Hi, I do not think this is the case, Arpack is not turned on by default and needs to be turned on via cmake. Easiest to do is to have Arpack installed through your system package manager, and just let the cmake find it. Also, it is helpful to use the cmake terminal "gui" ccmake - to see all the possible options. Best, Stan On 04/28/2018 01:56 AM, Amitvikram Dutta wrote:

Hi all, I've installed nektar++ as directed and all the ctests pass. However when I try to run one of the example cases, I get the following error.

Fatal   : Level 0 assertion violation Value 'Arpack' is not valid for property 'DRIVER'

I have installed Arpack separately on my machine but I'm not sure if I have to link it separately to nektar++ installation in some manner.

Additionally I left all the cmake options on default as they were. I assumed this meant that Nektar++ had built the third party arpack installlation as directed.

How should I proceed?
