University license for OpenCL?

Hello,

I'm trying to follow the introduction to OpenCL videos (https://www.youtube.com/watch?v=4pukzi14mly) but I'm currently stuck when trying to compile OpenCL for my board: 


aoc device/vector_add.cl -o bin/vector_add.aocx --report
aoc: Selected default target board s5_ref                        
/home/renagen/opt/intelFPGA/16.1/opencl_example_vector_soc/vector_add/device/vector_add.cl:23:48: warning: declaring kernel argument with no 'restrict' may lead to low kernel performance
__kernel void vector_add(__global const float *x, 
                                               ^
/home/renagen/opt/intelFPGA/16.1/opencl_example_vector_soc/vector_add/device/vector_add.cl:24:48: warning: declaring kernel argument with no 'restrict' may lead to low kernel performance
                         __global const float *y, 
                                               ^
2 warnings generated.
Could not acquire a valid license for the Intel(R) FPGA SDK for OpenCL(TM).
Error: Verilog generator FAILED.
Refer to vector_add/vector_add.log for details.

The LM_LICENSE_FILE is pointing to my license file which contains: 

#  Altera SDK for OpenCL (University), 1 Seat(s)#  - Maintenance Expiration of 2018.01

Have you ever experienced such kind of error?

Does anyone know if the University license is compatible for such use?

Thanks.

    Yes, but the only times I have seen this issue is when either my environment setting was wrong, the license itself was wrong, or if I had placed the file in the wrong location...

    Thanks for the feedback. A simple 

    cat $LM_LICENSE_FILE
    tells me that it's actually correctly set.

    It must come from the license itself. Has anyone here already tried with a University license ? :)

    Are you running on Linux? The network interface needs to be named eth0. If you have a reasonably new Linux distro it is probably named something like enp0 (check by e.g. typing "ip link show" in a terminal), but you can create a virtual network interface with the name eth0 with the MAC (also called NIC) adress that is specified in your license file: 

    
sudo ip tuntap add dev eth0 mode tap
sudo ip link set dev eth0 address <your mac address>

    Great, it works now!

    Yes, I am running archlinux (I should have read the dedicated wiki page there, it was also explained).

    Thanks a lot!
