FPGA compile error (DPC++)

I get this error every time i compile any DPC++ code for FPGA. At first i thought the problem was in my build script but then i tried with vector-add sample and get the same error. When following the steps in get started guide, error happens at step 2.2 when submitting compilation job; so for example when i submit it with

qsub -l nodes=1:fpga_compile:ppn=2 -d . build_fpga_hw.sh

it would go to node s001-n059 and compilation ends with error after like 8 mins. The thing is that compiling for hardware used to work one month ago with no problem but now i can't get one simple sample case to compile.
