc/faq.html#installing-compiling-and-running
Hope this helps,

Thank you for reminding me. I actually tried adding "-mcmodel=large" into PPLIST (makenek) before, but it didn't work. I think it's probably due to my computer's memory issue.
