Hello,

I am compiling through ssh and screen as well, though X11 forwarding is off ($DISPLAY is empty). I'm trying to compile now using 15.1 and apparently it worked. I couldn't use version 17.0 since I don't have yet a licence for it. I'm using only 1 makefile and I'm targeting a Stratix V opencl board provided by bittware (s5-phq).

Thanks for the help anyway!

I checked my old emails and the discussion I had with my colleague regarding this issue. I think the issue is the same as the one caused by X11 forwarding, just the error is different if you are targeting SoCs (you are targeting an SoC, right?). Try the suggestions from this topic (disable X11 forwarding and unset display):

Also avoid having multiple make files that call each other or export variables.
